Aquarobot and what you need to buy in addition. Aquarobot turbipress automatic pump control unit, installation and operation manual. The pump does not turn on

AQUAROBOT pumping stations are an inexpensive and very high-quality product for those who want to organize an autonomous water supply system in their home. The main advantage of this system is that it is fully equipped, so installing and connecting it requires minimal effort.

AQUAROBOT pumping stations - principles of operation

A feature of AQUAROBOT stations is complete adaptation to current conditions, without installation additional equipment. Their advantages over standard pumping stations with a hydraulic accumulator:

1. The pump starts the station flow sensor when the water tap is opened. And after it closes, the microprocessor that controls the pumping station, with a twelve-second delay, stops the pump. Thanks to this, the equipment pump is reduced and energy is also saved.
2. Automatic shutdown of the pump when there is no water in the system - this prevents engine combustion.
3. Effective work pumping system, at low water flows, with a minimum number of inclusions.
4. AQUAROBOT operates at a reduced network voltage in the range from 75 W to 220 W, since a conventional system will have difficulty performing its functions.

Main classification of pumping stations AQUAROBOT

AQUAROBOT pumping stations can be equipped with both surface and deep pumps. Using them, water can be supplied to the house from underground wells, wells and other sources. Also, these water supply systems can be used for watering garden plots.

Main types of stations:

1. Adaptive stations are controlled by a microprocessor, which receives a signal from a flow sensor mounted at the pump outlet. They have a very compact size, but at the same time they are capable of drawing water from wells up to 8 meters deep.
2. Universal systems – additionally equipped with a pressure switch. With its help, the range of switching on and off the device is adjusted. These models are ideal for increasing pressure in centralized water supply systems.

Pumping stations are designed only for pumping exclusively cold liquid - up to 35 degrees.

AQUAROBOT installations have high performance qualities. They are capable of providing high water pressure at constant pressure, at a given level, and also work autonomously. These systems are protected against undermining and water hammer.

Today, owners of private houses in our country, accustomed to the dominance of European and American manufacturers in the market pumping equipment, increasingly abandoning stares for domestic brands.

One of them is the AquaRobot trademark - in Lately arouses keen interest among the knowledgeable public.

We decided to get to know the products of this manufacturer better, and at the same time tell our readers about their features.

AquaRobot pumping stations (PS) are an inexpensive and high-quality solution for those who intend to organize an autonomous water supply network in a house or on a site outside the city limits.

Each model is supplied fully equipped, so To get started, the owner only needs to connect it to the water supply network and a source of electricity.

This completely ends the user’s participation; the AquaRobot NS performs all its functions automatically, while maintaining optimal parameters in the water supply system.

A feature of AquaRobot pumping stations is a well-thought-out comprehensive safety system that takes into account any emergency situations that may occur:

• turning off the pump if there is no water in the suction line (dry running of the pump);
• turning off the pump if the impeller is blocked or jammed;
• turning off the pump if there is no air pressure in the storage tank;
• the station recognizes the presence of leaks in the water supply network and in this case does not pump water;
• the station adapts to the parameters of the water supply network and, in case of technical problems, responds by lowering the pressure or completely turning off the pump;
• equipment is blocked in case of incorrect connection to the pressure or suction lines.

Unlike imported pumping stations, which are very picky about the quality of power supply, NS AquaRobot easily tolerate significant voltage drops even up to 120 V.

Seasonal summer residents will appreciate the mobility of the AquaRobot NS, which, due to its light weight, can be easily and quickly dismantled when cold weather arrives.

Operating principle^

Under the AquaRobot brand, two types of pumping stations are produced, which are positioned by the manufacturer as universal and adaptive.

Universal NS^

The device that controls the operation of the pump in this system is a pressure switch.

It starts the pump drive when the pressure in the network drops, which occurs while using the water supply, and turns it off as soon as the pressure returns to its previous value.

At factory settings the threshold for switching on and off corresponds to pressure values ​​of 1.5 and 3 atm, respectively, however, the user can reconfigure the relay at his discretion.

The switch-on threshold is adjustable from 1 to 2 atm, the switch-off threshold is adjustable from 1.8 to 4 atm.

All models of universal stations equipped with a membrane hydraulic accumulator with a capacity of 24 liters.

Pumping stations with a capacious hydraulic accumulator and controllable the best way Suitable for domestic needs where water is consumed over short periods of time.

In addition to the pressure switch, you will also need one; it is designed to maintain a constant pressure level, eliminating water leakage from the system and possible pump stoppage.

Adaptive NS^

In these station models, the pump is turned on by a signal from the flow sensor. In addition, the pump motor will start when the pressure in the water supply drops below 1.53 atm.

Adaptive hydraulic pumps AquaRobot are equipped with small-volume hydraulic accumulators (2 and 5 l), which are necessary to start the pump and smooth out the resulting water hammer.

Low-pressure systems controlled by flow sensors perform best in applications where water is primarily used over long periods of time, such as for irrigation or filling a swimming pool.

With such a consumption pattern, the pump operates stably, and does not “twitch”, turning on and off, which would be observed when increasing the power of the station and equipping it with a pressure switch.

In this case, there is no need to use a large-capacity storage tank, which is designed to compensate for water consumption during short-term use of the water supply.

Selection of pumping station ^

The AquaRobot automatic pumping station is selected according to the following parameters:

• suction depth;
• pressure;
• performance.

The maximum suction depth for various models of NS AquaRobot is 5 and 8 m.

When choosing a station based on this parameter, you should take into account that the water level will drop slightly during pump operation, so you need to provide a small reserve.

The pressure and productivity of the station are interdependent quantities. In addition to their maximum values, the passport for the pumping station contains tables or graphs called the main characteristics of the pump.

They show what performance the station pump will have at a given pressure. Essentially, pressure is the pressure that the pump has to develop in order to provide the required water supply parameters.

To calculate it, add up the required pressure at the farthest point of consumption ( the optimal value is usually 2 atm or 20 meters of water column), the height of the maximum point of the network relative to the pump and pressure loss due to hydraulic resistance in the pipeline.

The last component is calculated using a rather complex method, but it can be replaced with approximate empirical data: every 10 m of pipe, the pressure drops by 0.1 atm (1 m v. Art.).

The required performance can be calculated based on the number of connected consumers and how often they will work simultaneously.

An easier way is to use experimental data as a basis.

Thus, the peak volume of water consumption for garden plot(possibly with small house) is 0.8 – 1 cu.m. m/h; for a cottage (standard project) with a resident family of 4 – 6 people – 1.5 – 2 cubic meters. m/h; for a solid mansion with a swimming pool or fountains - 4 cubic meters. m/h or more.

Now we need to choose a station model, in the main characteristic of which the pressure we have calculated will correspond to the productivity we need.

The main element of any autonomous water supply system is a pumping station, which, like any other technical device, may periodically fail. In order to return pumping equipment to working condition, you can use the services specialized companies or repair the pumping station yourself. However, before starting to repair such a rather complex technically equipment, it is necessary to identify the reasons why the water pumping station is not functioning.

There are many reasons for malfunctions in a pumping station. They may be associated with a lack of power supply, improper water supply from a water supply source, breakdown of the pump itself, failure of the hydraulic accumulator or elements that provide automatic control of the equipment. Many of these reasons that lead to the fact that water supply stations do not work or function incorrectly can be identified and eliminated at home, and repairs do not require professional skills and complex equipment.

Construction of pumping stations

Pumping stations, which are often called hydrophores, are now actively used to organize autonomous systems water supply to country houses and cottages, so the question of how to independently repair such equipment, if the need arises, is quite relevant. Before you figure out how to repair a pumping station with your own hands, you need to understand what such stations consist of and on what principle they work.

Pumping station for equipping water supply household use, which pumps liquid into the pipeline system, is installed on the surface of the earth, as close to the well (as possible), and operates from the network electrical supply. The main structural elements of pumping stations that ensure efficient and uninterrupted operation of such equipment in automatic mode are:

• the water pump itself, which pumps water from a well or a well and pushes it under pressure to the outlet pipe (to equip pumping stations, a surface pump, rather than a submersible one, is used);
• a water intake hose that is immersed in water to the maximum possible level;
• a check valve that prevents water from the suction pipeline from flowing back into the well or well;
• mesh filter installed in front check valve and purifies the water pumped from the source from particles of dirt and sand, which enter into inner part pump may be one of the reasons for its failure;


• a pressure sensor installed after the pump - on the pressure line (the main task of such a sensor, operating in automatic mode, is to turn on the pump if the water pressure in the water supply system drops to a critical value, and turn it off when it reaches the required parameters);
• a water flow sensor, which is installed before the pump and does not allow it to idle (when water stops flowing from a well or well, such a sensor automatically turns off the device, preventing it from overheating);
• a pressure gauge that allows you to measure the water pressure in the pipeline created by the pumping station.

Malfunctions of a pumping station, as mentioned above, can be determined by a number of reasons, the exact clarification of which will allow repairs to be carried out promptly and with the highest possible quality, returning the equipment to working condition. Diagnostics carried out to determine the cause of a pumping station breakdown do not require the use of complex equipment and professional skills. Reveal the majority typical malfunctions pumping stations can be identified both by external signs and with the help of instruments that were originally equipped with such equipment and the water supply system.

Among the malfunctions of pumping stations, we can highlight several of the most typical ones, which each user is able to identify and eliminate independently, using the advice of specialists during repairs.

The pump works, but no water enters the system

When starting a pumping station, it may happen that the pump with which it is equipped works, but no liquid flows into the water supply. To determine why the pumping station does not pump water, it is necessary to analyze individual parameters and operating conditions of the elements included in the equipment.

• First, you need to assess the technical condition and correct operation of the check valve, which is located on the suction pipe in the inside of the well or well. Very often the pumping station does not pump precisely because this valve is clogged with sand and dirt: without opening, it simply does not allow water from the well to flow to the pump.
• You should check whether there is water in the part of the pressure pipeline that is located between the pump and the well. If there is no liquid there, then, accordingly, the device has nothing to pump. Often this situation occurs when there is a power outage and the pumping station stops operating. In order for the pumping station to start operating normally again, it is enough to fill this part of the pipeline with water, for which a special hole is provided in it.


• It is necessary to check (with the pump disassembled) how large the output is between the inner walls of its housing and the impeller. Such production is formed most intensively in cases where water containing in its composition is pumped. a large number of insoluble impurities (a kind of abrasive). If this particular reason for the lack of water in the water supply system while the pumping station is running is identified, then repair of the pump is necessary, which consists of replacing the impeller and device housing, or its complete replacement. If you find components suitable for your equipment model, you can repair the water pump yourself.
• It is also necessary to determine whether there is water (and at what depth, if any) in the well itself. If there is water in the water supply source, then the problem can be solved simply: just lower the supply hose or pipe to a deeper injection level. In this case, it is necessary to follow the operating instructions for the pumping equipment in order to subsequently avoid its repair.

The pumping station operates jerkily

A pumping station operating in automatic mode may begin to turn off and turn on frequently, which indicates the presence of malfunctions. This type of operation of the pumping station, in which it is constantly switched off and on, is called jerking. This should be a signal to check (and, if necessary, repair) individual elements of the system.

If the pumping station operates jerkily (it turns off and then turns on), you should measure the pressure in the air chamber of the hydraulic tank. To perform this procedure, you can use a car compressor equipped with a pressure gauge. If this parameter in the air chamber or bulb for the pumping station is below normal, it must be raised using the same auto-compressor. A repeated drop in pressure in the air chamber of the device indicates that a depressurization of the system has occurred, the location of which must be identified. If the joints have lost their tightness, then repair of the hydraulic accumulator is not required; it is enough to simply replace the sealing tape in such places.

The body of the hydraulic accumulator may also lose its seal if a crack or hole has formed in it. Repairing the hydraulic accumulator with your own hands in such a situation is not difficult: to do this, just close the resulting crack or hole using a “cold welding” compound.

Why does the pumping station often turn on and off during operation? The answer to this question may also lie in damage to the accumulator membrane. In such cases, the solution to the problem is to replace the accumulator bulb or such a membrane.

Replacing the membrane in the hydraulic accumulator

Repair specialists are often asked why the pumping station often turns on or why the pumping station does not turn off when the liquid pressure in the water supply system exceeds the norm. This is usually due to a breakdown or malfunction of the pressure switch. Such malfunctions can also cause the pumping station to not maintain water pressure in the pipeline. Repairing a pressure switch is a rather complicated procedure that cannot always be done with your own hands. That is why, in many cases, the pressure switch of the pumping station is not repaired, simply replacing such a sensor with a new one.

Unstable pressure of the water flow coming from the pumping station

One of the fairly common situations when operating pumping stations is the supply of water from taps in pulsating jolts, which indicates that the water supply system is sucking in air from the outside. To identify where air has entered the pipeline, it is necessary to carefully check everything for leaks. connecting elements, present in the area located between the well or borehole and the pumping station.

If the pumping station does not build up pressure or pumps water into the pipeline in a pulsating mode, this may also indicate that the water level at the source has decreased or that a hose or pipe of the wrong diameter is being used to pump out water.

When choosing a hose or pipe for placement in a well or borehole, you should always take into account that their diameter should be smaller, the lower the suction height of water from the source.

The automatic shutdown system of the pumping station does not work

The question of why the pumping station does not turn off automatically is quite common. A pumping station operating in such a mode, which is considered an emergency, cannot be operated; it should be immediately disconnected from the power supply. Otherwise, you may experience rapid equipment failure, which means that more complex and expensive hydrophore repairs will be required.

Why does the pumping station not turn off for a long time? The reason is incorrect operation or failure of the pressure sensor. A malfunction of this device, which operates in automatic mode, may cause the pumping station to not turn on when the pressure of the liquid flowing through the pipeline decreases. In most cases, this problem is solved quite simply - by adjusting the sensor to the required pressure to turn the pump on and off.

The pressure switch may not work properly due to the fact that the elements of its internal structure are covered with salt deposits. In such cases, it is enough to disassemble the sensor and clean it internal parts from such deposits.

The pumping station does not turn on

In most situations, the station does not turn on (and, accordingly, the pump does not work) due to a break in the electrical circuit, oxidation of the elements of the contact group and malfunctions of the pressure sensor. In addition, the causes of problems may lie in a burnt-out winding of the drive motor, as well as in the failure of the starting capacitor.

As a rule, no problems arise with such repair procedures as eliminating breaks in the electrical power supply circuit of the station, cleaning the contacts of the starting device and replacing the capacitor. However, in order to rewind an electric motor, you need to know how to disassemble it and how to replace a burnt winding in it. That is why many users of pumping stations, when the drive motor burns out, simply replace it with a new one, avoiding repairs.

Often when starting a pumping station, which long time has not been used, a characteristic hum occurs, but the equipment does not start working. The reason for this situation is that the pump impeller of the pumping station is simply “stuck” to the body of the device and cannot budge. In this case, it is necessary to partially disassemble the pump of the pumping station and manually move its impeller from its dead center.

How to properly install a pumping station

In order to less often wonder why the pump does not pump water from the well or supplies it incorrectly to the system, serious attention must be paid to the installation of pumping station elements. Correct installation water supply systems with submersible pumps are no less important, since repair deep well pump or replacing it is also an expensive procedure.

So, when installing pumping stations, you must strictly follow the following recommendations:

• avoid bending and deformation of pipes used for installation;
• ensure absolute tightness of all connections made to prevent air leaks into the system;
• be sure to place a check valve and a filter element on the supply pipe;
• immerse the lower end of the inlet pipe in water in a well or well at least thirty centimeters (in this case, the distance of the end of the pipe to the bottom of the water supply source must be at least twenty centimeters);
• with a significant depth of the water supply source (more than 4 m) and, if necessary, to pump water over a significant distance, increase the design diameter of the pipes used for installation;
• use a water flow sensor and a pressure switch to equip the pumping station;
• locate the pumping station, which is installed on a hard and level surface, next to the water supply source;
• after installing the equipment and connecting it to the water supply system, draw water into that part of the suction pipeline that is located between the pump and the well or well.

Hello, dear forum users!
I am writing to you with a pressing question. This is the second year that the Aquarobot Turbipress has been installed, and both years it works through the stump into the deck, and often does not work at all. What is it? Some time after installing (last season it was installed by a company) the pump and Aquarobot, everything worked fine. After some time, problems began, first the pump stopped turning on. the fault was with the pump. I submitted it under warranty to the installer for inspection. They said the pump was working, I just didn't have enough voltage. They say install a stabilizer. I returned the pump to its place. I installed the stabilizer. It seems to have worked. (I later read this in the instructions for the Aquarobot, which I found on the Internet, that it must cope with surges and drops in voltage in the network). This season the same thing started happening - at a certain point the pump stopped turning on. I freaked out. I bought a new pump and, just in case, a new Aquarobot. Changed the pump. I changed the Aquarobot - nothing started. Returned the old Aquarobot. Everything is working. After some time, we had to change the architecture of the pipes somewhat. Everything after the robot was disassembled and rebuilt. I turn it on - it doesn't work. When I turn it on a second, third, fifth time, the following happens: it works for 15 seconds and turns off. I read the instructions, it says that this can happen if the system board is faulty. While I was reading, some time passed, I turned it on again - it worked. It works, but one connection skips a little (drops). I went through everything again and since then Aquarobot has completely refused to turn on the pump. I've been trying for the third weekend and it doesn't turn on.
Sorry for the somewhat chaotic presentation, but only those who think clearly can explain it clearly, and I am already somewhat confused in what is happening.
In general, summarizing this entire stream of consciousness, I can say that empirically It revealed:

Commissioning and programming After the hydraulic connection and electrical installation, the system must be filled with water and vented. To do this, you need to open the taps at the points of water consumption and put the device into calibration mode. Connect the device to the power supply, 10

11 RU The green LED will start flashing for 30 seconds. When the green LED is flashing, press buttons 1 and 2 simultaneously and hold them down for about 5 seconds until the green LED goes out (this will indicate the device has entered calibration mode). Then press and hold down button 2, the pump will turn on and start supplying water, which will remove air from the system when the taps are open. Keep pressing button 2 until the system is filled with water, displacing all the air, then close the taps. Set the required values ​​of P max and P min: with the taps closed, press button 2 and pump pressure P max into the system; the pressure value in the system must be read using the pressure gauge on the device body. Briefly press and release button 1. Flashing red LED indicates memorization of P max. open the tap and reduce the pressure in the system to P min. Close the tap. Briefly press and release button 1, the blinking of the red LED indicates that the pressure P min is stored. Switch from calibration mode to working mode auto mode by pressing and holding button 1 for 5 seconds. A sign that the device has entered automatic mode will be a flashing or uniform glow of the green LED. If necessary, multiple programming and changing of the threshold values ​​P max and P min are allowed. User-specified thresholds are saved when the pump is running and when the device is disconnected from the power supply. Note: In normal mode, the pump turns on at a pressure below P min and turns off at a pressure above P max. 11 Technical support

12 When the mains voltage is reduced, or when the pressure characteristic of the pump is reduced, the operating algorithm of the device is as follows: When the tap is closed, the pump turns on at a pressure below P min, and turns off 30 seconds after the water flow rate into the hydraulic accumulator is reduced to 3 l/min, or when the pressure in the system will reach the value P prev. When the tap is open, the pump turns on at a pressure below P min, and turns off 30 seconds after the water flow rate has decreased to 3 l/min. Installation and operation manual for AQUAROBOT TURBIPRESS Emergency stop pump In the event of a “dry running”, the device performs six emergency test runs, lasting 30 seconds, after 5, 20, 60 minutes, then after 6, 12 and 24 hours. If there is no water during the full cycle of test runs, the pump is switched to emergency mode. When water appears during a test run, the pump automatically turns on and goes into operating mode. The emergency mode can be removed by pressing one of the buttons 1 or 2. Test runs can be canceled and the pump can be forced into operating mode by pressing button 1 or 2, after first making sure that the cause of the emergency has been eliminated. Indication of operating modes 1. The green LED flashes evenly, the pump is running, there is a flow of water. 2. The green LED lights up continuously: a) The pump is turned off, the pressure in the system is P max. b) The pump is turned off 30 seconds after the water flow stops. 12

13 RU Note: The shutdown pressure in this case depends on the parameters of the pump and the capacity of the hydraulic accumulator, but is less than or equal to P max. 3. The red LED flashes intermittently; the pressure in the system has reached the value P prev (5.5-7 bar), the pump is turned off. 4. The green and red LEDs flash evenly, test run mode, the pump is turned on. 5. The red LED flashes evenly between test runs, the pump is turned off. 6. The red LED lights up continuously in emergency mode, the pump is turned off. 7. The red LED blinks evenly with a frequency of 1 time/sec; break or short circuit in the pressure sensor. When the pressure sensor parameters are restored, the red indication automatically disappears. Maintenance and storage rules During operation, the device does not require maintenance.

The pumping station is working (the pump is spinning), but there is no water:

The steps to resolve this issue are as follows:

• First of all, you need to check the check valve, which is located in the water in a well or well. It often happens that sand or debris gets into it and the valve does not close. In this case, the water does not rise through the pipes to the pump.
• Secondly, check the presence of water in the pipeline between the well and the pump. The pump must also be filled with water; if there is no water, fill it through the filler hole.
• Very large gap between the impeller and the pump housing. The pump simply works on its own. The reason for this may be the high content of abrasive substances in the water, such as sand. In this case, you should change the housing and impeller, if they are commercially available, or the entire pump (but not the entire station!).
• The well/well simply ran out of water. The solution is to try lowering the suction pipeline or hose deeper. But remember: the distance from the water level in the well to the pump should not exceed that indicated on the pump, usually 8-9 m.

The pump pumps jerkily (turns on/off very often):

To fix this problem, you need to do the following:

• Pay attention to the pressure gauge, which is located on the automation unit. If the pressure gauge needle rises to the pressure at which the station was set (at which point the pump will turn off), then drops sharply until it turns on, then there may be the following reasons:
• there is no air pressure in the hydraulic tank. At the factory, nitrogen is pumped into the tank to a pressure of 1.5 atm. Sometimes, due to corrosion, cracks appear in the tank body and the pressure does not hold for long. You need to find the leak and seal the crack (for example, “cold welding”). You can check the air pressure in the hydraulic tank by connecting a pressure gauge (at least a car gauge) to the nipple. The pressure in the tank may not necessarily be due to a crack, but simply due to unknown reasons, the air has escaped. Then you don’t need to drive yourself crazy in search of non-existent cracks, but simply pump up the air with a pump (in fact, that’s where you should start);
• rupture of the diaphragm separating air and water in the tank. You can check this through the nipple: if water flows from the nipple, it means the diaphragm is damaged;
• does not work pressure switch, which controls the activation of the pump.

The pump pumps, but the water flows intermittently (jerkily):

The cause of this malfunction of the pumping station and the measures to eliminate it are as follows:

• There is an air leak somewhere. It is necessary to check the suction pipeline from the wells to the pump, the connections and the water level in the well. The suction height should not exceed 8-9 m (for a pipe diameter of 1” - 25 mm; if the pipe is of a smaller diameter, for example, 1/2”, then the height should be less).

The pump pumps, water flows, but the pump does not turn off:

This is precisely the reason - a malfunction of the pressure switch of the pumping station, which we deal with as follows:

• The pressure switch needs to be adjusted. For adjustment, the relay has two springs, large and small:

A large spring regulates the pump on/off (upper and lower limits). The difference in pressure between the upper and lower limits is regulated by a small one. After prolonged use of the pump, the moving parts of the pump wear out, and over time the pump can no longer create the pressure that was “prescribed” to it at the factory. Therefore, you need to reduce it using a large spring, turning it in the direction of the arrow to “-”. However, you should not get carried away with such adjustments;

• The inlet hole in the pressure switch is clogged:

If the water quality is low, then sometimes hardness salts form and the hole in the pressure switch becomes clogged. The relay simply stops responding. You need to remove the relay and clean it.

The pump does not turn on:

Here are the steps to resolve this pumping station problem:

• look at the contacts of the pressure switch - use a tester to check the presence of power supply. If the contacts are burnt, clean them (for example, with fine sandpaper or a needle file);
• check the pump motor, check the contacts, power supply, “ring” for the integrity of the winding, check the validity of the starting capacitor. If the motor burns out, it should be rewound or replaced with a new one.

The pump hums, but does not spin:

The reasons for this pumping station malfunction are as follows:

• It happens that the pump spent the winter somewhere in a barn, and in the spring they took it out and tried to start it. But it starts to hum... Due to the fact that the pump for a long time remained without water and without movement, the pump impeller “glued” to the housing. You need to manually rotate the impeller from the back side, and then plug it into the network;
• the capacitor has failed (located in the branded engine box);
• It is necessary to check the voltage in the electrical network, perhaps it is simply too low.

That's all (or almost all) that can be said about malfunction of the pumping station for home water supply systems and about repairing a pumping station with your own hands.

Common important causes of frequent breakdowns

The pumping station has a certain configuration: a control unit consisting of a pressure gauge, a relay that regulates pressure, a pump, a hydraulic storage tank and other components. Repair of pumping stations involves replacing failed spare parts, changing electrical wiring, ensuring supply required quantity water. Causes of emergency:

• pump failure;
• there is no electricity or insufficient supply;
• there is not enough water supply, it is not in the system;
• damaged hydraulic tank for the pumping station;
• The automatic control sensor unit is faulty.

To identify inoperability conditions, it is first important to check the power consumption and the reliability of the circuit connection. At low voltage, a connection to a stabilizer is required. Then you need to turn off the power supply and rotate the shaft to eliminate possible wheel blocking. The next step is to check the operation of the starting device.

The pump may not supply water the following reasons: if its tightness is violated, if an air plug appears in the housing or along the overpass. Insufficient level water heights, low pressure, inconsistency, clogging or breakdown of pipelines and valves are factors that often cause work failure. Let's take a closer look at the methods for determining the main types of breakdowns and home renovation water pumps.

Repair the pumping station with your own hands only when the unit is completely de-energized. Be sure to remove the water, disconnect the pressure switch for the compressor, and the tank.

Brief analysis of the most popular problems and ways to solve them

The main problems are characterized by the following indicators: the pumping station does not turn on. The engine is running, but the pump does not operate, or water does not flow. The station's action is jerky. The pumping station does not turn off at all. Frequent switching from working mode to non-working mode.

When such violations occur, the pumping unit requires urgent restoration. Malfunctions of the pumping station are dangerous and can lead to a fire in the electrical wiring of the dacha building.

Knowing the operating principles of pumping stations, you can troubleshoot problems yourself

When turned on, the pump rotates, but no water enters the station system

What to do when incorrect operation is caused by other factors?

1. If there is no water in the pipeline or pump, work “dry”. Check the water level, top up the pump if necessary, or lower the leading hose down the well. To prevent insufficient water, the pipe is installed with an inclination to the surface of the intake site. Carefully monitor the filling of the well.
2. Solution to the problem when the integrity or tightness of the pipeline is compromised: it is necessary to patch the joints, gaps, and holes. All parts damaged by corrosion require immediate replacement.
3. If the hydraulic tank, pipeline, or check valve is contaminated with debris or sand, you need to clean them with a jet of water under pressure. The valve spring may break, requiring a new part.
4. When an air lock forms in the suction pipe, you need to fill, flood the internal space with water, and increase its pressure to eliminate the air.
5. For detailed cleaning, you will need to disassemble the pump, buy spare parts for the pumping station: housing, impeller, and replace them.

If the above measures do not bring positive result repair the water pump, replace it membrane tank better in a special workshop.

The pumping station operates intermittently and jerkily

Problems with frequent switching and uneven water supply are caused by a violation of the integrity of the housing or the internal membrane of the hydraulic tank. During such failures, the indicators of the pressure gauge device jump sharply up, then drop.

1. Carry out a test: press the tank nipple, if air comes out, the membrane is not damaged. When it breaks, a trickle of water will appear from the hole. It is necessary to disassemble the battery case, replace the old membrane with new part.
2. The problem of depressurization of the housing, caused by a crack or hole in the housing, is accompanied by a drop in pressure of the accumulator. You need to seal the hole, pump the missing air into the tank using a bicycle or car pump to the normal level (from 1.5 to 1.8 atm.).
3. Jerky water supply occurs when the integrity of the joints is damaged, there are cracks in the suction hose (pipeline), or the check valve is blocked. The reason is worn parts.

Disadvantages that arise due to depressurization can be easily eliminated during home repairs.

The pump does not turn on when starting

Possible malfunctions: fuse has blown, power supply has been turned off. Breakage, charring of insulation on the wire network. Destruction of relay contacts. The pump does not work if the motor shaft is jammed or the motor is burned out.

Necessary actions:

• check the power connection diagram of the station; eliminate cable breaks, replace the plug and fuse;
• make sure that the contacts inside the pressure switch are working properly;
• check the condition of the capacitor special device– tester;
• clean the pump;
• rotate the impeller to check the engine wedging.

You can check the engine unsticking by turning the impeller

To avoid engine combustion, do not turn on the pump again until fault factors have been eliminated. A sign of insulation breakdown or engine failure is a burning smell.

The pumping station may turn on, but does not rotate

If the pumping station has not been used for a long time, the impeller and pump housing may have become stuck. To eliminate the blocking process, you need to manually make several turns when turning off the power supply.

Another reason for the breakdown is that the capacitor has failed. To restore functionality, you will have to purchase a new replacement part for the device.

If you hear a humming sound when there is no rotation, the power supply may be insufficient. Solution to the problem: connecting the installation to the network through a voltage stabilizer.

It is adjusted using two nuts with springs located under the cover. Tightening one of them (large) determines the parameters of the lower and upper pressure of the relay, the other (small) determines the difference between the levels of the upper and lower indicators.

What is the operating principle of the relay when setting up?

1. Achieving the minimum value is carried out without water with the pump turned off and the tap open.
2. The pump uses a pressure gauge inside the hydraulic tank to reach normal pressure.
3. Unscrew the surface cap of the tank. The large spring is loosened, the pump is connected, and the nut is slowly tightened. Water station gaining pressure. When water enters, the pressure value is already equal to the parameters of the air indicator.
4. The process of regulating the differential begins: turn off the pump, measure the pressure of the relay. If the indicators are not satisfactory, tighten the small spring (or each one in turn). Then check the maximum value, bringing the pressure to normal.

A factor that causes incorrect operation of the relay when the station does not turn off is contamination of the contacts with deposits of metal salts if the source water is of poor quality.

The situation can be corrected by thoroughly cleaning the contacting surfaces with fine sandpaper. It is necessary to clear its water inlet from calcified or rusty iron plaque, garbage, sand.

A few notes about adjusting the pressure switch

If the values ​​of the pressure switch for the compressor in the hydraulic accumulator differ from the norm, the station will fail and the engine will burn out. In this case, the unit is not subject to warranty repair.

In addition, the moving components of the station wear out, which significantly changes the pressure, so after time it is necessary to adjust the indicators, repair the relay, and replace parts.

Initial factory setting of the relay in progress long-term use changes as the springs stretch.

It is safer to entrust the repair of a hydraulic accumulator, engine, tank to a specialist, since it is not easy to select the necessary spare parts for pumping stations, due to the exclusion of outdated models of devices from production.

Human need for water is very high. In the modern world it is needed almost everywhere. Therefore, there are many problems associated with water supply problems, with its correct and safe consumption.

Eternal problems with interruptions in water supply, the need to provide small farms with water, the need for reliable system Irrigation of vegetable gardens, orchards, increased pressure in the water supply system - these are just some of the problems that Russians face. All of them affect the desire of consumers to ensure constant access to water resources in any way.

Everyone overcomes current situations differently. However the best solution The current problem is considered to be drilling your own well. But in this case there is a need for all plumbing system in ensuring safety and control of its working pressure.

Automatic control unit "AQUAROBOT Turbipress", which appeared on the market relatively recently, helps in solving problems of protecting and automating the operation of electric pumps. Essentially, this is a small automation unit that combines a pressure switch and a fluid flow switch and turns the pump on or off under certain conditions. It is noteworthy that this automatic pump control unit is produced by a Russian manufacturer - Sabline Service LLC.

In order to decide on the use of this device, let's get acquainted with its functionality.

So, "AQUAROBOT" is capable of:

automatically turn off the pump when the pressure rises above the maximum setpoint and turn it on when the pressure drops below the minimum setpoint,

turn off the pump if there is no water flow, the pump is jammed (dry running protection),

after shutdown, due to detection of malfunctions, it is capable of conducting test runs after 5, 20, 60 minutes, and if water appears, it immediately switches the pump to operating mode.

The system can be used at reduced mains voltage (up to 170V). The maximum pump power is 2.2 kW, the maximum current is 20 A. “AQUAROBOT Turbipress” operates with single-phase submersible and surface pumps.

Pump control unit "AQUAROBOT Turbipress"

The pump control unit can be used equally by summer residents, owners of country houses, and various industrial enterprises and organizations.

On front side The device has two LEDs, red - “emergency”, green - “control”. Green lights up when the AQUAROBOT Turbipress device is turned on, and red lights up only in case of problems.

The "AQUAROBOT" consists of a device that interacts with a pressure sensor and a water flow switch. Installed parameters threshold pressure for pump activation/switching off are indicative for the microcontroller; by checking them with the pressure sensor data, the microcontroller sends a signal to turn the pump on/off.

It also interacts with the water flow sensor, the only difference is that in the latter case it only checks the system for the presence of water flow. If there is no water in the system, then "AQUAROBOT Turbipress" will turn off the pump and check the presence of water at certain intervals. If water does not appear within 24 hours, the device stops trying to turn on the pump and goes into emergency indication mode.

After eliminating the emergency situation with a lack of water in the water supply source, the device can be started manually by pressing one of the two buttons. After this, it returns to work with the settings previously installed on it.

For visual control of the pressure value, the device has a pressure gauge. The system also has three threaded pipes and cable entry/exit. All devices are enclosed in a plastic case, this gives the structure a harmonious appearance and design.

The connection of the AQUAROBOT turbipress pump control unit to the water supply system and to the electrical network must be carried out in accordance with the conditions and rules described in the documentation supplied with the device.

The pressure pipeline and water consumer must be installed in the system so that the direction of water flow corresponds to the arrow on the device body, i.e. from source to consumer. Both vertical and horizontal installation of the device is acceptable. All connections must be tight.

The electrical connection must be made according to the diagram attached to the documentation for the device. 2 cables are connected to the “aquabot” - one from the pump, the other from electrical network.

After connecting, you need to fill the system with water and configure the device. On the device you can set the lower and upper pressure, like a conventional pressure switch. The difference is that when performing these actions on other devices, for example, you need to tighten special nuts with the cover removed.

In this case, all settings are made using two buttons on the front panel of the “aquabot,” which is much more convenient and enjoyable. The programming process for setting the upper and lower pressure limits is not complicated, takes a few minutes and is described in sufficient detail in the operating instructions.

The automatic control unit for the AQUAROBOT Turbipress pump is very convenient. It is easy to install, easy to program, and we cannot forget about high reliability and quality of performance of the assigned task. Despite all of the above, the cost of the device is acceptable and amounts to no more than 3 thousand rubles.

Application area: for autonomous water supply of individual buildings, cottages, country houses, for organizing watering of vegetable gardens, garden plots, small farms.

The temperature of the pumped water is up to + 35°C, the total amount of mechanical impurities in the water is no more than 100 g/m³, the size of the impurities is no more than 1 mm.

Pumping stations for automatic water supply of the AQUAROBOT M series reliable in operation, simple and convenient to install, the pump can remain submerged in water for a long time. If desired, the pump can be easily removed from the water source and immersed in water again.

Submersible vibration pumps "MALYSH"- products highest quality. Subject to operating conditions, they can operate for several years, do not require lubrication or filling with water, and can be turned on immediately after immersion in water.

Design and principle of operation of the pumping station

Pumping station of the AQUAROBOT M series consists of the following main components: submersible electric pump, hydraulic accumulator, PM/5-3W devices(combining pressure switch, pressure gauge, fitting), check valve.
Submersible vibration electric pump “MALYSH” with a lower water intake consists of 3 main units: a yoke, a vibrator and a base. There are holes in the base covered with a rubber valve. A hose is attached to the outlet pipe using a clamp. Water is supplied from a pressure chamber limited by a rubber valve and piston. As a result of vibration vibrations electromagnetic drive the piston performs a reciprocating movement and pushes water out of the outlet pipe under pressure.

The hose connects the pump outlet pipe to the station control unit, which includes a hydraulic accumulator and a PM/5-3W device.

PM/5-3W device mounted directly on a gyroaccumulator of the appropriate volume. This device automatically turns on the pump when the pressure in the water supply network is below a threshold level (factory setting 1.5 atm) and turns off the pump when the pressure in the water supply network exceeds the upper threshold (factory setting 3 atm). The pump activation pressure is adjustable from 1 atm. up to 2.5 atm.

The pump shut-off pressure is adjustable from 1.8 atm. up to 4.5 atm.

Hydraulic accumulator maintains pressure in the water supply network within specified limits.

When the tap is open, water flows to the consumer from the hydraulic accumulator. As water from the accumulator is consumed, the pressure in the water supply network drops. When the pressure drops below the switching threshold, the control device turns on the pump. The pump supplies water to the consumer. We close the tap, the pump continues to work for some time, replenishing the water supply in the accumulator. As the accumulator fills, the pressure in the water supply network increases. When the pressure reaches the shutdown threshold, the control device turns off the pump.

If there is no water in the reservoir, thermal relay turns off the pump. This provides protection against dry running.

Hydraulic characteristics of pumping stations of the AQUAROBOT M series

Pumping stations of the AQUAROBOT M series are issued with hydraulic accumulators with a volume of 5 l or 20 l and an electric cable 16 m or 25 m long. In the station marking, the first number indicates the capacity of the hydraulic accumulator in liters, the second - the length of the cable in meters (“AQUAROBOT M 5 16” is a model with a hydraulic accumulator of 5 liters and a cable of 16 meters).

All models have built-in thermal protection of the pump motor.

Installation and commissioning

For commissioning pumping stations of the AQUAROBOT M series necessary:

1. Connect the station to the consumer’s water supply network. To do this, connect the outlet of the PM/5-3W device (internal thread “female” 1”) to the main pipe of the consumer’s water supply system, which unites all water collection points.

2. Connect the pump outlet to the check valve installed on the PM/5-3W device. For this purpose it is preferable to use flexible plastic hoses with a diameter of 20 mm. To make it easier to put on, the end of the hose can be softened hot water. Tighten the ends of the hose with clamps. To ensure a tight tightening, we recommend placing a strip cut from a hose.

The pump should only be connected to rigid pipes through a flexible hose at least 2 meters long!

3. Lower the pump into the water source. Refer to the Pump Installation Diagram for the reservoir.

The immersion depth of the pump should not exceed 3 meters. The vertical distance from the hydraulic accumulator to the water surface in the reservoir should not exceed 30 meters. The distance from the bottom of the reservoir should be at least 30 cm.

To mount the pump in a reservoir, tie the suspension (3) (included in the station kit) to the eye of the pump. Fasten the other end of the suspension to the crossbar (7), as shown in the diagram for installing the pump in a reservoir. When immersing the pump in the well, put the protective ring (9) on the pump. Fasten the cable (5), hose (6) and suspension with ties (2) at intervals of 1 - 2 meters;

4. Connect the station to a 220 V power source.

The station is ready for operation.

The pump should not operate for more than 2 hours continuously! After 2 hours of continuous work, take a break for 15 - 20 minutes.

Freezing of water in the station is not allowed! IN winter period If there is a danger of water freezing, it is necessary to completely drain the water from the station and the entire water supply system.
