Adaptive automatic pumping station Unipump Aquarobot series QB is designed to feed clean water, which does not contain abrasive particles and fibrous inclusions, from shallow wells, wells and other water supply sources in automatic mode(turning on and off as the consumer consumes water). The station is equipped with an electronic unit that controls the operation of the pump in terms of flow and minimum pressure (Pmin), and also protects the pump from operation in “dry running” mode and other emergency situations (drop in mains voltage, incorrect installation, etc.). The pumping station is used for automatic water supply of houses, cottages and summer cottages, organization of irrigation systems, and increasing pressure in the water supply network.

The Unipump Aquarobot QB station is assembled on the basis of a QB series surface pump with a cast iron body. Brass impeller ensures long and reliable operation for many years.

Principle of operation Unipump stations Aquarobot QB is that when a water flow passes through the control unit at a speed above 2 l/min, or when the pressure drops below Pmin (1.5±0.3 bar), the pump turns on and pumps water continuously, creating pressure in the system , the value of which depends on the pump parameters. When the water flow stops or its speed decreases to 2 l/min, the pump automatically turns off with a thirty-second delay.

The Aquarobot pumping station adapts to the conditions of a specific water supply system and creates comfortable conditions water use for you and your household appliances. Whenever technical problems The aqua robot will simply turn off until it is eliminated technical faults in your highway.

Advantages of the Unipump Aquarobot QB pumping station:

Automatically turns off when there is no water in the water supply system.

Automatically switches off when the pump impeller becomes jammed.

Operates stably when the mains voltage drops to 120 V.

Automatically turns off if there is no air pressure in the accumulator.

Automatically turns off when water leaks from the water supply system, if the flow rate is no more than 2 l/min.

Adaptively maintains pressure in the water supply system, which significantly increases the service life of the pump.

Operates stably at a critical suction depth of 8 meters.

Automatically turns off if the station is incorrectly connected to the water supply source.

In the event of an emergency shutdown of the pumping station, it is necessary to eliminate the cause and restart it.

Attention. The use of the station in pressure boosting systems is not allowed if the pressure created by the pump, combined with the main pressure, is higher than or close to 6 bar.

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 - trademark AquaRobot – 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, which can only happen:

• 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 the 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.
