Fig.3 Schematic diagram of the pneumatic system

Low pressure block
The source of pressure in the block is a manual piston pump 1 with a spring for returning the pump rod to the working (uppermost) position. When the pump handle is pressed, pressurized air enters the pneumatic distributor 2, switching of which to one of its positions determines the creation of vacuum or excess pressure in the block. From the pneumatic distributor, excess (vacuum) pressure is supplied to the coupling 3, designed to connect the tested unit of the apparatus or adapter; pressure gauge 4, designed to control the pressure in the block and pneumatic distributor 5 with an adjustable throttle, designed to relieve pressure in the block.

Reduced pressure block
The reduced pressure from the air line of the breathing apparatus enters the unit through a quick-coupling connection 6. The value of the reduced pressure is controlled by a pressure gauge 7. The pressure in the unit is relieved by a pneumatic distributor 8.

7 TROUBLESHOOTING AND SOLUTIONS

Scroll possible faults and methods for their elimination are given in Table 4.

Table 4

For purchase of spare parts for the system, as well as for operation, Maintenance and repair, please contact the manufacturer or its service centers.

As Mr. Artamonov says, good day.
A lot has been written on a complete inventory, but if there is no time to read, then please.
1. Coordinate in advance the issue of time for inventory with the sales department, supply, and if the answer is storage, then with depositors (if this is not done, then they will not allow you to calmly conduct an inventory).
2. Issue an order (General Director) to conduct an inventory:
- commission
- what is checked
- when to start and when to end.
3. Prepare Inventory Sheets
-nomenclature
- number according to accounting data
- Quantity in stock (condition, marriage)
- surplus
-shortage
it is desirable to draw up inventory records by groups of goods, how they are stored and how they will be recalculated.
4. At the time of the inventory, the warehouse accountant and storekeepers give receipts that all invoices have been posted, all goods have been credited, if the assembled goods have not been shipped, then the order is canceled and the invoices are canceled.
5. The warehouse must be given at least 2-3 hours to prepare the goods for inventory: check that the goods are in their places, there are no more than one opened boxes (pallets, packs) of the same name, all receipts are placed in storage places.
6. During the inventory, the acceptance and shipment of goods is stopped (if there is an urgent need, then it is possible to unload the goods and set them aside, and posting is carried out after the inventory).
Do not forget to close the base so that no work is done in it.
7. Removal of residues is carried out on a commission basis (i.e., at least in the presence of 3 people), the person financially responsible shows where the goods are stored, but has no right to count.
For example, they count the goods for me and enter the data into the inventory of the warehouse accountant, while the storekeepers also count, but for themselves (if the numbers differ, then the storekeeper has the right to demand that the goods be recalculated), if all commission fees agree with the recalculation data, then the figure entered in the inventory.
After filling out each sheet of the statement, it is signed by all members of the commission, and subsequently certified with a seal.
If corrections are made in the statement, then they must also be certified with signatures and a seal.
8. After the end of the withdrawal of balances, all signed statements are handed over to the accounting department (I have the head of the paperwork department).
After that, the head of the document processing department and the warehouse database administrator, who is also the warehouse accountant, enter these data into 1C.
After that, they form the acts of writing off and posting, while identifying a possible regrading.
For each shortage or surplus, the financially responsible person (storekeeper) writes an explanation indicating the specific reasons why this happened.
Possible reasons sorters are identified, jointly, by 3 people - the head of the warehouse, the head of the clearance department and the administrator of the warehouse database (they do not report to each other, so the likelihood of collusion is quite small). Moreover, a control check of the results of the inventory is possible (of course, selective).
Managers of the supply department may be present at the inventory, who, with storekeepers, resolve issues on commercial acts (receipt) and have the right to transfer goods from condition to marriage.
9. If there are norms for the write-off of goods in the warehouse, the commission may propose to the director to write off part of the missing goods to the norms of natural loss.
10. Regrading can be accepted for offset for goods of the same group and must be the same in quantity.
11. Acts of write-off, posting and sorting are displayed with prices, if the difference is positive, then the goods simply accrue, if negative, then the difference is attributed to the material responsible person.
12.According to the results of the inventory, the database is being adjusted.

If the warehouse uses bar coding and there are readers, then the procedure changes somewhat, but purely technically.
Like that, good luck.

The device and principle of operation of the system

• System device.

The system (Fig. 1) consists of a portable plastic shockproof case 1 with a lid 2, a carrying handle 3, a lid lock 4, an eyelet for a transport seal 5, a compartment for adapters 6 and a latch button 7.

The headform (or test disc) is designed to hold the face piece in place when performing breathing apparatus tests.

The MG headform consists of a body 8 with a fitting 9 and a tube 10, through which the undermask space is connected to the system.

The test disk consists of a body 11 mounted on a bracket 12. On the body, a front disk 14 and a connecting nipple 15 with a tube 16 are fixed with a nut 13. The flywheel 17 and the pressure disk 18 mounted on it move along the threaded part of the body using the handle 19.

The device and principle of operation of the MGN headform are given in the instruction manual for the headform.

The control and measuring unit is located in the system case. The unit controls, instrumentation and devices for connecting to the unit (coupling and quick coupling) are placed on the control panel.

On the control panel (Fig. 2) there is a connecting sleeve 1 with a sealing gasket 2 and a plug 3, an excess (or vacuum) pressure release button 4, an excess-vacuum switch lever 5, a pressure gauge 6, a pump handle 7 with a latch 8, a button reduced pressure release 9, quick coupling (BRS) 10, reduced pressure gauge 11, stopwatch 12. A protective cap is put on the quick coupling.

• The principle of operation of the system.

The control and measuring unit of the system consists of two autonomous units (Fig. 3):

• low pressure block;
• reduced pressure block.

Low pressure block.

The source of pressure in the block is a manual piston pump 1 with a spring for returning the pump rod to the working (uppermost) position.

When the pump handle is pressed, pressurized air enters the pneumatic distributor 2, switching of which to one of its positions determines the creation of excess or vacuum pressure in the block. Excessive (vacuum) pressure is supplied from the pneumatic distributor to the coupling 3, to which the tested unit of the apparatus is connected directly or through an adapter, then to the pressure vacuum gauge 4, designed to control the pressure in the block and the pneumatic distributor 5, designed to relieve pressure in the block.

Reduced pressure block.

The reduced pressure from the airway system of the breathing apparatus enters the block through the quick coupling 6. The reduced pressure value is controlled by the pressure gauge 7.

The pressure in the block is relieved by the pneumatic distributor 8.

• Marking.

• The marking is on a label affixed to back wall corps.

The label says:

• product code;
• number of technical specifications;
• serial number of the product;
• date of manufacture (month and year).

The headform is marked on a plate attached to the body of the headform.

The test disc marking is on a plate attached to the bracket.

The headform (or test disc) marking contains:

• trademark of the manufacturer;
• name or code of the product;
• serial number of the product;
• date of manufacture (month and year).

INTENDED USE OF THE SYSTEM

Before using the system for its intended purpose, you must:

• prepare the system for work;
• check the system for leaks with the headform (or test disk) connected.

Preparing the system for work.

• Install the system and headform (or test disk) at the workplace, open the housing cover.

The initial position of the pointer of the manometer 6 (Fig. 2) must correspond to the position "0". If necessary, correct the initial position of the pointer using the adjusting screw, to do this, remove the plug from the glass of the pressure-vacuum gauge and set the position of the arrow through the hole in the glass (“bring it to zero”).

Start stopwatch 12 and test its operation by test run.

Bring the handle 7 of the pump into working position by turning the latch 8 in the direction of the arrow indicated on the panel.

Preparation of the MGN headform for connection to the system should be carried out according to the method described in the operation manual for the model.

• Checking the tightness of the system with a connected headform (or test disk) should be carried out sequentially with overpressure and vacuum pressure.

Install adapter No. 4 into sleeve 1 (Fig. 2) and connect the headform (or test disk) to it. Install plug No. 6 on the headform (or plug the hole in the body of the test disk).
