The pumping unit acts as follows. : Before starting the installation to work.

Ejectors 4 take the air out of the vacuum compartment 7 of the cartridge, and simultaneously ... 5.-5, and from the suction collection .t-, °, jl There is also a compartment of the cassette in the collector that accompanies the increase of the water levels in the needle filters 13. After the stock.

Introducing the design of the pumping unit of the camera (cassette) of the described device, mounted in its cteHKiT ejectors, allows not only to combine all the elements and devices of the pumping unit into a single unit, but also to reduce the width and length by about two times.

The gravitational outlet and the circulating tank were removed by the furnace through the furnace 14 and the socket 15. If the gravity flow was impossible, sSWIiaTpyeoK 15 should be connected with the plug and put the waste pipe 9 into the DL system and put the waste pipe 9 into the drainage pipe. ,; shutter10. The input of the discharge pipe into the work is carried out by opening the WeM valve 18 immediately after sending it, to the air supply system, to the cyclical selection system.

At the New EEC Level, the water in the circulating tank is float 11, control valve 10, holds: in its lowermost position,. The float rests on the lower abutment 19, and the rotary congestion completely covers the cross section of the discharge discharge pipe.

As the groundwater enters the circulating tank and the water level increases in it, the float begins to float and the valve rotates, which leads to a partial opening of the opening blocked by the valve and to the flow of part of the centrifugal injection pumped into the discharge pipe 9. The flow of water delivered by the pump to discharge, as the level of water in the circulating tank rises and the formation of the float increases. An increase in the water level in the circulation tank, while

and the float stops floating at the moment of equality between the flow of water withdrawn. from the ground (all of this flow enters the tank), and the flow rate dispensed along the pipeline; At the maximum calculated discharge flow rate, the water level in the circulation is. ;

The PS tank is up to the top mark, and: the runout floats to its extreme upper position, defined by the stop 20. The rotary shutter 10 opens the discharge

pipeline 9 completely. h ..

When reducing the flow rate of water taken by the installation from the soil, the process occurs in reverse order. Water level in circulating tank

The degree of opening is blocked (the 5th rotary shutter apertures decreases and a new dynamic equilibrium of the system arises only

after both flow rates — taken from the ground and discharged to the discharge line — become equal.

45 The use of a pumping unit is advisable in all cases of vacuum water heating, which is constrained by conditions of congestion, if it is not necessary, moreover, to release water taken from the ground to elevated elevations.
