Abstract

The invention allows to increase the reliability of the pump. At the inlet section 10 of the U-shaped discharge pipe 5, the holes II are made, and its upper part 9 is located above the maximum level 8 of the liquid in the sleeve 3. Such an implementation simultaneously allows reducing the pump supply pulsation and controlling it. the work carried out the selection from the inner cavity of the sleeve made it about the gas without stopping the pump. 1 il.

Description

one

The invention relates to a pump engineering technique and is an improvement of the device according to the authors, no. 1 135918.

 . The aim of the invention is to increase the reliability of the pump, The drawing is a schematic diagram of the air cap of the suction pipe of the volumetric pump.

The air cap of the suction piping of the volumetric pump contains the upper 1 and lower 2 flanges between which the sleeve 3, made of transparent material, is fixed, the supply conduit 4 and the outlet 6 nozzles 6 and 7 of which are inserted into the inner strip of the sleeve 3 through the lower flange 2.

The end 6 of the inlet pipe 4 is located. In the sleeve 3 above the maximum level 8 of the liquid in it.

The end 7 of the outlet nozzle 5 is U-shaped, and its upper part 9 is located above the maximum level 8 of the liquid in the sleeve 3. In the inlet section 10 of the outlet nozzle 5, holes 1 are made at different levels.

The air cap of the suction pipe of the earth pump operates as follows.

In the process of pump operation (not shown, the pumped gas-rich; a given fluid flows through the air cap with simultaneous release of gas in the inner cavity of the sleeve 3.

When gas is removed from the pumped liquid, the liquid level in the sleeve 3 is lowered to the outlet port 5 located in the inlet section 10 of the discharge port 5, then through the discharge outlet 5 the gas is removed simultaneously with a portion of the liquid in the interior of the sleeve 3 .

The level 8 of the liquid inside the sleeve 3 decreases as long as the number above 8

15 holes 11 will not be sufficient

for complete removal of the released liquid when it is pumped gas.

of

The use of the invention makes it possible to simultaneously with the reduction of the pump supply pulsation and control over its operation, to take off gas from the internal cavity of the sleeve 3 without stopping the pump.
