SU32923A1 - Deep Well Pump - Google Patents

Description

In the proposed deep well pump equipped with a pneumatic rod, the pump inlet piston has a valve that is closed by means of a cam on a spring valve placed in the horizontal knee of the pneumatic rod and opening a hole in the knee.

The drawing shows a schematic vertical section of a pump for deep wells.

A pipe 7, which reaches to the water level, is inserted into a deep well. A piston valve 6 with a spring 5 is placed inside the knee; its opening 5. The valve b is provided with a cam 7 projecting through the slit 3, which keeps it from moving to the right. Above the knee - located through the piston P of the pump, having the shape of a glass. The rod 5 passes through a corresponding cutout in the wall of the piston 9. At the bottom of the piston there is a slit W located perpendicular to the orifice 5 of the knee and which can be covered along the entire length by the valve // hanging freely downwards.

At the exit to the surface of the earth, a pump 72 (of any system) is attached to the pipe 7 for pumping out air. Immediately there is a hole J3 for pouring out water; it is closed by a valve 7 opening outwards. The tube J of the pneumatic rod through the wall of the tube 7 is led outside and is connected to the compressed air tank, which is pumped by the pump 75. The compressed air inlet is controlled by the valve 76. The air pump 73 is pumped out of the tube 7. Water passing through valve 2, through the slit W in the piston I rises to a certain height. Then valve 76 opens. and the air rod tube 3 is filled with compressed air, which begins to press the spring valve 6. Under pressure, compressing the spring 8, the valve 6 moves to the left, and the cam 7 deflects the valve 77 to the left, which closes the slit tO of the flow piston. At this point, the valve 6 moves to the left so much that it has opened an opening 5, through which compressed air passes under the piston 9. Air pressure finally closes the valve 77 in the piston and the piston itself rises along with the water column above it to the top of the pipe. By the time the water reaches the top of the pipe, pumping of air from it stops. Water rising to the top of the pipe, its dove.

Lenpem opens valve 14 and pours out. The piston above the air pressure from below will rise up, squeezing the water out until it opens the lower edge of the opening 7J, through which the compressed air from the pipe / goes outside, by this time the valve 16 must be closed. A piston 9 remains in the cup, and in its wall there is a sheer slit on the side of the hole for water to flow out. When all of the compressed air exits outward {y, the valve // in the piston 9 is opened by the action of its own gravity, and the piston begins to descend. At the same time, the valve 6 under the action of the spring 8 begins to move to the right. In order to close the valve 5 at the very beginning, the air that is compressed in the tube 3 does not prevent the valve from moving further to the right, the air is released through

the second valve / 7 on the tube 3. Descending from a great height, the piston 9, due to friction against the pipe walls, cannot develop high speed, but still, to protect against this, there is a circumferential protrusion 75 in the tube / with a damping ring on it . After the piston is dropped onto the protrusion, the whole process begins again.

The subject matter of the invention.

A deep well pump equipped with a pneumatic rod, characterized by the use of a piston spring valve 6 placed in a horizontal knee of a pneumatic rod 6, which serves to open an opening 5 in that knee and is equipped with a cam 7, intended to close the valve // in a pump piston 9.
