SU37995A1 - Hydraulic rod pump for deep wells or boreholes - Google Patents

Description

The author's certificate No. 37994 describes a pump with a hydraulic rod for deep wells or boreholes, equipped with a casing, which serves simultaneously as a pump cylinder and encloses a pump cylinder of a smaller diameter inside.

In the present invention applied; instead of a tubular hydraulic rod, a tube is closed on top, a JC bar or cable is suspended and contains water or compressed air, and, instead of a double action, a simple action pump, whose cylinder also communicates with the discharge pipe.

In the schematic drawing of FIG. 1 shows a general view of the proposed pump; FIG. 2 is a longitudinal section of the bottom of the pump in the ground; FIG. 3- the same, the upper part, located above the ground.

The proposed pump has a casing 1 which encloses the pump cylinder 7, the upper part of which is connected to the pipe 11, communicating at the top, through the holes 5, with the pressure

pipe 1, and the lower part is connected at point 10 with pipe 9, which is closed at the top, suspended from a stringer or rope. The piston 6, located in the cylinder 7, is on one side under the pressure of compressed air and water, enclosed in the pipe 9, and on the other, under the pressure of water flowing from the pipe 1 into the bollard 11 when moving to the left 13 B cylinder: simple action. The piston 6 is connected to the rod 4, the lower end of which is connected to the passage pistons 3 moving in the pipe 1, provided with an inlet valve 2 in the lower part, in the middle part, under the cylinder 7-outlet valve 8 and in the upper part above the cylinder 12-damper 14. A safety valve 15, mounted at the left end of the cylinder 12, is intended to prevent pipe rupture, possibly due to water penetrating one cylinder cavity into another.

When the pump piston 13 moves to the right (Fig. 1), the fluid in the pressure pipe 1 is filled to the left

the cavity of the cylinder 12, as a result of which the pressure of the liquid column above the piston decreases, and therefore, under the pressure of compressed air and water in the pipe 9, the pistons 3 and 6 move upwards, and the piston 6 displaces water from the c-allin 7 to the pipe 11, and the piston 3 displaces the pumped-out liquid, for example, oil, through the valve 8 to the open opening 14 in the upper part of the pipe 1 through the valve 14, and simultaneously with the "5" liquid is sucked through the valve 2. When the piston 13 moves back, the outlet 14 closes due to what the fluid for example is not The outlet from the left cavity of the cylinder 12 produces pressure on the water contained in the pipe II, under the action of which the piston 6, and with it the piston 3, moves downwards, and the water from the cylinder 7 slightly increases the pressure in the latter, will go into the pipe 9, and the oil at the lowest position of the piston 6, will go into the space above the piston 3.

The subject matter of the invention.

Modification of a pump with a hydraulic rod for deep wells or bore wells, characterized in the copyright certificate JMs 37994: a) instead of tubular 9-pipe hydraulic rod 9, closed on top, suspended from the rod or rope and enclosed; water and pressure air, b) pipes P opening up into the pressure pipe 1, ib) instead of a double-acting pump with a single-acting 12-pump cylinder, cylinder 12 of which also communicates with the vapor pipe 1. to the dependent author's certificate of A.A.
