The invention relates to pump construction, for volumetric pumps, and is intended for the addition of liquids to and from wells, especially for deep oil wells.

The purpose of the invention is to increase the reliability and performance of the pump.

The drawing shows a general layout of a volumetric pump.

The volumetric pump includes a housing 1, in the lower part of which there is an electrolytic cell consisting of conical electrodes 2, a central rod 3 and an insulating film 4. The electrolyzer is filled with an electrolyte, which uses a hydroxide solution, and is connected in a bipolar circuit to the source power supply (not shown).

An explosion-proof chamber 5, filled with distilled water, with a float-operated regulator 6, a vapor-outlet 7 and 8 non-return valves and openings 9 for water circulation, a driving chamber 10 with a spark plug 11, connected to a power source (. not shown), a safety valve 12 and a pressure sensor 13, a pump chamber 14 with a pressure 15 and a suction 16 valves made in the form of elastic plates. The pump 14 and the camera 10 10 are separated by a movable piston propellant 17, the course of which is limited by the latches 18.

For operation, the pump is immersed in the well below the fluid level.

The pump works as follows. When voltage is applied to the electrodes 2, electrolysis of water occurs, as a result of which a hydrogen-oxygen mixture is formed, which through gas-extracting holes made along the contour of the electrodes enters the upper part of the electrolyzer. When a certain pressure is reached, valves 7 and 8 open and the pelvis passes through the explosion-proof chamber 5 into the drive chamber 10. As soon as the pressure of the gas mixture in the drive chamber reaches the hydrostatic pressure in the well and the piston 17 begins to move upwards, the sensor 13 switches the voltage from the electrolyzer to ignition candle 11, as a result of which the gas mixture ignites in the drive chamber and explodes. As a result of the explosion of the gas mixture, the pressure in the drive chamber rises and the piston t7 begins to move upward, displacing the liquid from the pump chamber 14 through the discharge valve 15 into the pressure pipe.

As a result of the explosion of the gas mixture, water vapors are formed, which, cooling, again turn into water. As a result of condensation, the pressure in the drive chamber drops and the piston 17 moves down to the level of the retainers 18. At the same time, the pressure in the pump chamber decreases, the suction valve 16 opens and the pump chamber is filled with a well.

An electrical voltage is applied to the electrodes 2 again and the operating cycle repeats.

As a result of the explosion of the gas mixture, water accumulates in the lower part of the drive chamber 10 and enters the explosion-protective chamber 5 through the apertures 9. If the electrolyte level as a result of gas formation drops below the set point, the float of the regulator valve 6 opens the aperture 9 and water from the explosion of the protective chamber 5 enters the electrolyzer. As soon as the electrolyte level reaches the preset mark,

the float of the regulator 6 floats up again and stops the flow

water from the explosion-proof chamber 5.

In this way, automatic regulation of the liquid levels in the electrolyzer and in the explosion-proof chamber 5 is carried out.
