Abstract

The invention relates to pumping engineering, can be used for pumping various liquids and improves productivity by accelerating the condensation process and reducing heat loss. The heat pump for pumping fluid contains a working chamber, an evaporation chamber, a condensing fluid injection nozzle, a piston device for active fluid injection with a float switch. The piston device is made dual-chamber with chambers 14, 17 and pistons 19, 20. Under the influence of hot gases, the liquid in the working chamber evaporates and begins to be displaced with increasing pressure, the pistons 19 and 20 rise and the chamber 14 is filled with liquid. When the fluid level in the working chamber 1 is lowered, the switch 9 is activated and the pistons 19 and 20 begin to move down, the condensing liquid is forced out of the chamber 14 into the working chamber and the condenser is vaporized in the latter, the pressure in the working chamber drops and it is filled with liquid. 2 Il.

Description

The invention relates to pumping equipment, can be used for pumping various liquids.

The aim of the invention is to increase productivity by speeding up the condensation process and reducing heat loss.

FIG. 1 shows a pump diagram; in fig. 2 - injection device and switch.

1 An e-pump for pumping fluid contains a working chamber 1, suction and discharge nozzles 2, 3 with check valves 4, 5, an evaporation chamber 6 in communication with the working chamber 1, a nozzle 7 of injection of condensing liquid, which is brought into the working chamber 1, a piston device 8 active fluid injection with a float switch 9 and leveling nozzles 10, 11. The working chamber 1 is made in the form of a vertical cylinder 12, the evaporation chamber 6 is in the form of a casing 13 installed in the upper part of the cylinder 12, and the piston device 8 is discharged A two-chamber chamber with an injection chamber 14, having check valves 15, 16, and a control chamber 17 installed above it. Cameras 14 and 17 contain pistons 19 and 20 connected by a rod 18 with a spring 21. The pressure chamber 14 is installed in the socket 7 injection and communicated with it through check valves 15,

16, the control chamber 17 communicates with the working chamber 1 and the suction nozzle 2 by means of leveling nozzles 10.11 through the float switch 9 installed in them 9. In the case 13 a reflector 22 of the condensing liquid jet is installed, B5 nozzle 10 has a cylinder 23 with a beveled end 24 associated with the spring-loaded lever 25. The switch 9 has a float 26.

The pump works as follows.

Under the influence of the heat of hot gases obtained, for example, by burning organic fuel, the liquid in the upper part of the cylinder 12 and the casing 13 boils, steam is formed, and the pressure in the working chamber 1 increases. The check valve 5 opens and the liquid pushed out by steam begins to be injected into the pipe 3. In this case, the pressure in the chamber 1 is transmitted through the equalizing pipe 10 and the cylinder 23 to the piston 20, giving it an upward movement.

The fluid pressure also acts on the piston 19, pushing it down, however, due to the difference in area, the pressure force on the piston 20 exceeds the force acting on the piston 19, and the pistons rise. In doing so, the spring 21 is compressed, the stock of mechanical energy being compressed. Under the piston 19, fluid is sucked from the cavity of cylinder 12 through valve 15. As the level of liquid in chamber 1 decreases, it leaves the heating zone and stops boiling. Further ejection of the liquid occurs due to the formation and overheating of steam during boiling of water remaining between the walls of the casing 13 and the cylinder 12.

The zone under the piston 20 is connected to the suction inlet 1 through the equalizing inlet 8 when the liquid level in the chamber 1 drops to such an extent that the float 26 is lowered.

The beveled cylinder 23 fixes the switch 9, the pressure under the piston 20

falls and it moves downwards, during which the fluid flows through the nozzle 7 into the chamber 1 and the vapor condenses in it, the pressure in the chamber 1 drops and it is filled with liquid through the valve 4.

Then the cycle of operation is repeated.
