High pressure water pump

Abstract

The invention discloses a high pressure water pump. The high pressure water pump comprises a pump body, and a left end cover is fixedly installed at the left end of the pump body and a right end coveris fixedly installed at the right end of the pump body. A piston body is slidably connected into the pump body. A left pump case is fixedly installed on the left side of the left end cover, and a left sealing cover is fixedly installed at the left end of the left pump case. A right pump case is fixedly installed on the right side of the right end cover, and a right sealing cover is fixedly installed at the right end of the right pump case. A left connecting rod is fixedly installed at the left end of the piston body, and a right connecting rod is fixedly installed at the right end of the piston body. A left piston is arranged at the left end of the left connecting rod, and a right piston is arranged at the right end of the right connecting rod. A P oil port and a T oil port are formed inthe outer side surface of the pump body. The piston body is internally provided with a control component for controlling the piston body to move left and right in a mounting hole. The high pressure water pump is simple in structure and small in size, and can control the automatic back and forth movement of the piston body without electric control.

Description

Technical field [0001] The invention belongs to the technical field of water pumps, and specifically relates to a high-pressure water pump. Background technique [0002] A water pump is a machine that transports liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. Positive displacement pumps use changes in the volume of their working chambers to transfer energy; reciprocating high-pressure water pumps are commonly used high-pressure water power source equipment in modern industry. For a long time, the research and development of domestic reciprocating high-pressure water pumps has mainly focused on transforming foreign technology, digesting and absorbing on the basis of introducing foreign technology, but has not mastered the real core technology of high-pressure water pumps. The existing reciprocating high-pressure water pumps output pulses. Large, unstable, and easy to get stuck under severe worki...

AI Technical Summary

Problems solved by technology

For a long time, the research and development of domestic reciprocating high-pressure water pumps has been mainly based on the transformation of foreign technologies, and digestion and absorption have been carried out on the basis of the introduction of foreign technologies. However, the real core technology of high-pressure water pumps has not been mastered. The existing reciprocating high-pressure water pumps output pulses Large, unstable, and easy to get stuck under harsh working conditions, and the noise is loud during operation. In addition, most of the reversing valves that realize the reciprocating motion of the piston in the current reciprocating water pumps use electromagnetic reversing valves and displacement sensors to control the reversing valves. The sensor is controlled by the proximity switch, and the reversing is unstable and unreliable; the control circuit part of the reversing device is controlled by a circuit board, because the circuit board is a non-standard part, and it is difficult to manufacture and process, and it is very difficult to repair after damage ; If the existing reversing device is continuously energized for a long time, it is easy to damage small devices and cannot meet the requirements of long-term energization, which also affects production efficiency to a certain extent
