The installation hole is provided with a piston body moving left and right, the left end of the piston body is provided with a left connecting rod which penetrates through the left end cover to stretch into the left pump shell, the right end of the piston body is provided with a right connecting rod which penetrates through the right end cover to stretch into the right pump shell, the left end of the left connecting rod is provided with a left piston, the right end of the right connecting rod is provided with a right piston, the left end of the left pump shell is provided with a left inlet one-way valve and a left outlet one-way valve, and the right end of the right pump shell is provided with a right inlet one-way valve and a right outlet one-way valve. The outer side face of the pump body is provided with a port P1, a port T1, a port P2 and a port T2. A control assembly is arranged in the installation hole. The high-pressurewater pump is simple in structure, small in size, simple in driving way and free of electric control.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and in particular relates to a high-pressure water pump. Background technique [0002] A 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 energy of the liquid. Positive displacement pumps use the volume change of their working chambers to transfer energy; reciprocating high-pressure water pumps are high-pressure water power source equipment commonly used in modern industries. 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 ...

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
