Problems solved by technology

This type of transmission has many parts, resulting in bulky, complex structure, and high failure rate; due to its structural characteristics, the output pressure of the reciprocating high-pressure water pump is zero at the moment of its reversing, which makes the output high pressure pulsate. It cannot be used in occasions requiring constant pressure

Abstract

The invention discloses a high-pressure water pump. A cylinder is included. At least three piston holes are sequentially formed in the right end of the cylinder with the axis of the cylinder as the center at equal intervals. A piston body is in sliding connection in each piston hole. A right end cover is fixedly arranged at the right end of the cylinder, water pumping assemblies are arranged in the right end cover, and each water pumping assembly is driven by the piston body corresponding to the water pumping assembly. A flow distribution shaft is arranged at the center position of the left end of the cylinder, a left end cover is fixedly arranged at the left end of the flow distribution shaft, and the flow distribution shaft is rotationally connected with a flow distribution disc. A firstflow distribution hole and a second flow distribution hole are formed in the right end face of the flow distribution disc. A cavity is formed in each piston hole, and an oil hole is formed in the left end face of the cylinder. The outer side of the cylinder is rotationally connected with a rotation barrel, and the left end of the rotation barrel is fixedly connected with the flow distribution disc. The integral design of the high-pressure water pump is highly integrated, space and components are saved, pressure output is free of pause, pulsation cannot be generated, and in addition, electriccontrol is not needed.

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] The high-pressure water pump is an important high-pressure water supply component widely used in water cutting, high-pressure cleaning and other fields. The traditional high-pressure pump uses an internal combustion engine or a motor to drive the pump body to operate, and its transmission mode mostly uses gear crankshaft transmission. This type of transmission has many parts, resulting in bulky, complex structure, and high failure rate; due to its structural characteristics, the output pressure of the reciprocating high-pressure water pump is zero at the moment of its reversing, which makes the output high pressure pulsate. It cannot be used in occasions requiring constant pressure. Contents of the invention [0003] The purpose of the present invention is to provide a high-pressure water pump, which not...
