High-pressure water pump

Abstract

The invention belongs to the technical field of water pumps, and specifically discloses a high-pressure water pump. The high-pressure water pump comprises a shell body, a motor and ball valves, wherein the same crankshaft is rotationally connected to a position close to the side surface of the right side of the shell body, between the front sidewall and the rear sidewall; the motor is fixedly connected to the front end surface of the shell body; a guide cylinder is fixedly connected into the shell body; a piston is slidably connected into the guide cylinder; plug boxes are fixedly connected tothe position of the guide cylinder, of the side surface of the left side in the shell body; guide blocks are fixedly connected to positions corresponding to an upper direction and a lower direction of the guide cylinder, in the two plug boxes separately; and one ball valve is arranged above each guide block. Through the high-pressure water pump, continuous and stable water spray of the high-pressure water pump is realized, and the alternating change of a water spray pressure is avoided; and meanwhile, even if during low-speed rotation of the motor, a flow cutoff phenomenon is avoided, and through filtering for guided water, suction for lots of impurities in water into the high-pressure water pump is avoided, and the service life of the high-pressure water pump is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a high-pressure water pump. Background technique [0002] The most widely used high-pressure water pump is the miniature high-pressure water pump. Because of its high pressure, small size, easy to carry, and can be driven by a car battery, it is often used for cleaning, spraying, spraying, boosting, and pumping. [0003] The plunger-type high-pressure water pump is an important device of the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to achieve liquid suction and oil pressure. The plunger pump has a high rated pressure, It has the advantages of compact structure, high efficiency and convenient flow adjustment. [0004] According to CN205805846U, a purely mechanical reciprocating high-pressure plunger water pump has made technological innovations on the basis of traditional hydrau...

AI Technical Summary

Problems solved by technology

[0005] The plunger-type high-pressure water pump in the prior art adopts a synchronous plunger-type system, and realizes the synchronous change of the inner space of the corresponding guide cylinder through a single or multiple synchronously moving pistons, but the movement of a single piston or the synchronous movement of multiple pistons, The high-pressure pump internally sucks liquid and sprays liquid alternately. This reciprocating and alternating working principle has great disadvantages. When performing high-pressure liquid spraying, the pressure of the sprayed liquid will alternately change, that is, the spraying pressure is unstable. At the same time, because the plunger-type high-pressure water pump is equipped with a constantly moving piston, when the high-pressure water pump sucks in more impurities, these impurities will seriously affect the normal operation of the piston, accelerate the wear of the piston, and even cause damage to the piston.
