High pressure cleaning pump

Abstract

The invention relates to a high pressure cleaning pump. The high pressure cleaning pump comprises a motor, a cover connected with an upper end cover of the motor, an inclined disc, a plane bearing, four stand columns, four plunger pistons, stopping rings, four compression springs, a connecting base, lower channels, four upper channels and a high pressure outlet; a water inlet cavity is defined bythe upper end cover and the cover, the inclined disc is arranged in the water inlet cavity and is connected with an output shaft of the motor, a tightening ring of the plane bearing is connected withthe upper end of the inclined disc, the four stand columns are arranged on the top face of the water inlet cavity, the four plunger pistons penetrate the stand columns in a one-to-one correspondence manner, and the lower ends of the plunger pistons are provided with spherical surfaces pressing the upper end of a loose ring of the plane bearing; the stopping rings are arranged at the lower ends ofthe side peripheries of the plunger pistons, the stand columns are sleeved with the four compression springs in a one-to-one correspondence manner, the lower end of the connecting base is provided with four containing holes and is connected with the upper end of the cover, the lower channels are arranged in the plunger pistons, are connected with the water inlet cavity and the containing hole, andare provided with lower one-way valves, and one ends of the four upper channels are connected with the top faces of the containing holes in a one-to-one correspondence manner and are provided with upper one-way valves; and the high pressure outlet is arranged at the upper end of the connecting base and is communicated with the other ends of the upper channels. During motion, side direction forceborne by the pushing ends of the plunger pistons is small, and motion is stable.

Description

technical field [0001] The invention relates to the field of cleaning equipment, in particular to a high-pressure cleaning pump. Background technique [0002] High-pressure cleaning pumps are often used in high-pressure cleaning machines; the invention of Chinese patent application number CN20210251087.0 discloses a crankshaft-type high-pressure cleaning pump, including a box body, a crankshaft connected to power, a connecting rod, a plunger, a pump body, and a water inlet joint , pressure regulating and unloading valve, high-pressure water outlet joint, the pump body is provided with a low-pressure chamber, an exchange chamber and a high-pressure chamber, the plunger is connected to the exchange chamber, the water inlet joint is connected to the low-pressure chamber, and the low-pressure chamber and the exchange chamber A water inlet one-way valve is installed between them, and a water outlet one-way valve is installed between the exchange chamber and the high-pressure cham...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the current crankshaft type high-pressure cleaning pump that the pushing end of the plunger and the connecting rod is subjected to a relatively large lateral force and the movement is not stable enough, and to provide a method for the pushing end of the plunger to be moved. Low side force, smooth motion high pressure washer pump
