Pressure regulation plunger pump with water gun control function

Abstract

The invention relates to a pressure regulation plunger pump with a water gun control function. The plunger pump comprises a motor, a plunger pump body and a water gun, wherein the plunger pump body isdriven by the motor to operate, the water gun is connected with the plunger pump body through a high-pressure water pipe, the plunger pump body is provided with a general water inlet pipe, a return water inlet pipe, a water outlet pipe and a high-pressure water flow through cavity, the general water inlet pipe and the return water inlet pipe communicate with a cooling circulating cavity on the motor through a circulating device, one end of the water outlet pipe communicates with the high-pressure water flow through cavity, and the other end of the water outlet pipe communicates with a communicating pipe in the water gun through a high-pressure water pipe. The plunger pump has the advantages of being compact in structure and stable in performance and facilitating water flow control.

Description

technical field [0001] The invention belongs to the technical field of plunger pumps, in particular to a pressure-regulating plunger pump controlled by a water gun. Background technique [0002] A high-pressure cleaner is a machine that uses a power unit (motor, gasoline engine or diesel engine) to make a high-pressure plunger pump produce high-pressure water to wash the surface of an object, and the surface of the object is washed through a water gun connected to the high-pressure plunger pump. The power unit, high-pressure plunger pump and water gun in the existing high-pressure cleaner have the following defects: [0003] 1. The motors in the existing power units generally use fan blades for heat dissipation, and those that use fan blades for heat dissipation not only have slow heat dissipation, but also have high noise; there are also some water-cooled motors in the existing ones, but the structure of the existing water-cooled motors More complicated, the cooling system...

AI Technical Summary

Problems solved by technology

[0003] 1. The motors in the existing power units generally use fan blades for heat dissipation, and those that use fan blades for heat dissipation not only have slow heat dissipation, but also have high noise; there are also some water-cooled motors in the existing ones, but the structure of the existing water-cooled motors More complicated, the cooling system runs slower, and the function is simpler;

[0004] 2. The size and speed of the current control water gun are generally realized through the pressure regulating valve on the high-pressure plunger pump, which makes it very inconvenient to adjust the water gun in the process of flushing the surface of the object, and it cannot be adjusted in time. During the flushing process, the corresponding water flow size is adjusted;

[0005] 3. The high-pressure plunger pump used in the high-pressure cleaners on the market is an important device for distributing cleaning fluid. The position distribution of each valve in the pump body and the rationality of the structural design of the pump body itself can affect the entire high-pressure cleaner. The performance and voltage stabilization effect
