Structure classification of high pressure cleaner.

The high-pressure cleaning machine is mainly composed of high-pressure pump, safety valve, pressure regulating valve, foot control valve, high-pressure spray gun, high-pressure nozzle, power part, high-pressure pipeline, transmission device, pressure gauge, etc. , as follows:

1. high-pressure pump high-pressure pump is the core components of high-pressure cleaning machine, its role is to transform ordinary water into high-pressure low-velocity water, and the high-pressure water is conveyed to the high-pressure spray gun or the high-pressure nozzle through the high-pressure pipeline.

2.the role of the safety valve relief valve is when the pressure of high-pressure pump exceeds a predetermined value, the valve open, thus playing the role of pressure relief.

3. The pressure regulating valve is usually installed at the discharge end of the high-pressure pump. Its function is to expand the working pressure of the high-pressure cleaner automatically by controlling the bypass flow. When the pressure in the system exceeds the preset value, the valve will be partially opened. The higher the valve opening lift, the more water by-pass, high-pressure nozzle flow is smaller. The water that overflows through the valve can be directly returned to the pump or to the front tank. The pressure regulating valve can be divided into zero-setting pressure regulating valve and non-zero-setting pressure regulating valve. Return to zero pressure regulator is after the gun pump to the pressure regulator valve between the high-pressure pipeline pressure is“Zero”, between the valve to the high-pressure water gun pressure between the high-pressure pipeline to maintain high pressure. Non-return zero pressure regulating valve is shut, high-pressure water pump to the gun between the high, pressure pipeline is still high pressure. Now the majority of the use of zero pressure regulator valve. Control can be divided into manual and pneumatic two forms.

4.Foot control valve (foot valve) foot control valve functions similar to two types of high-pressure water gun, characterized by the operator can use the foot movement to control the high-pressure nozzle or nozzle.

5. The high-pressure spray gun is a common actuator, which is connected to the discharge end of the high-pressure pump through the high-pressure pipeline assembly.
