The role of high-pressure water pump and shut-off valve in water jet cleaning machine

　　High-pressure water jet pump is high-pressure water source of water jet cleaning machine. To continuously generate high-pressure water, a three-plunger is used, which is mainly composed of a shaft connecting rod and a plunger, and a high-pressure seal is installed in the booster chamber. Its plunger is specially treated and has high wear resistance.

　　Shut-off valve is manually adjusted and is mainly used for unloading, enabling motor to start with no load, and can also be used to adjust the system pressure and flow. If the connection method is changed, high-pressure water source of working system can also be disconnected.
