Street Washing Machine in the use of small pressure or no pressure is a common fault phenomenon, in order to help users to understand the cause of the fault, and timely help users to solve the problem, with the shortest time, teach everyone to deal with and troubleshoot, reduce the failure due to the failure of the operation of the pressure, especially sorted out several Street Washing Machine pressure or no pressure treatment methods, The details are as follows:

1. Low or no pressure of Street Washing Machine caused by insufficient water supply

Fault cause one: The water intake cannot meet the water required for the operation of the equipment, resulting in insufficient water supply, resulting in low or no pressure of the Street Washing Machine.

There are two kinds of treatment methods: (1) Use self-imbibition; ② Add booster pump.

Fault cause two: The lack of water supply caused by the filter plug caused by the unclean water source, resulting in low or no pressure of the Street Washing Machine.

There are two treatment methods: (1) increase the external filter; ② Replace clean water sources.

Two, high pressure pump internal parts caused by damage to the Street Washing Machine pressure is small or no pressure

Failure cause three: O-ring wear caused by water leakage caused by small or no pressure.

Solution: Replace the new O-ring.

Failure cause four: water seal damage causes low or no pressure of Street Washing Machine.

Treatment method: Replace the new water seal.

Fault cause five: normal wear of check valve causes low or no pressure of Street Washing Machine.

Solution: Replace a new check valve.

Failure cause six: check valve is pad by foreign matter, resulting in low or no pressure of Street Washing Machine.

Treatment method: Remove and clean the foreign body.

Failure cause seven: O-ring damage of pressure regulating valve causes low or no pressure of Street Washing Machine.

Solution: Replace the pressure regulating valve O-ring with a new one.

Failure cause eight: Pressure regulatig valve pin and seat surface wear cause Street Washing Machine pressure is small or no pressure.

Treatment: Replace the new pressure regulating valve pin and seat surface.

Failure reason nine: overflow valve O-ring damage caused by Street Washing Machine pressure is small or no pressure.

Treatment: Replace the relief valve O - ring.

Failure reason ten: relief valve damage caused by Street Washing Machinepressure is small or no pressure.

Treatment: Replace the relief valve with a new one.

The above is to summarize the Street Washing Machine in the use of no pressure or small pressure treatment method, you can control their own actual situation for troubleshooting.
