With the continuous development in recent years, the high pressure cleaning machine has been used more and more widely in our life and work. In the process of using the high pressure cleaning machine, we often encounter such and other problems. If there are some problems, we can follow the instructions. The instructions on the above will carry out simple handling by itself, but some faults can only be repaired under the guidance of professional maintenance personnel to prevent damage to the high-pressure cleaner. The following editor will introduce a kind of high-pressure cleaner that is often encountered. A cause of failure and its solution.

　　During our use, what should we do if we encounter a situation where the pressure of the pressure washer is very low or there is no pressure at all?

　　1. The high pressure cleaning machine cleans the water inlet filter and there is air. After cleaning the air in the water inlet filter, ensure that the standard outlet pressure is output.

　　2. The high-pressure nozzle of the high-pressure washer is severely worn. Excessive wear of the high-pressure nozzle will affect the water outlet pressure of the equipment, and the new nozzle should be replaced in time.

　　3, high pressure cleaning machine high and low pressure water seal and water inlet and outlet check valve leakage phenomenon, resulting in lower working pressure, these accessories should be replaced in time.

　　4. Insufficient inlet water flow of the connected equipment leads to insufficient water flow and insufficient output pressure. Sufficient inlet water flow should be supplied in time to solve the problem of reduced outlet pressure.

　　5. The internal failure of the high-pressure pump, the wearing of vulnerable parts, and the decrease of water flow; the internal pipeline of the equipment is blocked, and the water flow is too small, resulting in too low working pressure.

　　6. ​​The high-pressure pipe and the filter device are kinked, bent or damaged, which leads to poor water flow and insufficient water outlet pressure, which should be repaired in time.
