The pressure washer cannot reach the rated pressure of the equipment

When the high-pressure cleaner is running, the working pressure cannot reach the rated pressure of the equipment, but the pressure can only be kept at the maximum and cannot rise. In this case, first check whether the hole of the high-pressure nozzle is matched or worn, if not, please replace it High pressure nozzle. Secondly, check whether the pressure regulating valve is adjusted to the correct position. If the pressure still does not rise after excluding these two conditions, you need to check the following:

1. Check whether the sealing surface of the pressure regulating valve or valve seat is worn, whether the O-ring is damaged, and whether the valve is stuck. If this is the case, please replace with a new pressure regulating valve (Note: If the pressure regulating valve is stuck, the phenomenon of "shut down the spray gun without unloading" will appear)

2. Check whether the water inlet and outlet valve components are damaged, mainly including O-ring damage, valve cover deformation or chipping, valve disc and valve seat wear, and valve disc and valve seat being sucked or raised by foreign matter. At this time, foreign objects need to be replaced or removed.

3. Check whether the water seal is worn. The main causes of water seal wear include: normal use wear, wear caused by poor water quality, long-term water shortage operation or too long to close the spray gun (usually close the spray gun for half an hour). If it is too high, it will wear out and need to be replaced at this time.
