High-pressure cleaners are highly convenient industrial cleaning equipment. They are used for cleaning industrial equipment, removing paint and rust, and equipment maintenance. However, some minor issues may arise during the use of high-pressure cleaners. Common problems include:
1. The water discharge pressure is low; there are several ways to address this issue:
1) Check the filters. Small filters should be removed and cleaned, while large two-stage or three-stage filters should be tested or the filter bags inside should be replaced after exhausting the air inside the filter. This is to prevent filter blockage, which can lead to insufficient water intake.
2) Check whether the pressure regulating valve of the equipment is aging, and if so, replace the parts in time.
3) Check the inlet and outlet check valves and high-pressure seals of the high-pressure pump to see if there are any issues.
4) If none of the above issues are present, it is necessary to inspect the nozzle for any signs of wear, deformation, blockage, or other abnormalities.
2. The high-pressure pump produces abnormal noise; there are several ways to address this issue:
1) Noise is generated due to imbalance at the connection between the high-pressure pump and the power unit.
2) Air is being sucked into the high-pressure pump, or the spring of the inlet and outlet flow valves is damaged. Besides, the crankcase bearing should also be checked.
3) If the problem remains unresolved after checking these items, it is necessary to contact the manufacturer for repair.
