Common faults and repairs of Electric Hight Pressure Washer

Common faults and repairs of Electric Hight Pressure Washer machine

Electric Hight Pressure Washers are widely used, not only in homes and commercial places, but also in industrial settings. However, if the Electric Hight Pressure Washer machine is used for a long time and lacks regular maintenance, it will cause abnormal squeaking, unstable pressure, abnormal noise, oil leakage, no water when firing, etc. Then how to repair the Electric Hight Pressure Washer machine if these faults occur? ? How to maintain the high pressure cleaning machine? Find out below.

1. Abnormal screams occur during operation.

The main reason for this phenomenon is that the motor bearings are short of oil. This is why we need to inject ordinary butter into the oil filling hole of the motor in time. This phenomenon does not happen often. We usually replenish the Electric Hight Pressure Washer machine during regular maintenance. That's it.

2. The pressure of the Electric Hight Pressure Washer machine is unstable

The unstable pressure of the Electric Hight Pressure Washer machine is mainly caused by air being sucked into the high-pressure water pump or the water inlet pipeline. At this time, you need to check whether the pressure of the water source is sufficient and whether the water inlet filter is clogged. If the water inlet filter is found to be clogged, remove the filter. Just remove the net and clean it with water.

3. The pressure decreases after running for a period of time

The pressure of the Electric Hight Pressure Washer machine will decrease after running for a period of time. For this phenomenon, you must first check whether the high-pressure nozzle of the cleaning machine is seriously worn. The high-pressure nozzle of ordinary pressure equipment will basically not show wear, because the high-pressure nozzle we equip is all Heat treated. The high-pressure nozzle of very high-pressure equipment is difficult to guarantee. Secondly, you need to check the sealing components inside the pressure regulating valve and water pump respectively.

4. The high-pressure water pump makes abnormal noises

Abnormal noise in the high-pressure water pump is caused by air being sucked into the water pump, or the flow valve spring is damaged, or the crankcase bearing is damaged. Once this phenomenon occurs, contact the manufacturer for assistance with repairs.

5. The crankcase lubricating oil becomes turbid or milky white

During regular maintenance of the Electric Hight Pressure Washer machine, observe through the window. If the crankcase lubricating oil becomes turbid or milky white, it means that the oil seal in the high-pressure water pump is not tightly sealed or has been damaged. If it is not replaced in time, the impurities in the water will seriously damage the crankshaft and The service life of the connecting rod, resulting in complete damage to the high-pressure water pump.

6. Oil leakage from the bottom of the high-pressure water pump

Oil leakage at the bottom of the high-pressure water pump is due to damage to the oil seal in the pump, which requires us to replace it in time. When the high-pressure water pump is running, the crankshaft and connecting rod are constantly making reciprocating motions. At this time, oil is required for lubrication and cooling, so The high-pressure water pump cannot lack lubricating oil.

7. The pressure of the pressure regulating valve is normal but no water comes out when the high-pressure water gun fires.

During use, it may happen that the pressure of the pressure regulating valve is normal but the high-pressure water gun does not discharge water or the water jet sprayed by the high-pressure nozzle is irregular and scattered. This indicates that the high-pressure nozzle is blocked by foreign matter and the high-pressure nozzle needs to be removed and cleaned.
