How to solve the abnormal noise of high-pressure cleaner?

　　Common faults of high-pressure cleaners, water blasting and derusting cleaning machines, anti-corrosion, heat preservation and derusting equipment:

　　When high-pressure cleaner is running, high-pressure pipe vibrates violently, which is likely to be caused by disordered operation ofvalve, which needs to be re-pressurized to overcome it.

　　When high-pressure cleaner is running, if you hear an abnormal scream from it, it is likely that motor bearing lacks oil.

　　At this time, we only need to inject ordinary butter into the oil hole of motor to solve the problem. At the same time, we must also remember to replenish oil regularly in hydraulic pressure during daily maintenance.

　　High-pressure cleaner has a certain working pressure during operation, but rated pressure of equipment can never be adjusted. In this case, it is first necessary to judge whether the aperture of high-pressure nozzle matches.

　　If problem is still not resolved after replacing the nozzle, check the pressure regulator valve of pressure washer.

　　If fault persists under the premise of excluding these two situations, it means that seal assembly in the pump of high pressure washer is damaged or piston is damaged, and it is necessary to contact the manufacturer for assistance in maintenance.

　　Do not disassemble the equipment for maintenance without authorization, so as to avoid further deterioration of problem. When we regularly overhaul and maintain the high-pressure cleaner, we need to observe the color of crankcase lubricating oil through the window.

　　If it is found to become turbid or milky white, it means that oil seal in high-pressure water pump is not tight or has been damaged, and it must be stopped immediately for replacement.
