Why does the car washer water pump make noise


There will be noise in the operation of mechanical equipment. This is a problem of sound size. Some large ones will generate noise. The car washer pump is not a high-power mechanical equipment. If the noise is too loud during operation, what causes it?

The running noise of the car washer itself, because the running of the water pump will cause the vibration of the pipeline and the noise of the electrical transformer, all of which will occur during the running, but the problem is the size of the sound. If there is too much business, you need to stop the machine for inspection, find out what the specific problem is, and then solve it.

There are many factors that cause the noise of the car washer water pump, mainly including aerodynamic noise, mechanical noise and electromagnetic noise. When the motor is working, because the air flow noise of the cooling air and the aerodynamics formed by the high speed rotation of the fan upgrade early, the electromagnetic noise is mainly caused by the alternating electromagnetic gravity between the stator and the rotor. If you know the cause of the noise, you can find a solution.
