The tightness of the transmission belt of the automobile air compressor also directly affects the life of the electromagnetic clutch. If the transmission belt is too loose, the electromagnetic clutch is prone to slip; if the transmission belt is too tight, the load on the electromagnetic clutch will increase. When the tightness of the transmission belt is not correct, the compressor will not work at light level, and the compressor will be damaged when it is heavy. When the drive belt is working, if the compressor pulley and the generator pulley are not in the same plane, it will reduce the life of the drive belt or compressor.
The repeated pull-in of the electromagnetic clutch will also cause abnormal noises in the compressor, such as insufficient power generation of the generator, high pressure of the air-conditioning system, or excessive engine load, which will cause the electromagnetic clutch to repeatedly pull in and close.
The gap between the electromagnetic clutch and the compressor mounting surface should have a certain gap between the compressor mounting surface of the electromagnetic clutch. If the gap is too large, the impact will also increase. If the gap is too small, the electromagnetic clutch will work with the electromagnetic clutch. Movement interference occurs between the compressor mounting surfaces, which is also a common cause of abnormal noise.
