ChineseAutomotive air compressor manufacturers say that in fact, automotive air compressors are automotive compressors. As a high-speed rotating working part, the air compressor has a relatively high probability of failure, and abnormal noise is a common failure. There are many reasons for the abnormal noise of an air compressor. For example, the electromagnetic clutch of the air compressor is damaged, or the inside of the air compressor is severely worn, etc., which can cause abnormal noise.
1. The electromagnetic clutch of the air compressor is a common place where abnormal noise occurs. The compressor often runs from low speed to high speed under high load, so the requirements for the electromagnetic clutch are very high, and the installation position of the electromagnetic clutch is generally close to the ground, often It will come into contact with rainwater and mud, and when the bearings in the electromagnetic clutch are damaged, abnormal noises will occur.
2. The tightness of the air compressor transmission belt 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, the life of the drive belt or compressor will be reduced.
3. The repeated suction and closing of the electromagnetic clutch will also cause abnormal noise in the compressor, such as insufficient power generation of the generator, excessive pressure of the air conditioning system, or excessive engine load, which will cause the electromagnetic clutch to repeatedly pull in and close.
4. The gap between the electromagnetic clutch and the compressor mounting surface There should be 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 not work. There will be movement interference with the compressor mounting surface, which is also a common cause of abnormal noise.
5. The compressor needs reliable lubrication when working
