Abnormal sound of air compressor bearings is a common fault, which may cause damage to the machine and even lead to dangerous accidents. Therefore, it is very important to eliminate abnormal noise failures in time.
The following is an analysis of the reasons for the abnormal noise of the air compressor bearing:
The bearings of the air compressor need to be fully lubricated when they are working. If the lubrication is not good, the bearings will have abnormal noise. It may be caused by insufficient amount of lubricating oil, poor quality, blockage of oil circuit or excessive use time. Therefore, for the lubrication system, it is necessary to regularly check, replace the lubricating oil and clean the oil circuit.
After the bearing has been used for a period of time, abnormal noise will appear due to wear or damage. The wear of the bearing is related to the quality of the bearing, the use time, and the use environment. If the quality of the bearing is not satisfactory, the use time is too long or the use environment is harsh, it will cause bearing wear. Therefore, regular replacement of bearings is an effective measure to reduce abnormal noise.
Improper bearing installation
Improper installation of the bearing may cause damage to the internal structure of the bearing, resulting in abnormal noise. Therefore, when installing bearings, it should be carried out in accordance with the requirements of the manufacturer to avoid improper installation.
The bearing is too tight or too loose
Air compressor bearings that are too tight or too loose will cause abnormal noise. Too tight will cause excessive force on the bearing, which is easy to wear or damage; too loose will easily cause vibration and abnormal noise. Therefore, when installing the bearing, it is necessary to pay attention to the gap between the bearing and the bearing seat and control the tightness.
When the bearing is working, due to the heat generated by friction, it is easy to cause the bearing to overheat, resulting in abnormal noise. The cause of bearing overheating may be poor lubrication, bearing wear, too tight or too loose, etc. Therefore, when using an air compressor, it is necessary to pay attention to the temperature of the bearing and take timely measures to reduce the temperature of the bearing.
In short, for the analysis of the cause of the abnormal sound of the air compressor bearing, it is necessary to comprehensively consider the aspects of lubrication, bearing wear, improper installation, over-tightening or over-loosening, overheating, etc., and troubleshoot in time to ensure the normal operation of the machine.
