What are the reasons for the high temperature of the air compressor

The air compressor is a transmission machine. If the equipment running at high speed is not properly lubricated or cooled, it will inevitably produce high temperature. Excessive temperature will cause changes in the physical coefficient values ​​of the rotor and bearing materials, and in severe cases, the entire main engine will bite.

Maintenance method for wear of refrigerator refrigeration compressor

　The application of screw refrigeration compressors is becoming more and more common, and some of them have entered the period of frequent failures. When the abrasion of the female and male rotors, body, and exhaust end seat of the refrigeration compressor reaches above 0.65rnm, vibration will occur when the refrigeration compressor is running, the sound is abnormal, the cooling capacity is reduced, and the compressor cannot work normally.
