Repair method of screw refrigeration compressor wear

The application of screw refrigeration compressors is becoming more and more common, and some of them have entered a 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.
