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.

Advantages of adding economizer to screw chiller

The temperature control range of the standard screw chiller is 3～35℃, and the efficiency is significantly reduced when operating under lower temperature conditions. In order to meet the temperature requirements of more industries for chillers, make the single-stage screw compressor work according to the two-stage refrigeration cycle and achieve the effect of energy saving, an economizer can be added to the unit.
