Reason analysis of refrigeration compressor can not start or stop soon after start

1) First check the main circuit. Whether the power supply has power, whether the voltage is normal, whether the fuse has been blown due to starting overload, whether the air switch has tripped, whether the switch contacts are good, and whether the power supply is missing phase. Observe the voltmeter and ammeter when starting. When the small-scale refrigeration and air-conditioning equipment does not have an ammeter or electric meter, a multimeter or electric pen can be used to check the power supply. When the power supply voltage is too low, the compressor will not start.

Explanation of the excellent performance of each component of the screw chiller

　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.
