Chinese wholesale Refrigeration Inverter Compressor - Air Source Water Heater Compressor. copeland scroll compressor 5/40 ton high temperature compressors , 380/60/3 R407c – Hengyi

Do you know why the compressor is damaged and how to prevent it from the source?
The liquid hammer is extremely destructive, and the vortex disk is very destructive for a short period of time.
will be shattered, the compression chamber will be destroyed, and the fragments may
may scratch the motor insulation and cause a short circuit
Excessive addition of refrigerant: causing a large amount of liquid back in the system (low-load cooling and low-temperature heating are more likely to occur in low-temperature environments)
Excessive addition of oil: lead to system oil shock (rarely): For high-pressure chamber compressors, too much lubricating oil will increase the rotational resistance of the motor, increase the input power, and worsen the heat dissipation of the motor; affecting the life of the motor.
3. The compressor burns out at high temperature
Performance failure phenomenon:
Exhaust or top temperature is too high;
The temperature of the press cavity is too high;
High pressure protection (when the system is blocked);
Current protection or circuit breaker tripping.
Failure cause analysis:
Insufficient addition of refrigerant or leakage of refrigerant: The temperature of the exhaust and return air is too high.
Refrigerant oil problem: refrigeration oil leakage or refrigeration oil quality problem.
▲High temperature leads to carbonization of compressor oil and aggravates wear
Dirty blockage or ice blockage of the system (ice blockage mainly refers to the return pipe): the exhaust or top temperature is too high.
The vacuum degree of the system is not enough: the compressor compresses the air, the pressure ratio is too large, and the temperature is too high.
