This is the common cause of damage to scroll compressors...
Insufficient compressor oil and insufficient compressor lubrication.
When the compressor is in operation, a large amount of refrigerant gas is also taken away while entraining a small portion of the lubricating oil. Short-term shortage of oil in the compressor will cause abnormal wear of the relevant components inside the compressor, resulting in high vibration and noise. Long-term lack of oil will cause the internal components to overheat, resulting in bearing sintering, holding the shaft, compressor built-in protection, exhaust or Top temperature protection, overcurrent protection, power supply trip, abnormal compressor operation, high compressor cavity temperature, etc.
the reason:
1. The compressor starts and stops frequently for a long time.
2. The system contains air or moisture.
3. The system returns to the liquid or the refrigerant migrates to dilute the lubricating oil.
4. Compressor reversal (such as phase sequence error).
5, system refrigerant leakage makes the compressor lubricant less.
6. There are other chemical substances in the system, which cause the lubricating oil to deteriorate after chemical reaction with the lubricating oil.
