What is the hazard of high temperature to compressor motor and lubricating oil

The heat generated by the compressor during normal operation should not cause overheating. Normal motor heating, compression heat and friction heat have been carefully considered when designing the compressor, and corresponding cooling measures have been taken. However, in actual use, overheating of the motor due to problems such as over-range use, abnormal power supply, motor overload, refrigerant leakage, and too high condensing pressure are also common. Today, the editor focuses on telling you what high temperature does to compressor motors and lubricants:

　　1. Long-term overheating will not only reduce the insulation performance and reliability of the motor, shorten the life of the motor, but also reduce the lubricating ability of the lubricant, and even cause the carbonization and acid decomposition of the lubricant.

2. After the lubricating oil is carbonized, the lubricating ability will be greatly reduced, which will cause severe wear of the crankshaft, connecting rod, piston, piston ring, etc., and even stalling phenomena such as shaft holding, cylinder jam, and connecting rod breaking accidents caused by stalling .

　　3. Carbonized oil will also deposit carbon on the valve plate and valve plate, causing valve plate leakage and valve plate fracture.

　　4. The acidic substance in the lubricating oil will corrode the winding enameled wire and reduce the insulation performance of the winding.

　　 5. Acidified lubricants can also cause copper plating.

　　 Air-conditioning compressor manufacturers also remind everyone that high temperature is very harmful to the compressor motor and lubricating oil, so we must pay attention to correct and safe use in normal times.
