The heat of the compressor during normal operation should not cause overheating. Normal motor heating, compression heat and friction heat have been carefully considered in the design of the compressor, and there are corresponding cooling measures. However, in the actual use, due to over-range use, abnormal power supply, motor overload, refrigerant leakage, condensation pressure is too high caused by the motor high temperature, exhaust temperature is too high, oil coke paste and other overheating phenomenon is also more common. Today small series focus on the high temperature to the compressor motor and lubricating oil what harm:

1, a long time overheating, not only reduce the insulation performance and reliability of the motor, shorten the life of the motor, but also reduce the lubrication ability of lubricating oil, and even *** cause carbonization and acid decomposition of lubricating oil.

2, lubricating oil carbonization lubrication ability will be greatly reduced, will cause the crankshaft, connecting rod, piston, piston ring and other serious wear, and even *** will appear holding shaft, stuck cylinder and other blocking rotation phenomenon and by blocking caused by the breaking of connecting rod.

3, carbonized oil will also be in the valve plate and valve plate carbon, causing valve plate leakage and fracture.

4, the acid in the lubricating oil will corrosion winding enameled wire, reduce the insulation performance of the winding.

5, acidizing lubricating oil will also cause copper plating phenomenon.

Remind everyone that high temperature on the compressor motor and lubricating oil is very big harm, so in peacetime must pay attention to the correct use, safe use.
