The heat generated during normal operation of the compressor should not cause overheating.Normal motor heating, compression heat and friction heat have been carefully considered in the design of the compressor, and the corresponding cooling measures.However, in actual use, motor high temperature, excessive exhaust temperature and overheating of lubricating oil and so on caused by problems such as out-of-range use, abnormal power supply, motor overload, refrigerant leakage and too high condensation pressure are also quite common.Today, I will mainly talk about the harm of high temperature on compressor motor and lubricating oil:
1. Prolonged overheating will not only reduce the insulation performance and reliability of the motor, shorten the service life of the motor, but also reduce the lubrication capacity of the lubricating oil, and even lead to carbonization and acid hydrolysis of the lubricating oil.
2. The lubrication capacity of the lubricating oil will be greatly reduced after carbonization, which will cause serious wear of crankshaft, connecting rod, piston, piston ring, etc. *** will appear blocking and rotating phenomena such as shaft holding, stuck cylinder and connecting rod breaking accident caused by blocking.
3. The carbonized oil will also form carbon on the valve disc and the valve plate, causing the valve disc to leak and fracture.
4. The acid in the lubricating oil will corrode the enameled wire of the winding and reduce the insulation performance of the winding.
5, acidizing lubricants can also cause copper plating.
Remind everyone high temperature on the compressor motor and lubricating oil is very big, so in peacetime must pay attention to the correct use, safe use.
