Compressor in the industrial chiller system produces wet stroke fault and troubleshooting

In the industrial chiller system, when the compressor sucks in wet steam, frost occurs on the cylinder wall, and the suction temperature and discharge temperature drop significantly. This is the wet stroke of the compressor, commonly known as frost.

Requirements for the use of freezing oil

Requirements for the use of freezing oil Due to the different use occasions and refrigerants, the choice of refrigeration oil for refrigeration equipment is also different. The requirements for freezing oil< are as follows: 1. Freezing point: The temperature at which the freezing oil is cooled to stop flowing under the experimental conditions is called the freezing point. The freezing point of the refrigeration oil used in refrigeration equipment should be as low as possible (such as R22 compressors

Working principle and usage method of motor bearing grease

Working principle and usage method of motor bearing grease The lubrication of the motor bearing relies on the lubricating oil that is precipitated when the three-dimensional fiber network structure in the grease is broken under the action of shear, forming a layer of lubricating film on the rotating elements of the bearing, the bearing seat and the bearing race for lubrication Effective.

The function and working principle of oil separator

The role of the oil separator in the chiller; In the vapor compression refrigeration system, the compressed ammonia vapor (or freon vapor) is in a high-pressure and high-temperature superheated state. Because of its fast flow rate and high temperature when it is discharged. Part of the lubricating oil on the cylinder wall is inevitably
