It is well known that the exhaust gas temperature is a parameter that must be strictly controlled during operation of a refrigeration compressor of a cryogenic refrigeration unit. If the exhaust temperature of the compressor is too high, it will directly cause overheating and affect the operation of the chiller. Today, we will talk about some of the effects of excessively high exhaust temperatures in the operation of cryogenic refrigeration unit compressors.
1. Directly lead to a decrease in the working efficiency of the condenser.
Because the exhaust temperature of the refrigeration compressor of the cryogenic refrigeration unit is high, the work efficiency will be reduced. In addition, after the high temperature gas is discharged to the condenser, the condenser cannot completely cool the refrigerant, and when it is serious, the liquid will be accumulated. For a long time, the condenser works. The efficiency will naturally drop, which will affect the operation of the whole machine.
2. The gas transmission coefficient of the compressor is reduced, the shaft power is increased, and the viscosity of the lubricating oil is lowered. As a result, abnormal wear occurs in the bearing and the cylinder and the piston ring. Even worse, it can cause failure of burning bearings or cylinders.
3. The exhaust temperature of the refrigeration compressor of the cryogenic refrigeration unit is too high, which is a kind of loss to the compressor itself, which will directly affect the service life. Because the chemical reaction rate is increased by the increase of the temperature of the old age, in general, the temperature of the electrical insulation material rises by 10 ° C, then the service life will be reduced, especially the fully enclosed compressor is more important.
4. The lubricating oil and the refrigerant are thermally decomposed under the catalysis of the metal, and produce an acid substance, free carbon and moisture which are harmful to the compressor. If free carbon is deposited on the exhaust valve, it will not only destroy its tightness, but also increase the flow resistance. If the stripped carbon residue is taken out of the compressor, it will block the capillary (or expansion valve) and dry the filter. The acid substances corrode the components of the refrigeration system of the cryogenic refrigeration unit and the electrical insulation materials.
The effect of excessive temperature of the refrigeration compressor of the cryogenic refrigeration unit is still very serious. Therefore, we need to arrange professional operators to check the refrigeration unit regularly, find problems in time, solve problems, and help the refrigeration unit to play a greater role. Provides stable industrial chilled water for equipment.
