Reasons for high temperature of refrigeration compressor discharge (Technology Sharing)

Reasons for high temperature of refrigeration compressor discharge (Technology Sharing) The refrigeration compressor is the core and heart of the refrigeration system. The capacity and characteristics of the compressor lead to the capacity and characteristics of the refrigeration system. In a sense, the design and matching of the refrigeration system is to reflect the capacity of the compressor. Therefore, the refrigeration industry of all countries in the world has invested a lot of energy in the research of refrigeration compressors, and new research directions and research results are constantly emerging. The technology and performance levels of compressors are changing rapidly. There are many types of compressors. According to different working principles, refrigeration compressors can be divided into fixed displacement compressors and variable displacement compressors.    Reasons for the discharge temperature of refrigeration compressor being too high    ⑴ The clearance in the compressor cylinder is too large.   ⑵ The compressor suction and discharge valve and piston ring are damaged.   ⑶ The compressor safety bypass valve is leaking.   ⑷ The compressor suction temperature is too high.   ⑸ The lubricant in the compressor cylinder is interrupted.   ⑹ The compressor suction pressure is too low or the suction valve is too small.   ⑺ The compressor suction pipe or filter is clogged, and the heat insulation layer is damaged.   ⑻ The resistance in the compressor return pipe is too large, and the gas flow rate is slow to easily cause overheating, which causes the exhaust temperature to increase.   ⑼ The condensing pressure of the refrigeration compressor is too high; there is oil or scale in the condenser.   ⑽ The amount of water in the cooling jacket of the compressor cylinder head is insufficient; or the temperature of the cooling water is too high.   ⑾ The cooling capacity of the compressor is less than the capacity of the warehouse equipment, such as the evaporation area is too large.   ⑿ Excessive resistance in the exhaust pipe of the compressor.   ⒀ The throttle valve of the refrigeration compressor is too open or blocked.   ⒁ The compressor itself has poor efficiency.   ⒂The installation height of ammonia separator i
