Pay attention to keep the compressor lubricating oil clean

Pay attention to keep the compressor lubricating oil clean Why should we pay attention to keeping the compressor lubricating oil clean? This is because the dirty oil of the compressor or the deteriorated lubricating oil will cause a vicious cycle of accelerating the wear of the parts. Therefore, we should clean the lubricant oil of the compressor according to the following requirements:

How to select the thermal expansion valve？

1. The role and classification of expansion valves<br></br> Expansion valve is an important part of refrigeration system, generally installed between liquid storage cylinder and evaporator. The expansion valve causes the medium temperature and high pressure liquid refrigerant to become low temperature and low pressure wet vapor through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect.

Analysis of the cause of excessive suction temperature of compressor

Analysis of the cause of excessive suction temperature of compressor The high suction temperature is mainly due to the increase of superheat of suction. Note that high suction temperature does not mean high suction pressure, because the suction is superheated steam. Under normal circumstances, the compressor cylinder head should be half cold and half hot. If the suction temperature is too high, the cylinder head will all heat up.
