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.

What is the difference between an air pump and an air compressor

Many people think that an air compressor is actually an air pump. Generally speaking, the basic principle is still the same, but there are differences in the actual structure. According to relevant data, the intake and exhaust of the air compressor have valves.
