The difference between reciprocating and rotary compressors
1 reciprocating compressor - a displacement compressor whose compression element is a piston that is reciprocating in the cylinder.2. Rotary compressors, which belong to displacement compressors, are realized by the forced motion of rotating elements.
I don't know if you are talking about an air compressor. If it's an air compressor, I think I can give you a satisfactory answer.Is reciprocating, we usually saw outside that below a barrel, it is the kind of structure of the motor and the compressor, the principle is the working piston reciprocates in the cylinder, the reliability of the equipment is poor, big noise. In addition to small size, easy to move, basically no merit.Rotary, known as screw type, is to rely on screw rotation to work. The equipment is of high reliability and much higher than the reciprocating efficiency, and the failure rate is relatively low. That is, higher maintenance costs, more difficult maintenance, professional maintenance personnel must do.
Reciprocating compressors have compression and suction two strokes, the suction stroke is the refrigeration system is doing useless work.The suction and exhaust processes of the rotary compressor are completed simultaneously without any idle process. More efficient, more stable, lower noise.
