Wear prevention structure of the reciprocating compressor

摘要

Its components in spring support base wear prevention structure of the reciprocating compressor according to the present invention, the frame and the (93) is in contact with the front side of the resonance spring frequent contact occurs rear resonant spring (92), ( By forming a coating layer of Ni-P alloy material having high hardness in the inner peripheral wall of the integrated frame (91a, 92a), the cylinder and the spring supporting protrusions spring groove 91), the resonant spring (92 and 93 It can be rotated) while repeating compression / relaxation, it is possible to prevent the phenomenon that the spring support protrusion (91a, or 92a) a spring groove is worn, thereby improving the reliability of the compressor.
