SUPPORT DEVICE OF RECIPROCATING COMPRESSOR FOR REDUCING VIBRATION OF THE COMPRESSOR WITHOUT FIXING COMPRESSOR BODY TO CASING

摘要

PURPOSE: A support device of a reciprocating compressor is provided to reduce vibration of the compressor without fixing a compressor body to a casing. CONSTITUTION: A support device of a reciprocating compressor comprises a reciprocating motor(30) fixed to frames(21,22,23) in a casing to enable an operator to reciprocate rectilinearly; a compression unit(40) having a piston combined to the operator of the reciprocating motor; a resonant spring unit(50) elastically supporting the piston and the operator among the frames to enable the piston to move rectilinearly together with the operator; and a support spring unit(100). The piston is combined to the operator of the reciprocating motor, to suck and compress refrigerant gas while reciprocating rectilinearly in a cylinder fixed to the frames. The support spring unit comprises first support springs(110) having one ends fixed to the frames; second springs(120) having one ends fixed to the casing; and a mass(130) fixing both ends of the first and second support springs to the upper and lower sides and vibrating between the first and second support springs.
