Abstract

The noise reducing apparatus of reciprocating compressor includes rack assembly set inside the casing, compression system for compressing refrigerant gas and lubricant oil supplying system. The lubricant oil supplying system lubricant oil pump installed below the rack assembly to pump lubricant oil from the casing bottom, the lubricant oil flow path on the rack assembly and connected to the lubricant oil pump to supply lubricant oil to between the cylinder and the piston and to recover lubricant oil to the casing bottom, and gas exhaust structure set on the rack assembly to separate the compressed gas from lubricant oil and exhaust compressed gas outside the compression system. The beneficial effects include simple structure, reliable performance, reduction in bubble noise and impact noise.

Description

technical field [0001] The invention relates to a reciprocating compressor, in particular to a noise reduction device for a reciprocating compressor. Background technique [0002] In general, reciprocating compressors include two types, one is a compressor that converts the rotational motion of a drive motor into a linear reciprocating motion of a piston to inhale and compress gas, and the other is a compressor that utilizes the linear reciprocating motion of a drive motor A compressor that drives the piston to make linear reciprocating motions to inhale and compress gas. [0003] As shown in Fig. 1 and Fig. 2, a kind of existing reciprocating compressor comprises: the housing 10 that a certain amount of lubricating oil is housed at the bottom and suction pipe SP and discharge pipe DP are housed, the bracket that is arranged in the housing 10 Component 20, the linear motor 30 fixed on the bracket component 20, the compression system 40 connected to the linear motor 30 and s...
