AI Technical Summary

Technical Problem

The existing compressor silence cover has two major problems in the exhaust design: vertical exhaust causes the refrigerant gas to flush the motor, affecting the rotor rotation and compression efficiency; while the side exhaust design increases production costs and the risk of foreign matter entry, and is poor in versatility.

Method used

A silence cover for compressors is designed, and the side exhaust design is adopted. The fixed part and projecting part are integrated into a molded fixed part and a protruding part to form a communication between the exhaust passage and the silence cavity, avoiding structural space limitations, improving production efficiency and reducing costs.

Benefits of technology

It effectively avoids the refrigerant gas erosion on the motor, improves the compression efficiency of the compressor, reduces the lubricant outflow, maintains sufficient lubricant in the compressor, and reduces production costs and improves production efficiency.

Abstract

The present invention relates to a silencer cover for a compressor and a compressor, wherein the silencer cover for a compressor is applied to a compressor pump body; the compressor pump body includes a bearing, and the bearing includes a bearing shank and a bearing flange; the silencer cover for the compressor includes a fixed portion and a protruding portion that are integrally processed and formed; the fixed portion is planar, and it abuts against the end face of the bearing flange; the protruding portion includes a first protruding portion and a second protruding portion, the first protruding portion and the outer peripheral surface of the bearing shank and the end face of the bearing flange are enclosed to form a silencer cavity, and the second protruding portion and the end face of the bearing flange are enclosed to form an exhaust passage parallel to the end face of the bearing flange. By adopting a side exhaust design, the problem of the high-temperature and high-pressure gas discharged in the vertical exhaust scheme affecting the remaining components of the compressor is avoided, and the outflow of lubricating oil can be reduced to keep the lubricating oil in the compressor sufficient, and the integrally processed design reduces the processing steps, which helps to improve production efficiency and reduce production costs.
