Top cover of compressor

Abstract

The invention discloses a compressor top cover, which is characterized by the following: setting an outlet pipe on the central part of top cover vertically; fixing a mesh sieve filter device on the bottom of outlet pipe to remove coolant and lubricating oil, which reduces the danger of foreign material into circulation pipe path as well as improves the compressor cooling ability.

Description

technical field [0001] The invention relates to a compressor upper cover, in particular to a compressor upper cover equipped with a filter device. Background technique [0002] Generally speaking, a compressor is a device capable of compressing fluid, which usually consists of a sealed casing with an internal space, an electromechanical part installed in the sealed casing and providing driving force, and a compressor driven by the electromechanical part to compress the refrigerant. Composition of Compression Machinery Department. figure 1 It is a schematic diagram of the external structure of the compressor in the prior art. figure 2 for figure 1 Sectional view of the structure of the upper cover of the compressor in . Such as figure 1 , figure 2 As shown, this prior art compressor is internally provided with an electric mechanical part and a compression mechanical part not shown in the figure, and the lower part is provided with a suction pipe 1 which can suck the re...

AI Technical Summary

Problems solved by technology

When the compressor is running, the high-temperature and high-pressure gaseous refrigerant compressed by the compression mechanism can be discharged from the discharge pipe 2 into the circulation pipeline together with the lubricating oil inside the compressor. 3 The internal impurities may be mixed in the lubricating oil and flow into the circulation pipeline with the high-temperature and high-pressure refrigerant, which will reduce the refrigeration capacity of the compressor
