Air suction silencer for reciprocating compressor, and reciprocating compressor with air suction silencer

Abstract

The invention discloses an air suction silencer for a reciprocating compressor, and the reciprocating compressor with the air suction silencer. The air suction silencer for the reciprocating compressor comprises a lower shell, an upper shell and a coiled pipe assembly, wherein the lower shell is provided with an air suction pipe; the upper shell is arranged on the lower shell in a covering way; the upper shell and the lower shell are matched to define a holding space; the coiled pipe assembly is arranged in the holding space and divides the holding space into a first silencing chamber and a second silencing chamber; a first silencing expansion hole communicating with the first silencing chamber is formed in a part, located in the first silencing chamber, of the coiled pipe assembly; a second silencing expansion hole communicating with an inner cavity of the coiled pipe assembly is formed in a part, located in the second silencing chamber, of the coiled pipe assembly; the upper shell comprises an upper outer shell and an upper inner shell; the upper outer shell and the upper inner shell are connected through an upper connecting piece; the lower shell comprises a lower outer shell and a lower inner shell; and the lower outer shell and the lower inner shell are connected through a lower connecting piece. According to the air suction silencer for the reciprocating compressor provided by the invention, the upper shell and the lower shell are arranged to be of a double-layer structure, so that a better noise reduction effect can be favorably achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a suction muffler for a reciprocating compressor and a reciprocating compressor with the same. Background technique [0002] In related technologies, with the continuous development of social economy and science and technology, people's living standards are improved, and the awareness of environmental protection is also greatly enhanced. Refrigerators are essential household appliances in daily life, and people have higher and higher requirements for their performance. In addition to the important freezing capacity of refrigerators, their noise level is also one of the most critical indicators of refrigerators. The noise of refrigerators mainly comes from the compression of refrigerators. The noise of the refrigerator, as the "heart" of the refrigerator system, the refrigerator compressor has higher and higher requirements for its monomer performance, noise, and v...

AI Technical Summary

Problems solved by technology

[0003] At present, the common mufflers are complex in structure and cumbersome to manufacture, which increases the price of the compressor and even the entire refrigeration product. At the same time, most of the suction mufflers of the reciprocating piston compressor in the prior art are two-stage mufflers, because the muffler cavity is small and the compression ratio is limited. , so the traditional muffler has limited noise reduction
