Abstract

A suction muffler for a refrigeration compressor, comprising a housing, in which a partition is formed, the partition extends from the front inner wall of the housing to the rear inner wall of the housing, and is separated in the housing cavity by the partition The first and second mufflers communicate with each other, the left end of the front outer wall of the housing extends with an air outlet, and the air outlet communicates with the second muffler chamber, the outer wall of the housing and around the periphery of the housing form a shell in a spaced state. The body locating part; the shell cover, the shell locating part is formed around the outer wall and at the position corresponding to the shell locating part in a spaced state, the shell locating part cooperates with the shell locating part, and the right side wall of the shell cover is set into The air hole and the air inlet communicate with the first muffler chamber. Features: the edge of the outer wall on the side of the shell facing the shell and the position corresponding to the upper edge of the shell form a sealing fitting groove on the upper edge of the shell, and the shell The sealing fitting groove of the upper edge is sealingly matched with the upper edge of the casing. Significantly reduce noise; reduce suction resistance, reduce volume, and improve assembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of refrigeration compressor accessories, and in particular relates to a suction muffler for a refrigeration compressor. Background technique [0002] As known in the industry, a hermetic refrigeration compressor usually has a suction muffler installed inside it. When the refrigeration compressor is working, the cylinder sucks refrigerant gas through the suction muffler, and the suction muffler can weaken the compression The heating effect of the refrigerant when the internal heat of the machine is heated can also reduce the noise and vibration caused by the pressure pulsation during the flow of the refrigerant gas, thereby helping to reduce the operating noise of the compressor and effectively improving the working efficiency of the compressor. That is to improve the energy efficiency ratio (COP) of the refrigeration compressor. It can be seen from this that the suction muffler is indispensable and one of t...
