Abstract

A refrigeration compressor suction muffler includes a shell body and a shell cover; the inside of the shell body is provided with a partition plate, the partition plate extends from the front inner wall of the shell body to the rear inner wall of the shell body, and the partition divides a shell body cavity into a first silencing cavity and a second silencing cavity which communicate with each other; an air outlet nozzle extends from the left end of the outer wall of the front side of the shell body, the air outlet nozzle communicates with the second silencing cavity, and shell body positioning members are arranged on the outer wall of the shell and surrounds the periphery of the shell body at intervals; shell cover positioning members are arranged around the outer wall of the shell coverand at positions corresponding to the shell body positioning members at intervals, and the shell cover positioning members are matched with the shell body positioning members, an air inlet hole is formed in the right side wall of the shell cover, and the air inlet hole communicates with the first silencing cavity; and the refrigeration compressor suction muffler is characterized in that a shell body upper edge seal fitting groove is formed in the position of the peripheral edge of the outer wall of the shell cover side facing the shell body and the position corresponding to the upper edge of the shell body, and the shell body upper edge seal fitting groove is matched with the upper edge of the shell body in a sealing mode. According to the refrigeration compressor suction muffler, the noise is significantly reduced, the air suction resistance is decreased, and the volume is reduced to improve the 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...
