Suction muffler for compressor

Abstract

The utility model relates to a compressor suction muffler, which belongs to the accessories of refrigeration compressors. Including the main shell and the shell cover, the main shell has the main shell suction cavity, the main shell air inlet, the main shell muffler chamber, the main shell air outlet interface and the filter screen, the shell cover has the shell cover suction cavity and Shell cover anechoic chamber; features: a splint is formed in the anechoic chamber of the main shell, and an inserting plate slot is formed between the pair of splints, a transitional ventilation pipe and an air induction pipe are formed in the anechoic chamber on the main shell, and a main pipe is formed in the anechoic chamber under the main shell. Shell ventilation pipe; a plug-in plate is formed in the sound-absorbing chamber of the shell cover, a shell cover intake pipe is formed in the sound-absorbing chamber on the shell cover, and a shell cover air outlet pipe is formed in the sound-absorbing chamber under the shell cover. The body is composed of bottom mesh and side mesh. Advantages: The space of the upper and lower anechoic chambers is increased, the path of the entire suction line is long, the suction resistance of the suction line is reduced, and it is beneficial to the efficient operation of the refrigeration compressor; the filter area is significantly increased to avoid debris in the accumulation in the short term.

Description

technical field [0001] The invention belongs to the technical field of refrigeration compressor accessories, and in particular relates to a compressor suction muffler. Background technique [0002] As is well 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. It weakens the heating effect of the refrigerant when the compressor is internally heated, and also reduces 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 compressor's work. Efficiency, 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 the more important accessories of the current reciprocating herm...

Problems solved by technology

However, due to the unreasonable structure of the filter screen, it is flat and arranged on the outlet pipe in a tiled manner, so the effective filtering area is limited.

Since the fully enclosed refrigeration compressor cannot be opened for maintenance, after the suction muffler works for a certain period of time, debris gradually accumulates on the filter screen, resulting in an increase in the resistance of the suction line, thereby reducing the operating performance of the compressor
