Abstract

The utility model relates to a suction muffler for a refrigeration compressor, which belongs to accessories of the refrigeration compressor. 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 pair of splints are formed in the anechoic chamber of the main shell, and a slot for inserting plates 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 transitional air pipe is formed in the anechoic chamber under the main shell It constitutes the ventilation pipe of the main shell; the inserting plate is formed in the sound-absorbing chamber of the shell cover, and the inserting plate is inserted into the slot of the inserting plate; The shell cover air outlet pipe cavity of the air outlet pipe communicates with the shell cover air intake cavity, and also communicates with the anechoic chamber under the shell cover. Advantages: The space of the upper and lower anechoic chambers is increased, and the path of the entire suction pipeline is long, which can reduce the suction resistance of the suction pipeline, which is conducive to the efficient operation of the refrigeration compressor.

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 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 curren...
