Inspiratory silencer of refrigeration compressor

Abstract

The utility model relates to a suction muffler of 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; A liquid discharge hole is opened on the bottom of the suction chamber of the shell and on the pipe wall of the air intake pipe of the shell cover. Advantages: The upper and lower anechoic chambers are enlarged, the path of the entire suction pipeline is long, the suction resistance of the suction pipeline is reduced, and it is beneficial to the efficient operation of the refrigeration compressor; it can protect the cylinder.

Description

technical field [0001] The invention belongs to the technical field of refrigeration compressor accessories, and in particular relates to a suction muffler of 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 current...

AI Technical Summary

Problems solved by technology

[0007]According to common knowledge, gas is compressible, but liquid is incompressible, so when liquid refrigerant enters the compressor cylinder in the refrigeration system and impacts the compressor valve plate , it will cause damage to the compressor valve plate and other components, and in severe cases, it will cause permanent damage to the compression part of the compressor.
