Description
Technical Field
The invention relates to the technical field of refrigeration compressors, in particular to a suction muffler with a gas-liquid separation function for a refrigerator refrigeration compressor.
Background
Noise is an important indicator of refrigerator compressor performance. In the structural assembly of the refrigerator compressor, the suction muffler is mainly used for controlling and reducing the transmission of noise in an air inlet channel caused by intermittent movement of a suction valve plate of the compressor, and has a flow guiding effect on refrigerant gas to be introduced into a compressor valve group, thereby achieving the purpose of improving the refrigerating capacity and efficiency of the compressor. Although the use of the suction muffler effectively reduces the airflow noise of the refrigerant gas, and enables the refrigerant sucked from the air suction pipe of the compressor to directly enter the air cylinder of the compressor through the flow guide pipe inserted in the muffler, thereby effectively improving the volumetric efficiency of the compressor, being an important technical means for improving the efficiency of the compressor, the suction muffler with the prior structure also has some negative effects, and mainly expressed in that: when the liquid return of the air suction pipe of the refrigerating system of the refrigerator is serious, part of refrigerant liquid and refrigerating oil can directly enter the air cylinder due to the fact that the refrigerant entering the air suction muffler from the air suction pipe does not have the effect of gas-liquid separation, not only is efficiency reduced, but also the valve plate is damaged, liquid impact and other reliability accidents are caused more seriously, and the reliability problem is more remarkable when the compressor is started or works in a severe environment.
Disclosure of Invention
The invention aims to solve the technical problem of providing a suction muffler with a gas-liquid separation function, which can effectively separate lubricating oil and refrigerant liquid in the sucked refrigerant and prevent the compressor from carrying out hydraulic compression or liquid impact while keeping the original muffler to have a silencing function on the refrigerant entering a compressor valve group.
In order to solve the technical problems, the air suction muffler with the air-liquid separation function comprises an air inlet pipe, an silencing cavity, an air-liquid separation cavity and a muffler head, wherein the air-liquid separation cavity is arranged between the air inlet pipe and the silencing cavity, an air-liquid separation mechanism is arranged in the air-liquid separation cavity, and a liquid discharge hole is formed in the bottom of the air-liquid separation cavity.
The suction muffler with the gas-liquid separation function further comprises a refrigerant inner insertion pipe, and the front end and the rear end of the refrigerant inner insertion pipe are respectively connected with the gas-liquid separation cavity and the muffler head.
The gas-liquid separation mechanism is a baffling separation type gas-liquid separation structure, a gravity sedimentation type gas-liquid separation structure, a centrifugal separation type gas-liquid separation structure, a filler separation type gas-liquid separation structure or a silk screen separation type gas-liquid separation structure.
The suction muffler with the gas-liquid separation function is characterized in that a through hole is formed in the bottom of the muffler cavity.
The suction muffler with the gas-liquid separation function is characterized in that the muffler cavity is positioned at the rear end of the gas-liquid separation cavity and the front end of the head of the muffler.
Due to the adoption of the technical structure, the muffler is internally provided with the gas-liquid separation cavity and the two independent cavities of the muffling cavity, and the gas-liquid separation mechanism is arranged in the gas-liquid separation cavity. When the refrigerant gas with liquid or oil components enters the muffler from the air suction pipe, the refrigerant gas firstly enters the gas-liquid separation cavity, the liquid in the refrigerant is separated through the gas-liquid separation mechanism, the gas-liquid separation mechanism can not influence the smooth passing of the refrigerant gas, the separated liquid or oil enters the compressor shell through the liquid discharge hole at the bottom of the separation cavity, and the refrigerant gas enters the muffler cavity and then enters the compressor valve group. Therefore, the invention not only maintains the original silencing effect of the silencer on the refrigerant entering the compressor valve group by carrying out gas-liquid separation on the refrigerant in the suction silencer, but also can effectively improve the efficiency and prevent the occurrence of quality accidents such as valve plate beating or liquid impact and the like caused by liquid entering the air cylinder.
