Gas absorbing silencer with gas-liquid separation function

Abstract

The invention discloses a gas absorbing silencer with a gas-liquid separation function. The gas absorbing silencer comprises a gas inlet pipe, a silencing cavity, a gas-liquid separation cavity, a refrigerant inner inserting pipe and a silencer head. The gas-liquid separation cavity is arranged between the gas inlet pipe and the silencing cavity. A gas-liquid separation mechanism is arranged in the gas-liquid separation cavity. The front end and the rear end of the refrigerant inner inserting pipe are connected with the gas-liquid separation cavity and the silencer head correspondingly. A liquid discharging hole is formed in the bottom of the gas-liquid separation cavity. A baffling separation type gas-liquid separation structure can be adopted in the gas-liquid separation mechanism. A refrigerant absorbed into the silencer is subjected to gas-liquid separation, the original function that the silencer can silence the refrigerant entering a compressor valve set is kept, meanwhile, lubricating oil and refrigerant liquid absorbed into the refrigerant can be effectively separated, and the situation that liquid enters an air cylinder, and the phenomenon of liquid compression or liquid impacts of a compressor happens is prevented.

Description

technical field [0001] The invention relates to the technical field of refrigeration compressors, in particular to a suction muffler with gas-liquid separation function for refrigerator refrigeration compressors. Background technique [0002] Noise is an important index to measure the performance of refrigerator compressor. In the structural components of the refrigerator compressor, the suction muffler is mainly used to control and reduce the noise caused by the intermittent movement of the compressor suction valve plate in the air intake passage, and to reduce the refrigerant gas that is about to enter the compressor valve group. It plays the role of diversion, so as to achieve the purpose of improving the cooling capacity and efficiency of the compressor. Although the use of the suction muffler is very effective in reducing the flow noise of the refrigerant gas, and makes the refrigerant sucked from the compressor suction pipe directly enter the compressor cylinder throu...

Problems solved by technology

Although the use of the suction muffler is very effective in reducing the flow noise of the refrigerant gas, and makes the refrigerant sucked from the compressor suction pipe directly enter the compressor cylinder through the muffler insert guide pipe, which effectively improves the compressor's performance. Volumetric efficiency is an important technical means to improve the efficiency of compressors, but the suction muffler of the existing structure also has some negative effects, mainly in: when the liquid return from the suction pipe of the refrigerator refrigeration system is serious, the suction pipe enters Since the refrigerant in the suction muffler does not have the effect of gas-liquid separation, part of the refrigerant liquid and refrigerated oil will directly enter the cylinder, which will not only reduce the efficiency, but also cause reliability accidents such as damage to the valve plate and liquid shock. This reliability problem is more prominent when the compressor starts up or works in a harsh environment
