Problems solved by technology

[0002] The liquid receiver is an important part of the compressor, which plays the role of storage, gas-liquid separation, filtration, noise reduction and refrigerant buffering. As follows: The liquid receiver is installed in the air conditioner evaporator and compressor suction pipe, and is a protective part to prevent the liquid refrigerant from flowing into the compressor and causing liquid shock. During the operation of the air conditioning system, it is impossible to guarantee that the refrigerant can be completely vaporized ; That is, the refrigerant coming out of the evaporator will have liquid refrigerant entering the liquid receiver. Since the liquid refrigerant that is not vaporized is heavier than the gas itself, it will directly fall to the bottom of the liquid receiver cylinder, and the vaporized refrigerant will be Enter the compressor from the outlet of the accumulator
[0003] The traditional liquid reservoir is made of welding technology, which has poor sealing performance, while the joint of the liquid reservoir formed integrally by the spinning process is often relatively weak, which affects the service life of the liquid reservoir, and the traditional liquid outlet and liquid outlet The tubes are directly connected, and the sealing is poor. Therefore, it is an urgent problem to design a production process of the liquid reservoir that can solve the above problems.

Abstract

The invention discloses a production process for a liquid accumulator, and relates to the field of refrigeration equipment. A metal pipe is used as a blank, and the liquid accumulator is obtained through the steps of spin forming, drilled hole sealing, machining of liquid inlets and liquid outlets and pipe welding. According to the production process for the liquid accumulator, the liquid accumulator is integrally formed through the spinning process, and a plug is arranged at the weak position of a spinning connection opening, so that the airtightness of the liquid accumulator is greatly improved, and the service life of the liquid accumulator is greatly prolonged.
