Assembling method for liquid storage device and compressor

Abstract

The invention relates to the technical field of compressors, in particular to an assembling method for a liquid storage device and a compressor. The assembling method comprises the steps that a through hole is formed in a side surface of a housing; a flange is formed at the edge of the through hole; the diameter of the through hole is greater than the outer diameter of an air inlet pipe; an air cylinder is placed in the housing; a first end of the air inlet pipe penetrates the through hole and is pressed into an air inlet of the air cylinder; a seal groove is formed at the air inlet and internally provided with a seal ring; the seal ring is connected with a side wall of the air inlet pipe in a sleeving manner; and the flange is welded with the air inlet pipe along the excircle of the air inlet pipe after the air cylinder is fixed in the housing. According to the assembling method, the air inlet pipe is connected with the housing directly, refrigerant gas enters the air cylinder directly through the air inlet pipe and passes through few parts; and the seal ring is arranged between the air inlet pipe and the air inlet of the air cylinder, so that leakage is avoided. As the air inlet pipe is fixed by the flange, the structure is simple; the assembling is convenient; welding positions are few; the welding material consumption and the labor intensity can be reduced; and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an assembly method of a liquid accumulator and a compressor. Background technique [0002] The compressor is a fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. There is a cylinder inside the shell of the compressor. When working, the low-temperature and low-pressure refrigerant gas enters the cylinder from the intake pipe, and the cylinder After it is compressed, high-temperature and high-pressure refrigerant gas is discharged from the exhaust pipe to provide power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression→condensation→expansion→evaporation. During the operation of the system, it is impossible to guarantee that the refrigerant can be completely vaporized during the evaporation stage. In order to avoid the liquid refrigerant coming out of the evaporator from entering the cy...
