Connecting method for connecting structure of reservoir and air conditioner compressor

Abstract

The invention discloses a connecting method for a connecting structure of a reservoir and an air conditioner compressor and belongs to the technical field of refrigeration parts. The connecting structure comprises a reservoir body and a compressor shell. The reservoir body is provided with a reservoir air outlet iron pipe. A second flange is welded to the reservoir air outlet iron pipe and is provided with a convex ring. A compressor cylinder is arranged in the compressor shell and is provided with an air inlet. A pump air suction pipe is arranged in the air inlet. The end of the pump air suction pipe is pressed into the air inlet of the compressor cylinder in an interference fit mode. The turned edge of the pump air suction pipe abuts against a first flange and the second flange. The first flange, the turned edge of the pump air suction pipe and the second flange can be combined through one time of welding. Meanwhile, the second flange is arranged as a welding clamping point, thus welding of the first flange and the second flange is convenient, the second flange is provided with the convex ring, electric currents can be focused conveniently during electric resistance welding, andwelding quality is improved.

Description

Technical field [0001] The invention belongs to the technical field of refrigeration accessories, and specifically relates to a connection method of a connection structure between a liquid accumulator and an air-conditioning compressor. Background technique [0002] Compressor is a fluid machine that elevates low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. The compressor shell is equipped with a cylinder. During operation, low-temperature and low-pressure refrigerant gas enters the cylinder from the intake pipe. After being compressed, the 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. Since the refrigerant cannot be completely vaporized in the evaporation stage during the operation of the system, in order to prevent the refrigerant from the evaporator from entering th...

AI Technical Summary

Problems solved by technology

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 cylinder and causing liquid shock, it is necessary to install a storage tank between the compressor and the evaporator. The liquid receiver, the cylinder and the liquid receiver are connected through the intake pipe. However, due to the structure, material and welding process of the connecting device, there are always problems in the assembly process of the liquid receiver and the compressor, such as complicated procedures, gas leakage caused by poor welding, etc. Various problems have caused great troubles to the industry

Moreover, the original connection method requires multiple weldings, which leads to high welding costs and high energy consumption.
