Shell for compressor and compressor

Abstract

The invention discloses a shell used for a compressor and the compressor. The shell used for the compressor comprises a shell body and a shell cover, the exhaust pipe assembly is fixed to the shell body and comprises a first pipe part and a second pipe part, the first pipe part is fixed to the shell body in a welded mode, the first pipe part is provided with an outer section part extending out of the shell body, the outer section part is fixed to the second pipe part in a welded mode, and the first pipe part and the shell body are made of iron. And the material of the second pipe part comprises copper. Therefore, the outer section part and the second pipe part are welded and fixed, and the outer section part and the shell body can be welded by adopting an electric resistance welding process, so that the production efficiency of the compressor can be improved, the welding reject ratio can be reduced, the use of brazing silver solder can be reduced, the production cost of the compressor can be reduced, and the production efficiency of the compressor can be improved. And the first pipe part is made of iron, so that the use of copper materials can be reduced, and the production cost of the compressor can be further reduced.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a shell for a compressor and a compressor with the shell for a compressor. Background technique [0002] In the related art, the casing of the compressor includes a casing body and an exhaust pipe assembly, the exhaust pipe assembly is installed on the casing body, the exhaust pipe assembly includes a first pipe portion and a second pipe portion, the casing body, the first The pipe part and the second pipe part are welded together simultaneously by brazing, wherein in order for the housing body, the first pipe part and the second pipe part to be welded together simultaneously by brazing, the end of the first pipe part does not extend beyond The exterior of the shell body has a high rate of defective brazing and low production efficiency, and silver solder is required for brazing, which increases the production cost of the compressor. At the same time, the first pipe part and the second...
