Embodiment Construction

[0015] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:

[0016] Such as image 3 shown. The high-strength compressor shell structure disclosed in this embodiment is directly improved on the existing compressor shell. The wall thickness is consistent with that of the shell of the existing compressor using R22 refrigerant.

[0017] In order to make the casing 1 with the above-mentioned wall thickness use R410A refrigerant, a reinforcing ring 2 is encased in the middle of the casing 1 in the circumferential direction. The reinforcing ring 2 is a circular ring made of metal with high strength. It is tightly hooped on the outer wall of the shell 1 through thermal deformation, that is, the reinforcing ring 2 is heated and expanded, and its inner diameter is enlarged. The reinforcing ring 2 is firmly sleeved on the outer periphery of ...

Abstract

A high-strength compressor shell structure includes a compressor shell on which a reinforcing component is arranged. The reinforcing part is a reinforcing ring, and the reinforcing ring is hooped around the outer periphery of the shell in the circumferential direction. The shell structure of the high-strength compressor disclosed by the present invention can be directly improved on the existing compressor using R22 refrigerant to meet the requirements, the modification is convenient, the cost is low, and there is no need to replace the compressor with a thicker or stronger material and an expensive one Shell, its practicality is stronger.

Description

technical field [0001] The invention relates to compressor improvement technology, in particular to a high-strength compressor shell structure with higher mechanical strength. Background technique [0002] At present, as a new environmentally friendly refrigerant, R410A refrigerant is gradually replacing R22 refrigerant with its advantages of not destroying the ozone layer, extremely low toxicity, and high cooling (warming) efficiency. Since the working pressure of the R410A refrigerant is about 1.6 times that of the R22 refrigerant, the mechanical strength requirements of the compressor shell are also higher than that of the R22 refrigerant to meet the industry standard requirements of this type of compressor. The mechanical strength requirement of the compressor casing using R22 refrigerant is ≥166kg / cm 2 , while the mechanical strength of the compressor shell using R410A refrigerant is about 220kg / cm 2 , when a compressor using R22 refrigerant undergoes a mechanical str...
