Compressor air suction structure

Abstract

The invention discloses a compressor air suction structure. The compressor air suction device comprises a compressor, a liquid storage device, a bend and a guide pipe. An air suction hole of the compressor and the liquid storage device are in communication on the basis of connection of the bend and the guide pipe or connection of the bend, the guide pipe and the air suction hole. The guide pipe is provided with a guide pipe peripheral end, and welding connection is achieved on the basis of the guide pipe peripheral end and the bend. During using, the temperature of a pipeline between the liquid storage device and the air suction hole of the compressor is lower than the temperature of an existing compressor air suction structure during welding, and it is guaranteed that during welding, the pipeline and components arranged on the pipeline are not influenced by the high temperature or thermal shocks; and through the additional arrangement of a heat isolation layer, the energy efficiency ratio of the compressor can be effectively increased, and good practicability is achieved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor suction structure. Background technique [0002] figure 1 A schematic diagram of an existing compressor suction structure is shown. In the current compressor suction structure in the industry, the elbow 201 has a curved section and a straight section, one end of the curved section is connected to the liquid reservoir 200, and the other end is connected to the straight pipe section 202; The fixed pipe 103, the suction hole 101 of the compression chamber 100 is matched with the connecting pipe 301; the straight pipe section 202 is stuck on the variable diameter step of the connecting pipe 301, and the fixed pipe 103 is set outside the connecting pipe 301; 202, the connecting pipe 301, and the fixing pipe 103 are welded and fixed to form a seal. [0003] Nowadays, the commonly used brazing methods mainly include flame brazing or induction brazing. These two methods are mor...

Problems solved by technology

[0008] In order to overcome the problem of the existing compressor suction structure, the present invention provides a compressor suction structure, by adding a conduit with an outer edge end of the conduit for welding, and based on the fact that the total heat of welding is low and the heat-affected range is relatively concentrated The unique welding method realizes the connection between the conduit and the elbow, which effectively solves the problems of excessive welding thermal shock, long welding time, and excessive heat-affected range of the existing compressor suction structure, and has good practicability
