Compressor with compression pump body support member

Abstract

The invention relates to a compressor with a compression pump body support member. The compressor comprises a closed shell which is internally provided with a motor assembly and a compression pump body, and a gas-liquid separator communicated with the compression pump body through an air inlet elbow, wherein the compression pump body comprises an upper flange, an air cylinder and a lower flange which are axially arranged along a rotor shaft of a compressor; and the compression pump body support member is arranged between the lower flange and the lower cover of the closed shell and is used for supporting the compression pump body, the upper end of the compression pump body support member is contacted with the lower flange, and the lower end of the compression pump body support member is arranged on a lower cover. The compressor provided by the invention adopts the compression pump body support member to support the compression pump, and the length accuracy of the support member is higher than the positioning accuracy of a stamping hole in a copper suction pipe and a shell; the original unilateral locating support with a suction pipe is changed into symmetrical positioning fixation, the problem of inclination in welding is overcome, and the coaxiality of a stator and a rotor are effectively improved; and the altitude difference of the stator and the rotor is guaranteed, and the property and stability of a compressor are improved.

Background technique [0002] Such as figure 1 As shown, it is a structural schematic diagram of a compressor in the prior art, which includes a closed casing 100 with a motor assembly and a compression pump body inside, and communicates with the compression pump body in the compressor through an intake elbow 101 The gas-liquid separator 102 is provided with an exhaust pipe 103 at the upper end of the closed casing 100 . The motor assembly of the compressor includes a stator 104 and a rotor 105 rotatably disposed in the stator 104 , and the compressor shaft 106 is driven to rotate by the rotor 105 . The compression pump body includes an upper flange 107, a cylinder 108 and a lower flange 109 installed in sequence along the axial direction of the compresso...

AI Technical Summary

Problems solved by technology

[0003] When the existing compressor is spot welded, the suction pipe (i.e. the intake elbow 101) of the compression pump body is inserted into the compression pump body for positioning. Since the suction port of the closed casing 100 is stamped, The trachea pipe 101 is slightly smaller than the connecting pipe at the suction port. In addition, the suction pipe is mostly made of soft and easily deformed copper pipes, which is prone to inaccurate positioning, resulting in the height difference between the stator and the rotor cannot be well guaranteed, and , before the spot welding of the compressor is completed, it is easy to make the pump body assembly and the rotor tilt to the other side of the rotor contact gap together by only relying on the suction pipe on one side of the compressor, thereby affecting the same position of the stator and rotor of the compressor. In addition, the spot welding strength of existing compressors is high and generates a lot of heat, which will lead to large deformation of the upper flange (or cylinder), and will also cause wear and stuck of the pump body parts. The performance and stability of the machine are very unfavorable
