Embodiment 2
[0057] Refer below Figure 4 , Figure 5a -b, Figure 6a -b describes the pump body fixing assembly of the rotary double-cylinder compressor provided by the second embodiment of the present invention.
[0058] Figure 4 It is a partial assembly schematic diagram of Embodiment 2 of the rotary twin-cylinder compressor assembly of the present invention;
[0059] Figure 5a -b is a schematic structural diagram of the specific intermediate partition of Embodiment 2 of the rotary twin-cylinder compressor assembly of the present invention, Figure 6a -b is a schematic diagram of the bracket structure of Embodiment 2 of the inventive rotary twin-cylinder compressor assembly.
[0060] Embodiment 2 is different from Embodiment 1 in terms of the structure of the bracket and the middle partition, but the connection method is the same, and the connection relationship between other components and various devices and components is the same, and will not be repeated here. Specifically, ...

The invention discloses a fixing assembly for a rotation type dual-cylinder compressor pump body, wherein the fixing assembling is arranged between the pump body and a compressor housing. The fixing assembly comprises: a center separation plate, which is used for separating an upper cylinder and a lower cylinder of the compressor and is arranged at the pump body; and a support, which is arranged between the compressor housing and the pump body. The support and the compressor housing are fixedly connected; and the center separation plate and the support are fixedly connected. In addition, the invention also discloses a rotation type dual-cylinder compressor containing the fixing assembly. The rotation type dual-cylinder compressor pump body is fixedly assembled at the rotation type dual-cylinder compressor reliably, so that a problem that the existing rotation type dual-cylinder compressor pump body fixing assembly has the technical defects can be solved.
Description
technical field [0001] The invention relates to the field of compressor equipment used in systems such as air conditioners, refrigerators, and cold storage, and in particular to a pump body fixing assembly of a rotary double-cylinder compressor, a fixing method and a compressor. Background technique [0002] Rotary twin-cylinder compressors are compressor equipment widely used in air conditioners, refrigerators, cold storage and other systems. In the prior art, there are mainly two ways to fix the pump body of the rotary double-cylinder compressor. One way is to fix the pump body by welding the cylinder, and the other way is to fix it by welding the upper flange. [0003] By analyzing the above two pump body fixing methods, we can find that they both have certain defects: the defect of the welding cylinder fixing method is that the welding heat causes thermal deformation of the sliding vane groove and thermal deformation of the cylinder, which affects the performance of the ...
