Abstract

The compressor includes casing, motor and compression mechanism inside the casing. The compression mechanism includes cylinder, the first bearing plate, the second bearing plate, cylindrical piston and separating plate. The first bearing plate and the second bearing plate are fixed separately on two sides of the cylinder to support the rotating shaft and seal the cylinder, and the outer cylindrical surface of the second bearing plate is fixed onto the casing via a three-point welding structure. The present invention has welding structure on the second bearing plate and no welding in the cylinder body, and this can prevent deformation of the cylinder caused by welding heat and prevent thus caused refrigerant leakage, vibration and noise and raise the efficiency of the compressor.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to a rotary compressor capable of preventing cylinder deformation. Background technique [0002] Usually, an important reason that affects the performance of rotary compressors is: the deformation of the compressor components during the installation or operation of the compressor, especially the deformation of the compressor cylinder will cause air leakage and excessive wear of the sliding parts. [0003] Therefore, in order to improve the working efficiency of the compressor, reduce vibration, and reduce noise, it is necessary to prevent the deformation of the compressor components, especially the cylinder, as much as possible when installing and operating the compressor. However, the structure of the existing rotary compressor is difficult to effectively reduce the deformation of the compressor cylinder. [0004] like figure 1 , figure 2 As shown, the structure of the existing rotary com...
