Abstract
The invention discloses a welding structure of a rotary type compressor pump body. The welding structure is utilized for cylinder welding or flange welding. The external circumference of a cylinder or a flange is provided with at least two welding apertures, and two sides of each one of the at least two welding apertures are provided with concave portions. The concave portions change a pathway of welding heat transmission and a bearing form of a fixed part, enable a cylinder or a flange to cooperate with a housing body by the minimum area, and reduce extrusion effects on a cylinder body, wherein the extrusion effects are caused by housing body deformation produced by welding, thus welded fixed part stiffness is increased; welding deformation is improved; and compressor performances are improved.
