Centrifugal compressor and centrifugal unit having the same
The invention discloses a centrifugal compressor. The centrifugal compressor includes multiple stages of compression units which are communicated in sequence. Each stage of compression unit includes a diffusion cavity (1) and a diffusion adjustment device, wherein the diffusion adjustment device includes a movable member (21) configured to change a radial flow area of the diffusion cavity (1) provided in correspondence thereto, the movable member (21) being movably provided in an axial direction of the centrifugal compressor. The invention also discloses a centrifugal unit having the centrifugal compressor. The movable member of each stage of compression unit of the centrifugal compressor changes the radial flow area of the diffusion cavity of this stage of compression unit, thereby effectively reducing the possibility of surging.
