Centrifugal compressor and centrifugal water chilling unit

摘要

A housing (10) including a mounting cavity (11) having a threaded portion (12) on the side wall, and an adjustment provided in the mounting cavity (11) and a screw that fits the threaded portion (12). A member (20), a drive member (30) mounted in the mounting cavity (11) and driving the adjustment member (20) to move forward and backward along the screw portion (12); And a tunable diffuser (40) fixedly connected to the member (20). A centrifugal water chilling unit has the centrifugal compressor. According to the centrifugal compressor and the centrifugal water chilling unit, the tilting tendency of the tunable diffuser and the problem of failure stop can be solved, and the reliability of the centrifugal compressor is greatly improved.
