Abstract

PURPOSE: To suppress irreguler vibration noises in a centrifugal compressor and to improve its performance by displacing an intermediate vane from the midpoint of each two main vanes so as to make the front side effective passage area equal to that of the rear side.
CONSTITUTION: An intermediate vane 7A is provided at a point closer to a main vane 3B by offsetting it to the reverse side of the rotating direction. By this, the flow rate distribution at the front side of the intermediate vane 7A becomes equal to that at the rear side thereof, the load of the negative pressure side 9 of a main vane 3A is reduced, and the balance for main vanes 3A, 3B becomes good. Accordingly, the irreguler vibration noises can be suppressed, and the performance of a compressor is improved as a whole.
