ABSTRACT:
A multistage fluid machine includes a casing, a rotary shaft, and a plurality of impellers mounted on the rotary shaft in a multistage arrangement. The impellers are fixed to the rotary shaft in such a manner that, when the impellers are projected on a plane normal to the rotary shaft, all the blades of the impellers are shifted out of phase with respect to each other in the circumferential direction on that plane in order to reduce the vibrations of the casing.
