Title: Centrifugal type fluid machine
Inventor: NAGAOKA YOSHIHIRO
IPC: F04D29/66
Filed: 1993-12-17
Abstract: PURPOSE:To decrease the generation of noise by a method wherein pressure pulsation and an exciting force exerted on a diffuser or a volute is relaxed or offset. CONSTITUTION:A fluid machine comprises an impeller 3 rotated in a casing 1 around a rotary shaft 2; and diffuser 4 with a blade or a volute fixed to the casing 1. The diameter of the rear edge of the impeller 3 and the diameter of the front edge of the diffuser 4 or the diameter of the winding starting of the volute are changed in the direction of the central line of a rotary shaft. Inclination of the rear edge of the blade of the impeller 3 and the front edge of the blade of the diffuser 4 or the meridian plane of the winding starting of the volute are the same as each other. This constitution suppresses reduction of a head and efficiency or the generation of shaft thrust as much as possible and reduces the generation of noise and pressure pulsation of a centrifugal type fluid machine to an optimum.
