Centrifugal fluid machinery and its control device

Abstract

PURPOSE: To improve operating efficiency by realizing a collisionless angle of incidence as much as possible in the overall operating territory in a centrifugal fluid machine provided with an impeller. CONSTITUTION: Each of blades 4 is constituted of a fixed blade part 41 formed integrally with a hub 3 and a movable blade part 42 connected to an edge part of the fixed blade part 41 inclining towards a fluid inflow part 11 free to tilt in the direction of its board thickness through a connecting shaft 43 and formed separately from the hub 3. Additionally, it is possible to change and adjust an angle of incidence (i) of fluid against the impeller 2. COPYRIGHT: (C)1992,JPO&Japio
