Abstract
PURPOSE: To reduce vibrations and noises caused by cavitation by providing the plural number of guide vanes on the circumference of a flow passage upstream an inducer, which give preturning in the direction of inducer rotation to flows introduced into the inducer in order to reduce relative velocities.
CONSTITUTION: The plural number of guide vanes 5 are provided on the circumference of a flow passage with a high relative velocity formed by a casing 4 located upstreams the inducer 2 in order to give preturnings in the direction of inducer rotation to flows introduced into the inducer 2. The flowing state in the circumference of the entrance of the inducer 2 is shown by broken lines for a case without guide vanes 5 and by solid lines for a case with guide vanes 5 as illustrated. An actual velocity C1' is inclined as locking like C1 in the direction of inducer rotation due to existence of guide vanes 5, and a relative velocity W1' is reduced to W1. Thereby, vibrations and noises caused by cavitation in this dred can be reduced. "u1 shows the circumferential velocity of the inducer 2.
