IMPELLER OF CENTRIFUGAL HYDRAULIC MACHINE

摘要

An impeller of centrifugal hydraulic machine has upper and lower rims and blades fixed between those, surfaces of those are arranged according to given relation of geometric parameters. Such implementation makes it possible to obtain impeller of centrifugal hydraulic machine with low level of pulsations in flow-through section, with large zone of high efficiency, with high level of maximal efficiency at keeping high operation velocity of the impeller.
