Abstract

PURPOSE: To reduce a hydraulic machine such as pump impellor in size and weight and keep its efficiency at a high value with the titled method applied for making a casing, a stay vane and a speed ring have specified relations with each other.
CONSTITUTION: A casing is made small in size with the center of gravity 10 of the casing drum at the inlet portion of a spiral casing set on the rotary shaft side of a hydraulic machine. This setting is made as follows: the flow at the vicinity of the casing of the impellors and pump impellors having varied specific speeds is set within such a range as to satisfy the formula I of correlation: wherein Dc is the equivalent diameter of the section at the inlet of the casing, a the distance between the center of gravity of the casing section and the outermost circumference of a vane, b that between the gravity center and the center of an impellor shaft, and B is the minimum height of the vane.
