Abstract
512,098. Centrifugal pumps. MASCHINENFABRIK AUGSBURG-NURNBURG AKT.- GES. Oct. 17, 1938, No. 30037. Convention date, Oct. 19, 1937. Drawings to Specification. [Class 110 (i)] In a centrifugal pump with an impeller having radial vanes projecting from a central boss and each lying in a plane at right angles to the direction of rotation, the shape of each vane is such that the initial and final values of passage depth plotted above the centre-line of flow encloses an angle with the horizontal of 19 degrees or more. When the initial depth of the passage is constant for a certain distance from the inlet, the initial value is taken at the commencement of the contraction and the angle is then 22 degrees or more. The outlet area of passage is less than 65 times the inlet area. Each vane may have the end of its leading edge arched in the direction of flow, the back of the vane remaining rectilinear. Specification 279,426, [Class 110 (i)], is referred to.
