TH104696B - Impeller plates for centrifugal pumps and pumps containing such impeller plates - Google Patents

Abstract

The impeller plate of the centrifugal pump 11 consists of an impeller body where the inner cavity 35 is formed, and a single centrifugal impeller 37 is provided in the impeller body. To have a leading edge at the exit and an edge at a predetermined point of the surface along the outer circumference Of the impeller plate body The centrifugal impeller 37 is designed so that the area of the external channel 36, where will be determined by the centrifugal impeller 37, at an angle of 270 degrees in the circumferential direction. From the along edge of the centrifugal impeller 37 to the total area of the rotor body surrounded by the surface The outer circumference of the rotor body is less than 0.3.
