Open impeller for hydrokinetic machines

摘要

The invention relates to an impeller for hydrokinetic machines and, in particular, centrifugal pumps, which is made up of individual impeller segments (7) which each comprise an impeller wall segment (8) and a blade (3) formed on the latter and are secured at least on the common hub (9). According to a preferred embodiment, the impeller wall (2) is inclined in such a way relative to the inlet region (E) in the axial direction that the front edges (6) of the blades (3) are rectilinear in the meridian cross-section and lie in a plane perpendicular to the axis of rotation. <IMAGE>
