SINGLE-ENTRY RADIAL PUMP

摘要

Single-entry radial pump with a low specific speed with a closed impeller with active blade surfaces or central stream lines of the flow passage between two consecutive blades similar to the camber line of the blades achieved by conforming representation or by means of the point method is characterized by the fact that the impeller has discs (1, 2) and blades (3) shaped in such a way that the cross-sections (5) of its diffuser passages keep the shape of their cross-sections similar to each other, perpendicular to the central stream line of the passage between the blades over its entire length.
