Centrifugal wheel with fish tail fin blades

The utility model discloses a centrifugal wheel with fish tail fin blades. The centrifugal wheel comprises a centrifugal wheel shell, a centrifugal rotating disc rotationally arranged in the centrifugal shell and rotating blades arranged on the centrifugal rotating disc. According to the centrifugal wheel with the fish tail fin blades in the technical scheme, different fish tail fins are arranged at the end parts of the long blades and the short blades, so that fluid forms a similar liquid flow arc wall in high-speed rotation, the disordered flowing states such as reverse swirling flow of the fluid are hindered, and the flow speed of the fluid is increased; the phenomena of secondary flow, vortex, backflow and the like are effectively prevented from being formed in the high-speed centrifugal pump, so that the volume loss and the hydraulic loss of the high-speed centrifugal pump are greatly reduced, and the steady-state performance in the high-speed centrifugal pump is improved. 本实用新型公开了一种具有鱼尾鳍叶片的离心轮，包括离心轮壳体、可
