Example Embodiment
[0039] figure 1 with figure 2 The shape and geometry of the impeller of this embodiment are jointly determined. This is a closed structure compound variable curvature low specific speed centrifugal pump impeller. The front cover (4) of the impeller and the rear cover (6) of the impeller have straight radial dimensions and structure, and the axial section through the flow passage is relatively straight. Wide, allowing solid particles of a certain size to pass through. The splitter blades (8) and the forward curved blades (9) are distributed on the outer edge of the impeller, and both adopt straight blade type, in which the splitter blades (8) are evenly distributed between the backward curved blades (3), and their blade inclination angles are respectively α 1 And α 2 . The present invention uses the following relations to determine the outer diameter of the impeller (1) D, the inlet diameter of the impeller (2) D j , The width of the impeller outlet (5)b, the inner diameter of...
