凯泉叶轮的设计注重高效、低振动、抗冲刷和长寿命。其叶片布置均匀，具有良好的动静平衡性能，运转平稳，动平衡精度不低于G6.3级 。部分叶轮采用优化设计，如最佳叶片包角为126°，叶片出口角度为24°，以提升扬程和效率。Experimental Analysis Via numerical simulation in Part 6, Scheme 5 was determined to be the best one. The corresponding impeller was machined. Then, the performance experiments were done in the closed performance experiment rig of Shanghai Kaiquan Pump Group to verify that head and efficiency of the centrifugal pump with the Impeller 5 showing obvious improvement. Experiment Setup The impeller machining process was displayed in Figure 19. At the outlet of the impeller, the allowance was 5 mm, as shown in region A. Allowance of the impeller front shroud and back shroud was 3 mm, as exhibited in region B. At the inlet of the impeller, the allowance was 3 mm too, as displayed in region C. Allowance of the hub was 3 mm, as shown in region D.
