To evaluate the effect of impeller design on pump hemolysis, five impellers with different number of vanes or different vane angles were manufactured and tested in one pump for hemolysis comparison. The impellers are made to have the same dimension and same logarithmic spiral vane from which coincide with the stream surfaces in the pump, according to the analytical and three-dimensional design method developed by the authors. Consequently, an impeller with 6 vanes and 30 degrees vane angle has the lowest hemolysis index. This result agrees with the theoretical analyses of other investigators searching optimal number of vanes and vane angle to achieve the highest efficiency of the pump.
为评估叶轮设计对泵溶血的影响，制造了五个具有不同叶片数量或不同叶片角度的叶轮，并在一台泵中进行测试以比较溶血情况。根据作者开发的分析和三维设计方法，使叶轮具有相同尺寸和相同的对数螺旋叶片，该叶片与泵中的流面重合。因此，一个具有6个叶片和30度叶片角度的叶轮具有最低的溶血指数。这一结果与其他研究人员寻找最佳叶片数量和叶片角度以实现泵最高效率的理论分析结果一致。
