单叶片开式叶轮的水力设计

Hydraulic Design of the Single-vane Opened Impeller

系统介绍了单叶片开式叶轮污水泵的水力设计方法,在多种规格泵的试验统计数据基础上,推出了确定叶轮主要尺寸的计算公式,对单叶片的形状和最佳流线的绘型方法进行了详细的阐述,并提出了改善泵性能的一些建议。

The hydraulic design method of the single-vane opened impeller is wholly introduced. And basing on the test statistical data of varies specs of pumps, the calculate formulation to ascertain the impeller main size is deduced. The shape of the single-vane and the drawing method of the optimal streamline are expatiated particularly, and many ideas to improve the pump performance are advanced here.
