| 摘 要： | 归纳了轴流泵的叶片设计理论,总结了叶片几何参数的选择原则,指出了叶片设计中存在的问题,给出了提升现有轴流泵叶片设计理论的策略.研究表明,现有轴流泵的叶片设计理论单一,缺少更多有效控制叶片形状的变量和手段.采用三维流动理论,改变叶片造型方法,控制水力损失和引入CFD方法是提升现有轴流泵叶片设计的主要策略.

| Abstract: | The vane design theories of axial-flow pumps and principles of vane geometry selection are reviewed,and the uncertainty pump design is also pointed out.The strategy of improvement of the existing design theories is proposed.The investigation results show that the existing vane design theory is rather too simple and there are less variables and methods for effectively controlling the vane configuration and geometry.The main strategy should include in itself the use of three-dimensional flow theory,improvement of vanes stacking skill,control of hydraulic losses,and use of CFD in vane design procedure. |
