摘要
为克服低比转数离心泵叶轮常用圆柱形叶片的表面脱流 ,提高叶轮水力效率 ,设计了一种渐开线圆柱形叶片 ,并以数学分析方法证明了渐开线两项重要几何特性 。
In order to prevent flow from separating along cylindrical blade surface of low specific speed impellers and improve hydraulic efficiency of the blades, the author of this paper designed a new type of cylindrical blade with involute contour and showed two important characteristics of involute mathematically. These features mean the new curve to have access to excellent hydraulic qualities when employed in cylindrical blades.
