【摘要】 在离心泵的水力设计中,传统的叶轮轴面流线的分点方法,由于重复取值,反复对比,累积误差大,并造成轴面流线分点的速度低、精度差。为了提高叶轮水力设计过程中轴面流线分点的效率及准确性,文章通过几何分析的数学方法,对常见的轴面流线分点过程进行数学描述,并最终形成可供微机编程的计算公式。更多还原

【Abstract】 When the traditional impeller axial streamline segmenting method is implemented in the hydraulic design of centrifugal impeller, it requires repeating choosing the values and comparing their suitability, resulting in the accumulated errors. Therefore, it is slow and with low precision. In order to obtain higher efficiency and accuracy, this article brings out a mathematical method by geometric analyzing and the algebraic description for the progress of segmenting axial streamline. It finally gives the formulas that can be used in computer programming.更多还原
