摘　　要：基于离心泵优秀水力模型,对其流道中线的离散点,用贝塞尔曲线进行拟合,求出插值三次贝赛尔曲线,进而推导出前后盖板流线的方程。通过SolidWorks二次开发技术,实现了轴面流道的参数化设计,具有一定的工程应用价值。Through repeated adjustment and check to meet requirement according to sectional area of through-flow and internal tangent circle method,the design of meridional flow channel of centrifugal pump is dependent on experiences,which is of blindness and complexity.On the basis of excellent hydraulic model,discrete points on middle streamline of meridional flow channel are fitted using Bezier curve.Then,expressions of cubic interpolation Bezier curve and equations of impeller shroud are deduced.Parametrical design of meridioanl flow channel is realized by means of SolidWorks development technology.
