| Abstract: | 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 desig... |
