Parametric Design System Development of Centrifugal Pump Impeller Based on SolidWorks

In order to realize the prototype-free three-dimensional modelling of the impeller and the parametric modelling of the front and rear cover plates, the design efficiency of the centrifugal pump impeller is improved. The system uses VB6.0, Microsoft Excel to achieve the secondary development of SolidWorks, and puts forward the basic principles and implementation methods for the development of the centrifugal pump impeller parametric design system based on SolidWorks, and derives the right-angle coordinate points of the blade flow line based on the wood-mode diagram, which greatly shortens the design and development cycle of the impeller.
