Parameterized Design of Centrifugal Fans Impeller

摘要：

On the base of the study on the selecting method and regularity of a large number of existing high performance centrifugal fans main parameters, the corresponding relations between specific speed and specific diameter, as well as between specific speed and exit width of blade, were found.Base on the statistical datas, a new method, which determines the main geometric parameters of centrifugal fans impeller, was proposed.By means of the parametric design method, the paper develops the special CAD system of centrifugal fans.This system based on AutoCAD, mainly includes module of impellers aerodynamic design and module of impellers parametric drawing, is developed by VBA.This system can achieve computer-aided design of different types of impellers, completely realize human-machine interactive function, meanwhile the efficiency of design and quality of impeller products are enhanced.
