离心通风机的优化组合设计方法实例

Methods And Examples of Optimized Combination Design For Centrifugal Fan

用 5- 56风机及 6- 4 9风机的实例阐述了采用优先数系优化组合设计离心风机的方法 ,并说明了采用该方法设计的风机在系列化生产时可大量减少工装胎具 ,方便生产管理。阐明了用优先数系方法改变离心风机性能的可靠性。

Method of centrifugal fan designed by priority number system & optimized combination is set forth by using example of type 5-56 & 6-49 fans.The fan designed by this method can greatly minimize die block in serilization production is described,and easy to production management,Reliability of performance of centrifugal fan changed by the method of priority number system is explained.
