通风机选型程序与比转数优化的研究及应用

Research and Application of Type Selection Program and Specific Revolution Optimization in Fans

提出了通风机选型程序与运用各型经济比转数进行优化的研究及实际应用。分别说明了按用户通风机性能工况参数需求,计算不同比转数值,分别基于机型特征要领和选型设计准则进行型式结构预选→性能机号初选→转速和电机型式机组复选→综合分析筛选→最后终选定型的原则,得出了使用此程序选型可达到既快又节能的结论。

In this paper,the type selection program in fans is pointed out,and the research ＆ practical application of optimization using any type economical specific revolution are introduced.According to the performance operations and parametric requirements in fans by users,different specific values are calculated.The selection sequence is that the type structure pre-selection,the performance machine number pre-selection,the speed and motor type units repeated selection,the comprehensive analysis selection and the type selection at last,which is based on characteristic essentials of fan＇s type and selection design rules.The conclusion is that program can rapidly complete type selection and has the feature of energy-saving.
