摘要
在对中小型离心式主要通风机内部流场分析的基础上，提出了在主要通风机入口断面布置全压管、静压感压器直接测量主要通风机气动性能的方法。从测量误差分析及现场实践证明，该方法技术先进，测量数据精确。
Abstract On the basis of analysis of inner flowing field medium and small type centrigugal main fans a direct measuring method with total pressure tube and static pressure sensor located at the cross section of fan inlet is proposed for the dynamic behavior of main fans.It is demonstrated that the method is advance in technology and the measured data are precise by both error analysis of measurement and field practice.
