摘要
空气管道出口处负压现象的发现 ,打破了传统的空气管道终端压力分布理论 ,改变了人们长期形成的风机出口管道终端不会出现负压的观念。在阐明风机全压基本概念及其用途的基础上 ,着重从条件和原因方面 ,分析管道出口处出现负压的机理 。
The traditional pressure distribution theory in air pipeline has been smashed by discovery of vacuum phenomena in the outlet of air pipeline. The view, that there is no vacuum in the outlet of fan, has been changed. On the basis of description for basic concept of fan full pressure and its application, the principle of vacuum phenomena in the respect of forming condition and cause has been analyzed and some important conclusions has been obtained.
