"Un ventilateur est une machine utilisée pour comprimer et transporter des气体气体。D'un point de vue énergétique, il convert是把原动机的机械能量转变为气体能量的一种机械。http://p3.pstatp.com/large/66ba0001918ba8ad868a一、分类及用途根据作用原理分类:透平式风机--通过旋转叶片压缩输送气体的风机。容积式风机—用改变气体容积的方法压缩及输送气体机械。http://p9.pstatp.com/large/66b8a3b2b8983ba分类分类按气流运动方向分类:离心式风机—气流轴向驶入风机叶轮后,在在离心力作用下下被压缩;主要沿径向流动。轴流式风机—气流轴向驶入旋转叶片通道;由于叶片与气体相互作用,气体被压缩后近在圆柱型表面上沿轴线方向流动。混流式风机—气体与主轴成某一角度的方向进入旋转叶道;近似沿锥面流动。横流式风机—气体横贯旋转叶道;而受到叶片作用升压。按生产压力的高低分类(以绝对压力计算)通风机—排气压力低于112720Pa;鼓风机—排气压力在

2.2风机流量0~1000m海拨高度时可不修正;1000~1500M海拨高度时加2%的流量; 1500~2500M海拨高度时加3%的流量;2500M以上海拨高度时加5%的流量。 请问这个内容是哪里出现的呢?麻烦给分享一下,谢谢!
