风机按使用材质分类可以分好几种,如铁壳风机(普通风机)、玻璃钢风机、塑料风机、铝风机、不锈钢风机等等
风机分类可以按气体流动的方向,分为离心式、轴流式、斜流式(混流式)和横流式等类型。
(1)离心风机。气流轴向进入风机的叶轮后主要沿径向流动。这类风机根据离心作用的 原理制成,产品包括离心通风机、离心鼓风机和离心压缩机。
(2)轴流风机。气流轴向进入风机的叶轮,ysdzxcvb201605211近似地在圆柱形表面上沿轴线方向流动。这类风机包括轴流通风机、轴流鼓风机和轴流压缩机。
(3)回转风机。利用转子旋转改变气室容积来进行工作。常见的品种有罗茨鼓风机、回转压缩机。
风机根据气流进入叶轮后的流动方向分为:轴流式风机、离心式风机和斜流(混流)式风机。
风机按用途分为压入式局部风机(以下简称压入式风机)和隔爆电动机置于流道外或在流道内,隔爆电动机置于防爆密封腔的抽出式局部风机(以下简称抽出式风机)。
风机按照加压的形式也可以分单级、双级或者多级加压风机。如4-72是单级加压,高端风机则是多级加压风机。
风机按照用途划分可以分为:轴流风机、混流风机、屋顶风机、空调风机等。
风机按压力可分为低压风机、中压风机、高压风机。
按出口压力(升压)分为:通风机(≤1.5万Pa)、鼓风机(1.5~35万Pa)、压缩机(≥35万Pa)。
风机性能参数
风机的性能参数主要有流量、压力、功率、效率和转速。另外,噪声和振动的大小也是主要的风机设计指标。流量也称风量,以单位时间内流经风机的气体体积表示;压力也称风压,是指气体在风机内压力升高值,有静压、动压和全压之分;功率是指风机的输入功率,即轴功率。风机有效功率与轴功率之比称为效率。风机全压效率可达90%。
