工作原理
? ?当叶轮旋转时,气体从进风口轴向进入叶轮,受到叶轮上叶片的推挤而使气体的能量升高,然后流入导叶。导叶将偏转气流变为轴向流动,同时将气体导入扩压管,进一步将气体动能转换为压力能,然后引入工作管路。
? ?轴流式风机叶片的工作方式与飞机的机翼类似。但是,后者是将升力向上作用于机翼上并支撑飞机的重量,而轴流式风机则固定位置并使空气移动。
? ?轴流式风机的横截面一般为翼剖面。叶片可以固定位置,也可以围绕其纵轴旋转。叶片与气流的角度或者叶片间距可以不可调或可调。改变叶片角度或间距是轴流式风机的主要优势之一。小叶片间距角度产生较低的流量,而增加间距则可产生较高的流量。
? ?先进的轴流式风机能够在风机运转时改变叶片间距(这与直升机旋翼颇为相似),从而相应地改变流量。这称为动叶可调(VP)轴流式风机。
使用
? ?轴流风机又叫局部通风机,是工矿企业常用的一种风机,但不同于一般的风机它的电机和风叶都在一个圆筒里,外形就是一个筒形,用于局部通风,安装方便,通风换气效果好,可以接风筒把风送到指定的区域。
