風機分類可以按氣體流動的方向，分為離心式、軸流式、斜流式和橫流式等類型。這種風機分類的機器有：離心風機工作時，動力機(主要是電動機)驅動葉輪在蝸形機殼內旋轉，空氣經吸氣口從葉輪中心處吸入。由于天園地方管葉片對氣體的動力作用，氣體壓力和速度得以提高，并在離心力作用下沿著葉道甩向機殼，推薦天園地方管從排氣(qi)(qi)口排出(chu)。因氣(qi)(qi)體在葉輪(lun)(lun)(lun)內的(de)流動主要是在徑向(xiang)平(ping)面內，故又稱徑流風(feng)(feng)機(ji)(ji)(ji)。離(li)心(xin)風(feng)(feng)機(ji)(ji)(ji)主要由葉輪(lun)(lun)(lun)和(he)機(ji)(ji)(ji)殼組成(cheng)，小型風(feng)(feng)機(ji)(ji)(ji)的(de)葉輪(lun)(lun)(lun)直接裝在電動機(ji)(ji)(ji)上中、大(da)型風(feng)(feng)機(ji)(ji)(ji)通過聯軸器(qi)或皮(pi)帶輪(lun)(lun)(lun)與(yu)電動機(ji)(ji)(ji)聯接。離(li)心(xin)風(feng)(feng)機(ji)(ji)(ji)一般為單側進氣(qi)(qi)，用單級葉輪(lun)(lun)(lun)；流量大(da)的(de)可(ke)雙側進氣(qi)(qi)，用兩(liang)個背靠背的(de)葉輪(lun)(lun)(lun)，又稱為雙吸式離(li)心(xin)風(feng)(feng)機(ji)(ji)(ji)。
