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。由于配件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，值得信賴的配件從排氣口排出(chu)。因(yin)氣體在葉(xie)輪(lun)(lun)內(nei)的(de)流動主要(yao)是在徑向平面內(nei)，故又稱(cheng)徑流風(feng)(feng)機(ji)(ji)。離心風(feng)(feng)機(ji)(ji)主要(yao)由葉(xie)輪(lun)(lun)和機(ji)(ji)殼(ke)組(zu)成，小(xiao)型(xing)風(feng)(feng)機(ji)(ji)的(de)葉(xie)輪(lun)(lun)直接裝在電(dian)動機(ji)(ji)上中、大(da)型(xing)風(feng)(feng)機(ji)(ji)通過聯軸器或皮(pi)帶輪(lun)(lun)與(yu)電(dian)動機(ji)(ji)聯接。離心風(feng)(feng)機(ji)(ji)一般為單側進(jin)氣，用(yong)單級葉(xie)輪(lun)(lun)；流量(liang)大(da)的(de)可(ke)雙(shuang)側進(jin)氣，用(yong)兩個(ge)背靠背的(de)葉(xie)輪(lun)(lun)，又稱(cheng)為雙(shuang)吸式離心風(feng)(feng)機(ji)(ji)。

1) 送風(feng)(feng)(feng)(feng)，包(bao)括通氣(qi)(qi)，如送鮮風(feng)(feng)(feng)(feng)和(he)排氣(qi)(qi)，這(zhe)個范圍(wei)很廣(guang)，如工(gong)廠車間(jian)，生(sheng)(sheng)(sheng)產場地空(kong)(kong)氣(qi)(qi)，由于(yu)有(you)(you)害(hai)氣(qi)(qi)體產生(sheng)(sheng)(sheng)需(xu)(xu)要(yao)(yao)排出室外，又需(xu)(xu)要(yao)(yao)把室外空(kong)(kong)氣(qi)(qi)輸(shu)送至室內。這(zhe)時(shi)就要(yao)(yao)使(shi)(shi)用(yong)(yong)(yong)流量(liang)大(da)而壓力小(xiao)的(de)(de)(de)空(kong)(kong)氣(qi)(qi)輸(shu)送管(guan)(guan)(guan)道，螺(luo)旋風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)就適用(yong)(yong)(yong)，一(yi)般情(qing)況下使(shi)(shi)用(yong)(yong)(yong)鍍鋅鐵(tie)管(guan)(guan)(guan)，有(you)(you)腐蝕性(xing)及特(te)別潮濕場所使(shi)(shi)用(yong)(yong)(yong)不銹鋼管(guan)(guan)(guan)。2) 送冷(leng)風(feng)(feng)(feng)(feng)。常見的(de)(de)(de)是中央空(kong)(kong)調的(de)(de)(de)管(guan)(guan)(guan)道，這(zhe)種管(guan)(guan)(guan)道需(xu)(xu)要(yao)(yao)加保溫(wen)(wen)材料(liao)。螺(luo)旋風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)可內貼保溫(wen)(wen)材料(liao)，外表(biao)看來美觀。3) 排油煙。飯店、酒樓、賓(bin)館的(de)(de)(de)廚(chu)房均有(you)(you)大(da)量(liang)油煙產生(sheng)(sheng)(sheng)，需(xu)(xu)要(yao)(yao)排出，使(shi)(shi)用(yong)(yong)(yong)圓(yuan)形(xing)的(de)(de)(de)風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)就是油煙囪(cong)。在這(zhe)里，螺(luo)旋風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)該叫(jiao)做油煙管(guan)(guan)(guan)。4) 除塵。有(you)(you)些(xie)工(gong)廠生(sheng)(sheng)(sheng)產車間(jian)很多塵埃，需(xu)(xu)要(yao)(yao)專門的(de)(de)(de)除塵裝置，其中量(liang)較大(da)的(de)(de)(de)管(guan)(guan)(guan)道，可使(shi)(shi)用(yong)(yong)(yong)螺(luo)旋風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)。5) 散裝物料(liao)輸(shu)送。有(you)(you)些(xie)工(gong)廠的(de)(de)(de)生(sheng)(sheng)(sheng)產過(guo)程中，需(xu)(xu)要(yao)(yao)輸(shu)送松散的(de)(de)(de)顆粒，特(te)別是比(bi)重不大(da)的(de)(de)(de)如發泡(pao)塑料(liao)粒之類的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)螺(luo)旋風(feng)(feng)(feng)(feng)管(guan)(guan)(guan)造價低、效果好。
