風(feng)(feng)(feng)(feng)機(ji)(ji)廣泛(fan)地應(ying)(ying)用(yong)(yong)(yong)(yong)于各個工業部門(men)，一般講，離心式(shi)(shi)風(feng)(feng)(feng)(feng)機(ji)(ji)適用(yong)(yong)(yong)(yong)于小流量、高(gao)壓(ya)力的(de)(de)(de)場所，而軸(zhou)流式(shi)(shi)風(feng)(feng)(feng)(feng)機(ji)(ji)則常(chang)用(yong)(yong)(yong)(yong)于大流量、低壓(ya)力的(de)(de)(de)情況(kuang)，應(ying)(ying)根據不同的(de)(de)(de)情況(kuang)選有不同的(de)(de)(de)風(feng)(feng)(feng)(feng)機(ji)(ji)分(fen)類。1鍋(guo)爐用(yong)(yong)(yong)(yong)風(feng)(feng)(feng)(feng)機(ji)(ji),鍋(guo)爐用(yong)(yong)(yong)(yong)風(feng)(feng)(feng)(feng)機(ji)(ji)根據鍋(guo)爐的(de)(de)(de)規格可(ke)選用(yong)(yong)(yong)(yong)離心式(shi)(shi)或(huo)軸(zhou)流式(shi)(shi)。又按它(ta)的(de)(de)(de)作用(yong)(yong)(yong)(yong)分(fen)為鍋(guo)爐風(feng)(feng)(feng)(feng)機(ji)(ji)—向(xiang)鍋(guo)爐內輸送(song)空氣(qi)；鍋(guo)爐引(yin)風(feng)(feng)(feng)(feng)機(ji)(ji)把鍋(guo)爐內的(de)(de)(de)煙(yan)氣(qi)抽走(zou)。2通風(feng)(feng)(feng)(feng)換(huan)氣(qi)用(yong)(yong)(yong)(yong)風(feng)(feng)(feng)(feng)機(ji)(ji),這類風(feng)(feng)(feng)(feng)機(ji)(ji)一般是供工廠(chang)及各種建筑(zhu)物通風(feng)(feng)(feng)(feng)換(huan)氣(qi)及采(cai)暖(nuan)通風(feng)(feng)(feng)(feng)用(yong)(yong)(yong)(yong)，要求壓(ya)力不高(gao)，但噪(zao)聲要求要低，可(ke)采(cai)用(yong)(yong)(yong)(yong)離心式(shi)(shi)或(huo)軸(zhou)流式(shi)(shi)風(feng)(feng)(feng)(feng)機(ji)(ji)。

鑒于軸(zhou)流(liu)風(feng)(feng)機有紊(wen)流(liu)區的(de)(de)(de)性(xing)(xing)能特點，在(zai)選型(xing)和使(shi)用時(shi)，需要注意以下兩(liang)點：建議使(shi)用在(zai)空(kong)曠環(huan)境(jing)中(zhong),軸(zhou)流(liu)風(feng)(feng)機的(de)(de)(de)輸入功率隨系統靜壓(ya)的(de)(de)(de)增大(da)而增大(da)，而在(zai)紊(wen)流(liu)區，輸入功率的(de)(de)(de)增大(da)幅度會(hui)(hui)(hui)更(geng)大(da)。因此(ci)，軸(zhou)流(liu)風(feng)(feng)機一般多應(ying)用在(zai)有較大(da)空(kong)曠環(huan)境(jing)的(de)(de)(de)場合(he)下，可以使(shi)其工(gong)(gong)作在(zai)靜壓(ya)較低(di)的(de)(de)(de)環(huan)境(jing)下，降低(di)功耗，保(bao)證穩定性(xing)(xing)和壽命(ming)。定期(qi)清(qing)理風(feng)(feng)道,當軸(zhou)流(liu)風(feng)(feng)機應(ying)用在(zai)較為封閉的(de)(de)(de)風(feng)(feng)道系統中(zhong)時(shi)，長期(qi)運行(xing)后風(feng)(feng)道中(zhong)的(de)(de)(de)積灰(hui)、垃圾逐漸變多，會(hui)(hui)(hui)使(shi)風(feng)(feng)道內的(de)(de)(de)靜壓(ya)逐漸增加，使(shi)得(de)風(feng)(feng)機的(de)(de)(de)運行(xing)工(gong)(gong)況點逐漸左移(yi)。這不(bu)僅會(hui)(hui)(hui)降低(di)風(feng)(feng)機性(xing)(xing)能，更(geng)重(zhong)要的(de)(de)(de)是(shi)會(hui)(hui)(hui)增加軸(zhou)流(liu)風(feng)(feng)機進入紊(wen)流(liu)區的(de)(de)(de)風(feng)(feng)險。因此(ci)必須要定期(qi)清(qing)理風(feng)(feng)道，保(bao)證風(feng)(feng)機工(gong)(gong)況點不(bu)產生較大(da)偏移(yi)。
