鑒于軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)(ji)(ji)有紊(wen)(wen)流(liu)區的(de)(de)(de)性(xing)能(neng)特(te)點，在選型和使(shi)用時(shi)，需要注意以下(xia)(xia)兩點：建議使(shi)用在空曠環(huan)境中(zhong),軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)輸入功率隨系統靜(jing)壓的(de)(de)(de)增(zeng)大(da)而增(zeng)大(da)，而在紊(wen)(wen)流(liu)區，輸入功率的(de)(de)(de)增(zeng)大(da)幅度(du)會(hui)更大(da)。因此，軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)(ji)(ji)一般(ban)多(duo)應用在有較(jiao)(jiao)大(da)空曠環(huan)境的(de)(de)(de)場合下(xia)(xia)，可以使(shi)其工(gong)(gong)作(zuo)在靜(jing)壓較(jiao)(jiao)低的(de)(de)(de)環(huan)境下(xia)(xia)，降低功耗，保(bao)證穩(wen)定(ding)性(xing)和壽命。定(ding)期清理風(feng)(feng)(feng)道,當(dang)軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)(ji)(ji)應用在較(jiao)(jiao)為封閉的(de)(de)(de)風(feng)(feng)(feng)道系統中(zhong)時(shi)，長(chang)期運行后風(feng)(feng)(feng)道中(zhong)的(de)(de)(de)積灰、垃圾逐漸(jian)變多(duo)，會(hui)使(shi)風(feng)(feng)(feng)道內的(de)(de)(de)靜(jing)壓逐漸(jian)增(zeng)加，使(shi)得風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)運行工(gong)(gong)況點逐漸(jian)左(zuo)移。這不僅會(hui)降低風(feng)(feng)(feng)機(ji)(ji)(ji)性(xing)能(neng)，更重(zhong)要的(de)(de)(de)是會(hui)增(zeng)加軸(zhou)流(liu)風(feng)(feng)(feng)機(ji)(ji)(ji)進入紊(wen)(wen)流(liu)區的(de)(de)(de)風(feng)(feng)(feng)險。因此必須要定(ding)期清理風(feng)(feng)(feng)道，保(bao)證風(feng)(feng)(feng)機(ji)(ji)(ji)工(gong)(gong)況點不產生(sheng)較(jiao)(jiao)大(da)偏移。

風管主要指中央空調系統的通風管道，它常常被忽視，但卻是空調系統的重要組成部分，渝中電動防火閥目前常見的風管主要有四種：1）鍍鋅薄鋼板風管；2)無機玻璃鋼風管；3)復合玻纖板風管；4)纖維織物風管。鍍鋅薄鋼板風管：早使用的風管，電動防火閥批發采(cai)用(yong)鍍(du)鋅薄鋼板制(zhi)作(zuo)，適(shi)合含(han)濕量小的(de)一般性氣體的(de)輸送，有易(yi)生銹，無(wu)(wu)(wu)(wu)保溫(wen)和消聲功(gong)能，制(zhi)作(zuo)安(an)裝(zhuang)(zhuang)周期(qi)長的(de)特點。無(wu)(wu)(wu)(wu)機(ji)玻璃鋼風管(guan)：較新的(de)風管(guan)類型，采(cai)用(yong)玻璃纖維增(zeng)強無(wu)(wu)(wu)(wu)機(ji)材料制(zhi)作(zuo)，遇(yu)火不燃(ran)、耐腐蝕、份量重(zhong)，硬度大但較脆，受自重(zhong)影響(xiang)易(yi)變形酥裂，無(wu)(wu)(wu)(wu)保溫(wen)和消聲性能，制(zhi)作(zuo)安(an)裝(zhuang)(zhuang)周期(qi)長。

在(zai)(zai)葉(xie)(xie)(xie)輪(lun)(lun)運轉初期及所有定(ding)(ding)期檢查(cha)(cha)的時候，只(zhi)要(yao)一(yi)有機會，都必(bi)須(xu)(xu)檢查(cha)(cha)葉(xie)(xie)(xie)輪(lun)(lun)是(shi)否出(chu)現(xian)(xian)裂紋、磨損、積塵等缺陷。只(zhi)要(yao)有可能，都必(bi)須(xu)(xu)使(shi)(shi)葉(xie)(xie)(xie)輪(lun)(lun)保持清潔狀(zhuang)態，并定(ding)(ding)期用鋼絲刷(shua)(shua)刷(shua)(shua)去上面的積塵和(he)銹皮等，因為隨著(zhu)運行(xing)時間的加長，這些灰塵由于不(bu)可能均勻地附著(zhu)在(zai)(zai)葉(xie)(xie)(xie)輪(lun)(lun)上，而造成葉(xie)(xie)(xie)輪(lun)(lun)平(ping)衡(heng)(heng)(heng)破(po)壞，以至(zhi)引起(qi)轉子振(zhen)動(dong)。葉(xie)(xie)(xie)輪(lun)(lun)只(zhi)要(yao)進(jin)(jin)行(xing)了修理，就需要(yao)對其再作動(dong)平(ping)衡(heng)(heng)(heng)。如有條件，可以使(shi)(shi)用便(bian)攜(xie)試動(dong)平(ping)衡(heng)(heng)(heng)儀在(zai)(zai)現(xian)(xian)場進(jin)(jin)行(xing)平(ping)衡(heng)(heng)(heng)。在(zai)(zai)作動(dong)平(ping)衡(heng)(heng)(heng)之前，必(bi)須(xu)(xu)檢查(cha)(cha)所有緊(jin)定(ding)(ding)螺栓是(shi)否上緊(jin)。因為葉(xie)(xie)(xie)輪(lun)(lun)已經(jing)在(zai)(zai)不(bu)平(ping)衡(heng)(heng)(heng)狀(zhuang)態下(xia)運行(xing)了一(yi)段時間，這些螺栓可能已經(jing)松動(dong)。
