鑒(jian)于軸流(liu)(liu)風(feng)(feng)機(ji)(ji)有(you)紊流(liu)(liu)區(qu)的(de)(de)性(xing)能(neng)特點(dian)，在(zai)(zai)選型和(he)使(shi)(shi)用(yong)時(shi)，需要注意以下兩點(dian)：建(jian)議使(shi)(shi)用(yong)在(zai)(zai)空(kong)(kong)曠(kuang)環境(jing)中(zhong)(zhong),軸流(liu)(liu)風(feng)(feng)機(ji)(ji)的(de)(de)輸入功(gong)(gong)率隨系統(tong)靜壓(ya)的(de)(de)增(zeng)大而(er)增(zeng)大，而(er)在(zai)(zai)紊流(liu)(liu)區(qu)，輸入功(gong)(gong)率的(de)(de)增(zeng)大幅(fu)度會更大。因此，軸流(liu)(liu)風(feng)(feng)機(ji)(ji)一般多應用(yong)在(zai)(zai)有(you)較大空(kong)(kong)曠(kuang)環境(jing)的(de)(de)場合下，可以使(shi)(shi)其工作在(zai)(zai)靜壓(ya)較低的(de)(de)環境(jing)下，降(jiang)低功(gong)(gong)耗(hao)，保證(zheng)穩(wen)定性(xing)和(he)壽命。定期(qi)清(qing)理(li)風(feng)(feng)道(dao),當軸流(liu)(liu)風(feng)(feng)機(ji)(ji)應用(yong)在(zai)(zai)較為(wei)封閉的(de)(de)風(feng)(feng)道(dao)系統(tong)中(zhong)(zhong)時(shi)，長期(qi)運行(xing)(xing)后風(feng)(feng)道(dao)中(zhong)(zhong)的(de)(de)積灰、垃圾逐漸變多，會使(shi)(shi)風(feng)(feng)道(dao)內的(de)(de)靜壓(ya)逐漸增(zeng)加，使(shi)(shi)得風(feng)(feng)機(ji)(ji)的(de)(de)運行(xing)(xing)工況(kuang)點(dian)逐漸左移(yi)。這不(bu)僅會降(jiang)低風(feng)(feng)機(ji)(ji)性(xing)能(neng)，更重要的(de)(de)是會增(zeng)加軸流(liu)(liu)風(feng)(feng)機(ji)(ji)進入紊流(liu)(liu)區(qu)的(de)(de)風(feng)(feng)險。因此必須要定期(qi)清(qing)理(li)風(feng)(feng)道(dao)，保證(zheng)風(feng)(feng)機(ji)(ji)工況(kuang)點(dian)不(bu)產(chan)生較大偏移(yi)。

1、 薄鋼板矩形風管的剛度不夠,表現形式：風管的大邊上下有不同程度的下沉，兩側面小邊稍向外凸出，有明顯的變形。貴州鍍鋅通風管對產生的原因分析：① 制作風管的鋼板厚度不符合施工及驗收規范的要求；② 咬口的形式選擇不當；③ 沒有按照《施工及驗收規范》要求，對于邊長≥630 mm或保溫風管≥800 mm，其管長在1 200mm以上，均應采取加固措施。2 、薄鋼板矩形風管扭曲、翹角,表現形式：風管表面不平；對角線不相等；相鄰表面互不垂直；兩相對表面不平行及兩管端平面不平行等。鍍鋅通風管產生的(de)原因分析：① 矩形(xing)板(ban)料(liao)下(xia)料(liao)后，未對四個(ge)角進行嚴(yan)格的(de)角方測(ce)量(liang)；② 風(feng)管的(de)大邊(bian)(bian)或小邊(bian)(bian)的(de)兩個(ge)相對面的(de)板(ban)料(liao)長度(du)和寬度(du)不(bu)相等；③ 風(feng)管的(de)四個(ge)角處的(de)咬口(kou)寬度(du)不(bu)相等；④ 手工(gong)咬口(kou)合縫(feng)受力不(bu)均。
