畢節高品質不銹鋼通風管道價格

在葉(xie)輪(lun)運(yun)(yun)轉初期(qi)及(ji)所有(you)定期(qi)檢查的(de)(de)時候，只要一有(you)機會，都必(bi)須檢查葉(xie)輪(lun)是(shi)否(fou)出現(xian)裂(lie)紋、磨損、積塵(chen)等缺(que)陷。只要有(you)可(ke)(ke)能，都必(bi)須使葉(xie)輪(lun)保持清潔狀(zhuang)態，并定期(qi)用鋼絲刷(shua)刷(shua)去上面的(de)(de)積塵(chen)和銹皮等，因(yin)為(wei)隨(sui)著(zhu)運(yun)(yun)行時間的(de)(de)加(jia)長，這些(xie)灰塵(chen)由于不可(ke)(ke)能均勻地(di)附著(zhu)在葉(xie)輪(lun)上，而(er)造成葉(xie)輪(lun)平(ping)(ping)(ping)(ping)衡(heng)(heng)破壞，以(yi)至引起轉子振動。葉(xie)輪(lun)只要進行了(le)修理，就需要對其再(zai)作動平(ping)(ping)(ping)(ping)衡(heng)(heng)。如(ru)有(you)條件，可(ke)(ke)以(yi)使用便攜(xie)試動平(ping)(ping)(ping)(ping)衡(heng)(heng)儀在現(xian)場進行平(ping)(ping)(ping)(ping)衡(heng)(heng)。在作動平(ping)(ping)(ping)(ping)衡(heng)(heng)之前，必(bi)須檢查所有(you)緊(jin)定螺栓是(shi)否(fou)上緊(jin)。因(yin)為(wei)葉(xie)輪(lun)已經(jing)在不平(ping)(ping)(ping)(ping)衡(heng)(heng)狀(zhuang)態下運(yun)(yun)行了(le)一段(duan)時間，這些(xie)螺栓可(ke)(ke)能已經(jing)松動。

消防排煙機一般是采用離心式風機和軸流式風機兩種重要的型式。從消防排煙風機風量、風壓考慮來看，消防排煙風機是高比轉高效率的風機，更加的適合選用軸流風機。軸流式消防排煙風機有兩種設計型式，一種為電機與主氣流分離型式，另一種為電機置于主氣流之中。畢節不銹鋼通風管道根據煙氣溫度的不同，采用不同型式的消防排煙風機，溫度大于400℃時，采用電機與主氣流分離型式，溫度小于400℃大于150℃，兩種型式的電機都可以選擇，在溫度小于150℃的時候，采用電機置于主氣流之中。 軸流消防排煙風機的流量范圍從7200m？/h至110000m？/h，有不同型號的編制，不銹鋼通風管道用來滿足不(bu)同(tong)通風(feng)(feng)(feng)排(pai)煙(yan)(yan)(yan)(yan)(yan)流量(liang)的(de)需求。消(xiao)(xiao)防(fang)排(pai)煙(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)機可(ke)以根據壓(ya)力(li)情況的(de)不(bu)同(tong)分(fen)為(wei)(wei)兩(liang)種類型(xing)，一(yi)(yi)(yi)類為(wei)(wei)軸流式(shi)消(xiao)(xiao)防(fang)排(pai)煙(yan)(yan)(yan)(yan)(yan)機，其各(ge)機號的(de)壓(ya)力(li)在600Pa左(zuo)(zuo)右，另一(yi)(yi)(yi)類為(wei)(wei)斜流消(xiao)(xiao)防(fang)排(pai)煙(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)機，各(ge)機號的(de)壓(ya)力(li)在1000Pa左(zuo)(zuo)右。為(wei)(wei)了(le)滿足排(pai)煙(yan)(yan)(yan)(yan)(yan)量(liang)和通風(feng)(feng)(feng)換氣的(de)要(yao)求，消(xiao)(xiao)防(fang)排(pai)煙(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)機一(yi)(yi)(yi)般(ban)都設計了(le)雙速(su)型(xing)的(de)結構(gou)模式(shi)。低速(su)可(ke)以通風(feng)(feng)(feng)使用，高速(su)可(ke)以排(pai)放(fang)煙(yan)(yan)(yan)(yan)(yan)霧，這樣不(bu)但(dan)可(ke)以節約能(neng)源(yuan)同(tong)時又(you)降(jiang)低了(le)噪(zao)聲污染。
