1、通風管道的材料

用作通風管道的材料很多(duo)，但常用的主要有以下(xia)兩類(lei)：

（1）金屬薄板

金屬薄(bo)板是制作(zuo)(zuo)風(feng)管及部件的(de)主要材料(liao)。通常使用(yong)的(de)有普(pu)通薄(bo)鋼板、鍍鋅薄(bo)鋼板、不銹鋼鋼板、鋁板和(he)塑料(liao)復(fu)合(he)鋼板。它(ta)們的(de)優點是易于工業化加工制作(zuo)(zuo)、安裝方便(bian)、能承受較(jiao)高溫(wen)度。

1）普通薄鋼板

具有(you)良好的加(jia)工性能和結構(gou)強度，但其(qi)表面容易生銹，所(suo)以制作時應(ying)刷油(you)漆進行防腐(fu)處理。

通風(feng)(feng)機的(de)性(xing)能參數(shu)主要有(you)流量、壓(ya)(ya)(ya)力(li)、功(gong)(gong)(gong)率(lv)(lv)，通風(feng)(feng)管道(dao)安裝電話(hua)，效率(lv)(lv)和(he)(he)轉速。另外，白鐵(tie)通風(feng)(feng)管道(dao)，噪聲和(he)(he)振動(dong)的(de)大小也是通風(feng)(feng)機的(de)主要技術指標(biao)。流量也稱(cheng)風(feng)(feng)量，以單(dan)位時間(jian)內流經通風(feng)(feng)機的(de)氣體(ti)體(ti)積表(biao)示(shi)；壓(ya)(ya)(ya)力(li)也稱(cheng)風(feng)(feng)壓(ya)(ya)(ya)，是指氣體(ti)在(zai)通風(feng)(feng)機內壓(ya)(ya)(ya)力(li)升高值，通風(feng)(feng)管道(dao)加工，有(you)靜壓(ya)(ya)(ya)、動(dong)壓(ya)(ya)(ya)和(he)(he)全壓(ya)(ya)(ya)之(zhi)分；功(gong)(gong)(gong)率(lv)(lv)是指通風(feng)(feng)機的(de)輸入功(gong)(gong)(gong)率(lv)(lv)，即軸功(gong)(gong)(gong)率(lv)(lv)。

武漢誠運(yun)力(li)通通風(feng)管道工(gong)(gong)程有(you)限公司(si)，主要生產通風(feng)管道、風(feng)機(ji)風(feng)閥、凈化產品、風(feng)管工(gong)(gong)程、油煙凈化工(gong)(gong)程、冷(leng)風(feng)機(ji)系列、冷(leng)風(feng)機(ji)工(gong)(gong)程。

通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)有效(xiao)(xiao)(xiao)(xiao)功(gong)率(lv)(lv)與軸功(gong)率(lv)(lv)之比稱為效(xiao)(xiao)(xiao)(xiao)率(lv)(lv)。通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)全(quan)壓效(xiao)(xiao)(xiao)(xiao)率(lv)(lv)可達90%。 通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)未(wei)來的(de)發展將進一步提(ti)高通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)的(de)氣動效(xiao)(xiao)(xiao)(xiao)率(lv)(lv)、裝置效(xiao)(xiao)(xiao)(xiao)率(lv)(lv)和使用效(xiao)(xiao)(xiao)(xiao)率(lv)(lv)，以降(jiang)低電能(neng)消耗；用動葉可調(diao)的(de)軸流通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)代替大型(xing)離(li)心(xin)通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)；降(jiang)低通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)噪(zao)聲；提(ti)高排煙(yan)、排塵通(tong)(tong)(tong)(tong)風(feng)機(ji)(ji)葉輪和機(ji)(ji)殼的(de)耐磨性；實(shi)現變轉速調(diao)節(jie)和自動化調(diao)節(jie)。
