消防排煙風機廠家產品由多個配件構成，比如說葉輪、機殼、軸承、主軸等等構成，而風機通風管不同的配件也起著不同的作用。首先對于葉輪而言，一般采用優質鍍鋅板制作而成的葉片，通過傾斜設計，與拉伸成型的前盤一起形成了更合理的流道，從而保證了葉輪的高效率。而軸承是帶鑄造座的外球面軸承，可以通過外球面配合調整同軸度的誤差。主軸一般采用45#鋼經調制處理后精車而成，保證足夠的光潔度和尺寸精。另外兩層板內部填充消聲材料，推薦風機通風管能更有(you)效隔熱降噪。消(xiao)防排(pai)煙(yan)風機(ji)不能距離(li)隧(sui)道(dao)(dao)(dao)(dao)的(de)(de)邊壁太近，避免(mian)影響通(tong)(tong)(tong)風效果。通(tong)(tong)(tong)風系統從安全隧(sui)道(dao)(dao)(dao)(dao)向(xiang)通(tong)(tong)(tong)過橫(heng)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)向(xiang)事故隧(sui)道(dao)(dao)(dao)(dao)方向(xiang)送(song)風，抑制(zhi)煙(yan)氣進入(ru)橫(heng)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)及未發生事故的(de)(de)隧(sui)道(dao)(dao)(dao)(dao)，滿足疏(shu)散人(ren)員(yuan)迎著新(xin)(xin)風進入(ru)橫(heng)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)和安全隧(sui)道(dao)(dao)(dao)(dao)內，同時保證等待區域(yu)所需要的(de)(de)新(xin)(xin)鮮空(kong)氣。充(chong)分(fen)利用定點救援站處的(de)(de)斜井(jing)和隧(sui)道(dao)(dao)(dao)(dao)兩端(duan)的(de)(de)消(xiao)防排(pai)煙(yan)風機(ji)作為(wei)送(song)入(ru)新(xin)(xin)風和排(pai)煙(yan)的(de)(de)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)，通(tong)(tong)(tong)風必須維持橫(heng)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)口(kou)處于正壓狀(zhuang)態(tai)，防止煙(yan)氣流向(xiang)通(tong)(tong)(tong)道(dao)(dao)(dao)(dao)內。
