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，而電動防火閥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，值得信賴的電動防火閥能更(geng)有效(xiao)隔熱降(jiang)噪。消(xiao)防排煙風機不能距離(li)隧道(dao)的(de)(de)邊壁太近(jin)，避免影(ying)響(xiang)通(tong)(tong)(tong)風效(xiao)果。通(tong)(tong)(tong)風系統從安(an)全隧道(dao)向(xiang)通(tong)(tong)(tong)過橫(heng)通(tong)(tong)(tong)道(dao)向(xiang)事故(gu)隧道(dao)方向(xiang)送風，抑制煙氣進入橫(heng)通(tong)(tong)(tong)道(dao)及未發生事故(gu)的(de)(de)隧道(dao)，滿足(zu)疏(shu)散人(ren)員(yuan)迎著(zhu)新(xin)風進入橫(heng)通(tong)(tong)(tong)道(dao)和安(an)全隧道(dao)內，同(tong)時保(bao)證等待(dai)區域所需要(yao)的(de)(de)新(xin)鮮空氣。充分利用(yong)定點救援站處(chu)的(de)(de)斜(xie)井(jing)和隧道(dao)兩(liang)端(duan)的(de)(de)消(xiao)防排煙風機作為送入新(xin)風和排煙的(de)(de)通(tong)(tong)(tong)道(dao)，通(tong)(tong)(tong)風必須維持橫(heng)通(tong)(tong)(tong)道(dao)口處(chu)于正壓狀態，防止(zhi)煙氣流向(xiang)通(tong)(tong)(tong)道(dao)內。
