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，推薦電動防火閥能更有效隔熱降(jiang)噪。消防(fang)(fang)(fang)排煙(yan)(yan)風(feng)(feng)機不能距離隧(sui)(sui)(sui)道(dao)的邊壁太近，避免影響通(tong)風(feng)(feng)效果。通(tong)風(feng)(feng)系(xi)統(tong)從(cong)安(an)全隧(sui)(sui)(sui)道(dao)向(xiang)(xiang)通(tong)過(guo)橫通(tong)道(dao)向(xiang)(xiang)事故隧(sui)(sui)(sui)道(dao)方向(xiang)(xiang)送風(feng)(feng)，抑制煙(yan)(yan)氣進入橫通(tong)道(dao)及(ji)未(wei)發(fa)生(sheng)事故的隧(sui)(sui)(sui)道(dao)，滿(man)足疏散人員迎著新風(feng)(feng)進入橫通(tong)道(dao)和(he)(he)安(an)全隧(sui)(sui)(sui)道(dao)內(nei)，同時保(bao)證等(deng)待區域所需要的新鮮空氣。充分利(li)用定(ding)點救援站處的斜井和(he)(he)隧(sui)(sui)(sui)道(dao)兩端的消防(fang)(fang)(fang)排煙(yan)(yan)風(feng)(feng)機作為送入新風(feng)(feng)和(he)(he)排煙(yan)(yan)的通(tong)道(dao)，通(tong)風(feng)(feng)必(bi)須(xu)維持橫通(tong)道(dao)口處于(yu)正壓(ya)狀態(tai)，防(fang)(fang)(fang)止煙(yan)(yan)氣流向(xiang)(xiang)通(tong)道(dao)內(nei)。
