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，推薦防火閥能更有效隔熱降噪。消防(fang)排煙(yan)(yan)風機(ji)不能距離(li)隧(sui)(sui)(sui)道(dao)(dao)的邊壁(bi)太近，避免影響通(tong)(tong)風效果。通(tong)(tong)風系統從安全隧(sui)(sui)(sui)道(dao)(dao)向(xiang)通(tong)(tong)過橫(heng)通(tong)(tong)道(dao)(dao)向(xiang)事故隧(sui)(sui)(sui)道(dao)(dao)方向(xiang)送風，抑制煙(yan)(yan)氣(qi)進(jin)入(ru)(ru)橫(heng)通(tong)(tong)道(dao)(dao)及未(wei)發生事故的隧(sui)(sui)(sui)道(dao)(dao)，滿足疏(shu)散(san)人(ren)員迎著新風進(jin)入(ru)(ru)橫(heng)通(tong)(tong)道(dao)(dao)和(he)(he)安全隧(sui)(sui)(sui)道(dao)(dao)內，同時保(bao)證等待區域(yu)所需(xu)要的新鮮空氣(qi)。充分利用定點救援站處的斜井和(he)(he)隧(sui)(sui)(sui)道(dao)(dao)兩端的消防(fang)排煙(yan)(yan)風機(ji)作為送入(ru)(ru)新風和(he)(he)排煙(yan)(yan)的通(tong)(tong)道(dao)(dao)，通(tong)(tong)風必須維持橫(heng)通(tong)(tong)道(dao)(dao)口處于正(zheng)壓(ya)狀態，防(fang)止煙(yan)(yan)氣(qi)流向(xiang)通(tong)(tong)道(dao)(dao)內。

層(ceng)(ceng)高(gao)過高(gao)如何提(ti)高(gao)制冷效果(guo),解決方(fang)(fang)案：較(jiao)(jiao)之于(yu)(yu)常(chang)規(gui)層(ceng)(ceng)高(gao)的(de)(de)(de)房屋（一(yi)般(ban)為(wei)(wei)2.6-2.7米左右）。別墅(shu)的(de)(de)(de)層(ceng)(ceng)高(gao)一(yi)般(ban)都為(wei)(wei)3米甚至以上(shang)的(de)(de)(de)高(gao)度。此前提(ti)下中(zhong)央空調制冷和采(cai)暖(nuan)的(de)(de)(de)配比較(jiao)(jiao)之于(yu)(yu)一(yi)般(ban)層(ceng)(ceng)高(gao)的(de)(de)(de)房屋會更高(gao)。如一(yi)般(ban)平(ping)(ping)層(ceng)(ceng)的(de)(de)(de)配比為(wei)(wei)200w/平(ping)(ping)方(fang)(fang)。別墅(shu)為(wei)(wei)230-280w/平(ping)(ping)方(fang)(fang)。空調外機需要(yao)如何擺(bai)放(fang)較(jiao)(jiao)為(wei)(wei)合理,解決方(fang)(fang)案：別墅(shu)由于(yu)(yu)面積較(jiao)(jiao)大(da)(da)，較(jiao)(jiao)之于(yu)(yu)平(ping)(ping)層(ceng)(ceng)一(yi)般(ban)外機的(de)(de)(de)功率較(jiao)(jiao)大(da)(da)。體(ti)積也就較(jiao)(jiao)之平(ping)(ping)層(ceng)(ceng)會更大(da)(da)。一(yi)般(ban)的(de)(de)(de)擺(bai)放(fang)位(wei)(wei)置位(wei)(wei)于(yu)(yu)本身建(jian)筑的(de)(de)(de)自(zi)留機位(wei)(wei)或(huo)者(zhe)位(wei)(wei)于(yu)(yu)門口或(huo)者(zhe)陽(yang)臺花園的(de)(de)(de)平(ping)(ping)臺之上(shang)。鋪設可(ke)供平(ping)(ping)衡的(de)(de)(de)水(shui)泥臺面即可(ke)。
