消防排煙風機有幾種狀態

消(xiao)(xiao)防(fang)(fang)排(pai)(pai)煙風(feng)(feng)(feng)機(ji)平時(shi)(shi)常開，火災時(shi)(shi)也是(shi)開啟(qi)狀態(tai)，但當煙氣溫度(du)達到280℃時(shi)(shi)消(xiao)(xiao)防(fang)(fang)排(pai)(pai)煙風(feng)(feng)(feng)機(ji)自(zi)動關閉，聯動已經開啟(qi)的(de)風(feng)(feng)(feng)機(ji)停止運行(xing)，消(xiao)(xiao)防(fang)(fang)報警主機(ji)聯動的(de)消(xiao)(xiao)防(fang)(fang)排(pai)(pai)煙風(feng)(feng)(feng)機(ji)在消(xiao)(xiao)防(fang)(fang)系統中都屬于(yu)防(fang)(fang)排(pai)(pai)煙系統。但消(xiao)(xiao)防(fang)(fang)排(pai)(pai)煙風(feng)(feng)(feng)機(ji)完成上述工作的(de)前提是(shi)消(xiao)(xiao)防(fang)(fang)排(pai)(pai)煙風(feng)(feng)(feng)機(ji)控制(zhi)柜(ju)置于(yu)自(zi)動工作狀態(tai)，消(xiao)(xiao)防(fang)(fang)排(pai)(pai)煙風(feng)(feng)(feng)機(ji)的(de)工作原理大致就這么(me)多。主要是(shi)起消(xiao)(xiao)防(fang)(fang)通(tong)風(feng)(feng)(feng)作用，注意當風(feng)(feng)(feng)機(ji)控制(zhi)柜(ju)置于(yu)手動狀態(tai)時(shi)(shi)，不會(hui)與消(xiao)(xiao)防(fang)(fang)報警系統聯動。

消防排煙(yan)風(feng)(feng)機不能距離隧(sui)道(dao)(dao)(dao)的(de)(de)邊(bian)壁太近，避免影響通(tong)(tong)(tong)(tong)風(feng)(feng)效果(guo)，充(chong)分利用定點救援站處的(de)(de)斜井(jing)和(he)隧(sui)道(dao)(dao)(dao)兩端的(de)(de)消防排煙(yan)風(feng)(feng)機作為送(song)入新風(feng)(feng)和(he)排煙(yan)的(de)(de)通(tong)(tong)(tong)(tong)道(dao)(dao)(dao)，通(tong)(tong)(tong)(tong)風(feng)(feng)必須維持橫(heng)通(tong)(tong)(tong)(tong)道(dao)(dao)(dao)口處于正(zheng)壓狀態，防止煙(yan)氣流向(xiang)通(tong)(tong)(tong)(tong)道(dao)(dao)(dao)內。通(tong)(tong)(tong)(tong)風(feng)(feng)系統從安全隧(sui)道(dao)(dao)(dao)向(xiang)通(tong)(tong)(tong)(tong)過橫(heng)通(tong)(tong)(tong)(tong)道(dao)(dao)(dao)向(xiang)事故隧(sui)道(dao)(dao)(dao)方向(xiang)送(song)風(feng)(feng)，抑制煙(yan)氣進入橫(heng)通(tong)(tong)(tong)(tong)道(dao)(dao)(dao)及未發生(sheng)事故的(de)(de)隧(sui)道(dao)(dao)(dao)，滿足(zu)疏散人員(yuan)迎著新風(feng)(feng)進入橫(heng)通(tong)(tong)(tong)(tong)道(dao)(dao)(dao)和(he)安全隧(sui)道(dao)(dao)(dao)內，同時(shi)保證等待區(qu)域所需要的(de)(de)新鮮空氣。

一(yi)般情(qing)況下(xia)，消防(fang)排(pai)(pai)煙風(feng)機(ji)應(ying)單獨安裝，排(pai)(pai)煙風(feng)機(ji)應(ying)位于排(pai)(pai)煙區的同(tong)一(yi)層(ceng)或下(xia)層(ceng)。

　　例(li)如在隧道(dao)內(nei)，滅火扇(shan)不應離(li)隧道(dao)側壁太(tai)近，以免影響通風效(xiao)果。

　　充分利用救援站的斜井和隧道(dao)兩端的滅火(huo)排(pai)煙風機作為新風送(song)煙通(tong)道(dao)。通(tong)風應(ying)在交叉通(tong)道(dao)開(kai)口處保(bao)持正壓，以防止產生煙霧(wu)。它(ta)流入通(tong)道(dao)。

　　通風(feng)系統將(jiang)安全(quan)(quan)隧(sui)道的(de)(de)空氣(qi)通過十字路口(kou)送入事(shi)故(gu)(gu)隧(sui)道，防止煙(yan)氣(qi)無事(shi)故(gu)(gu)進入十字路口(kou)和隧(sui)道，滿足疏散(san)人員進入十字路口(kou)和安全(quan)(quan)隧(sui)道的(de)(de)需求。保(bao)證清新(xin)的(de)(de)微風(feng)，同時(shi)也(ye)是(shi)一(yi)個(ge)等(deng)候區。新(xin)鮮空氣(qi)。根據事(shi)故(gu)(gu)情況，每個(ge)隧(sui)道區域采用(yong)不同的(de)(de)防災通風(feng)方式。
