在日常的生活中我(wo)(wo)們經常可以見到消防(fang)排煙風機，它的出(chu)現(xian)(xian)給我(wo)(wo)們帶(dai)來了很大的便(bian)利，但是在應用的過程中會出(chu)現(xian)(xian)噪聲(sheng)，那么出(chu)現(xian)(xian)這種現(xian)(xian)象我(wo)(wo)們該(gai)如(ru)何進行(xing)控制呢？下面由小編來給大家簡(jian)單介(jie)紹一下其相關知識點。

    1、一般(ban)(ban)來說，前向葉(xie)片消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)，其(qi)比A聲(sheng)(sheng)(sheng)(sheng)級低(di)(di)于(yu)(yu)2dBA；后(hou)向板型(xing)葉(xie)片消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)，低(di)(di)于(yu)(yu)30dBA機(ji)(ji)(ji)翼型(xing)葉(xie)片消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)，低(di)(di)于(yu)(yu)25dBA；消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)，低(di)(di)于(yu)(yu)38bBA。在不同(tong)工況下，消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)噪(zao)聲(sheng)(sheng)(sheng)(sheng)的(de)(de)聲(sheng)(sheng)(sheng)(sheng)級由下式(shi)斷(duan)定(ding)：LA=LSA+10LgQP dBA；式(shi)中：La----風(feng)(feng)(feng)機(ji)(ji)(ji)進氣(qi)(qi)口(kou)(或(huo)(huo)出(chu)氣(qi)(qi)口(kou))的(de)(de)A聲(sheng)(sheng)(sheng)(sheng)級，dBA；Lsa----風(feng)(feng)(feng)機(ji)(ji)(ji)進氣(qi)(qi)口(kou)(或(huo)(huo)出(chu)氣(qi)(qi)口(kou))的(de)(de)比A聲(sheng)(sheng)(sheng)(sheng)級，dBA；Q----風(feng)(feng)(feng)量，米(mi)3/分；P----風(feng)(feng)(feng)機(ji)(ji)(ji)全(quan)壓，毫(hao)米(mi)水柱操(cao)(cao)控消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)噪(zao)聲(sheng)(sheng)(sheng)(sheng)的(de)(de)常用(yong)(yong)辦(ban)法是(shi)在風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)進、出(chu)口(kou)處裝置阻(zu)性消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)。關于(yu)(yu)有更(geng)高降噪(zao)要(yao)求的(de)(de)場合(he)，能夠選用(yong)(yong)消(xiao)聲(sheng)(sheng)(sheng)(sheng)隔聲(sheng)(sheng)(sheng)(sheng)箱(xiang)，并在機(ji)(ji)(ji)組與地基之(zhi)間(jian)安置減震器(qi)。采(cai)納上(shang)述辦(ban)法，一般(ban)(ban)可獲得顯著的(de)(de)降噪(zao)作用(yong)(yong)。2、國內現已(yi)有許多(duo)噪(zao)聲(sheng)(sheng)(sheng)(sheng)操(cao)(cao)控設備廠，可提供各類消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)消(xiao)聲(sheng)(sheng)(sheng)(sheng)噪(zao)器(qi)、消(xiao)聲(sheng)(sheng)(sheng)(sheng)隔聲(sheng)(sheng)(sheng)(sheng)箱(xiang)及減震器(qi)。消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)噪(zao)聲(sheng)(sheng)(sheng)(sheng)問題，從(cong)技術上(shang)來講，在我國基本上(shang)已(yi)可得到有效的(de)(de)操(cao)(cao)控，并且消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)也(ye)已(yi)開(kai)端(duan)呈現。可是(shi)，關于(yu)(yu)有特殊要(yao)求的(de)(de)風(feng)(feng)(feng)機(ji)(ji)(ji)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)，如(ru)要(yao)求防(fang)水、防(fang)潮、耐(nai)高溫或(huo)(huo)防(fang)塵(chen)等(deng)，尚有許多(duo)研(yan)究作業值得開(kai)展(zhan)。
