3c消防排煙風機歸于(yu)風(feng)(feng)(feng)機(ji)(ji)(ji)的一種(zhong)，在(zai)實踐運(yun)用中(zhong)首要起(qi)到排(pai)煙(yan)(yan)通(tong)風(feng)(feng)(feng)的效果。但是(shi)在(zai)運(yun)用過程中(zhong)，由(you)于(yu)一些(xie)3c消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)設備不(bu)到位，極易影響其通(tong)風(feng)(feng)(feng)效果。3c消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)噪聲的聲級，不(bu)只與(yu)其風(feng)(feng)(feng)機(ji)(ji)(ji)的結構辦(ban)法有(you)關(guan)，并且還(huan)同(tong)其作(zuo)業情況(由(you)全壓(ya)和風(feng)(feng)(feng)量選(xuan)擇)有(you)關(guan)。不(bu)同(tong)系列、不(bu)同(tong)類型(xing)的風(feng)(feng)(feng)機(ji)(ji)(ji)，其聲級是(shi)不(bu)一樣的。同(tong)一3c消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)，在(zai)不(bu)同(tong)工況下，其聲級也是(shi)不(bu)同(tong)的。3c消(xiao)防(fang)排(pai)煙(yan)(yan)風(feng)(feng)(feng)機(ji)(ji)(ji)廠家(jia)的風(feng)(feng)(feng)機(ji)(ji)(ji)作(zuo)業在(zai)高功率點時，聲級往往取量低值。

　　為了更(geng)好(hao)表征風(feng)(feng)(feng)(feng)機(ji)的噪聲(sheng)(sheng)(sheng)(sheng)功用(yong)，呈現了比(bi)(bi)A級(ji)這(zhe)個概念。比(bi)(bi)A聲(sheng)(sheng)(sheng)(sheng)級(ji)是指(zhi)通(tong)風(feng)(feng)(feng)(feng)機(ji)在(zai)單位(wei)流量(liang)(liang)(1米/分)和單位(wei)全壓(1毫米水柱)下(xia)所(suo)發生的A聲(sheng)(sheng)(sheng)(sheng)級(ji)。。同(tong)(tong)一(yi)風(feng)(feng)(feng)(feng)機(ji)在(zai)不(bu)同(tong)(tong)工(gong)況下(xia)的比(bi)(bi)A聲(sheng)(sheng)(sheng)(sheng)級(ji)是不(bu)同(tong)(tong)的。在(zai)高(gao)功率點上，比(bi)(bi)A聲(sheng)(sheng)(sheng)(sheng)級(ji)取量(liang)(liang)低值。不(bu)同(tong)(tong)系(xi)列(lie)的風(feng)(feng)(feng)(feng)機(ji)在(zai)額(e)外工(gong)況下(xia)的比(bi)(bi)A聲(sheng)(sheng)(sheng)(sheng)級(ji)表征了該系(xi)列(lie)風(feng)(feng)(feng)(feng)機(ji)噪聲(sheng)(sheng)(sheng)(sheng)級(ji)的凹凸(tu)和產品(pin)質量(liang)(liang)的好(hao)壞。所(suo)以現在(zai)國(guo)內外多選用(yong)比(bi)(bi)A聲(sheng)(sheng)(sheng)(sheng)級(ji)作為風(feng)(feng)(feng)(feng)機(ji)噪聲(sheng)(sheng)(sheng)(sheng)的限值指(zhi)標。同(tong)(tong)一(yi)系(xi)列(lie)不(bu)同(tong)(tong)類型的風(feng)(feng)(feng)(feng)機(ji)，其比(bi)(bi)A聲(sheng)(sheng)(sheng)(sheng)級(ji)大體附(fu)近。3c消防(fang)排煙風(feng)(feng)(feng)(feng)機(ji)加(jia)工(gong)精度愈高(gao)，氣動功用(yong)愈好(hao)，比(bi)(bi)A聲(sheng)(sheng)(sheng)(sheng)級(ji)愈低。

　　3c消(xiao)防(fang)排煙風(feng)機(ji)廠(chang)家告(gao)訴您操(cao)(cao)控(kong)風(feng)機(ji)噪聲(sheng)(sheng)的(de)常用辦法是(shi)在(zai)風(feng)機(ji)的(de)進、出口處設(she)備阻(zu)性消(xiao)聲(sheng)(sheng)器。關于有(you)更高降噪要求的(de)場合，能夠選用消(xiao)聲(sheng)(sheng)隔聲(sheng)(sheng)箱(xiang)，并(bing)在(zai)機(ji)組與地基之(zhi)間組織減震(zhen)器。選用上述辦法，一般(ban)可獲得(de)顯(xian)著的(de)降噪效果。國內(nei)現已有(you)許多噪聲(sheng)(sheng)操(cao)(cao)控(kong)設(she)備廠(chang)，可提供各類風(feng)機(ji)的(de)消(xiao)聲(sheng)(sheng)噪器、消(xiao)聲(sheng)(sheng)隔聲(sheng)(sheng)箱(xiang)及(ji)減震(zhen)器。3c消(xiao)防(fang)排煙風(feng)機(ji)的(de)噪聲(sheng)(sheng)問(wen)題，從技術上來講，在(zai)我國基本上已可得(de)到(dao)有(you)用的(de)操(cao)(cao)控(kong)，并(bing)且低噪聲(sheng)(sheng)風(feng)機(ji)也已初步呈現。
