江蘇倍佳節能環保(bao)設(she)備有(you)限公司一家(jia)從事(shi)工(gong)業(ye)風機消(xiao)(xiao)音(yin)器的研(yan)制、生(sheng)產、銷售的廠家(jia)，各(ge)類風機消(xiao)(xiao)音(yin)器要想消(xiao)(xiao)音(yin)降噪效(xiao)果好。工(gong)業(ye)風機消(xiao)(xiao)音(yin)器為片式阻性消(xiao)(xiao)聲器，維修更換方便，值得你的青睞！
工業風機消(xiao)音器主(zhu)要是(shi)建立在(zai)“小孔噴注”理(li)論(lun)和阻(zu)抗擴(kuo)(kuo)容吸聲(sheng)(sheng)的(de)消(xiao)聲(sheng)(sheng)原(yuan)理(li)，鍋爐蒸(zheng)(zheng)汽排放一(yi)般流(liu)(liu)速(su)快，氣流(liu)(liu)噪(zao)(zao)聲(sheng)(sheng)高，需先以通(tong)孔擴(kuo)(kuo)流(liu)(liu)，經過多次(ci)通(tong)孔后的(de)蒸(zheng)(zheng)汽在(zai)抗性擴(kuo)(kuo)張室得到降(jiang)壓(ya)(ya)(ya)降(jiang)流(liu)(liu)，氣流(liu)(liu)再經小孔噴出，噴出后其各倍頻(pin)帶(dai)的(de)聲(sheng)(sheng)功(gong)率(lv)已降(jiang)低，而(er)聲(sheng)(sheng)壓(ya)(ya)(ya)級的(de)頻(pin)率(lv)被推高到20000Hz以上(shang)范圍，其噪(zao)(zao)聲(sheng)(sheng)大為削弱(ruo)，但部分頻(pin)率(lv)的(de)二(er)次(ci)噪(zao)(zao)音還需要進一(yi)步消(xiao)聲(sheng)(sheng)，我們在(zai)擴(kuo)(kuo)張室外加(jia)裝(zhuang)阻(zu)性吸聲(sheng)(sheng)棉結構，羅茨鼓風機出入口消(xiao)聲(sheng)(sheng)器，煙氣排氣消(xiao)聲(sheng)(sheng)裝(zhuang)置系(xi)根據(ju)降(jiang)壓(ya)(ya)(ya)體所(suo)發出的(de)剩余噪(zao)(zao)聲(sheng)(sheng)的(de)頻(pin)譜特性所(suo)設(she)計，用以有效地吸收剩余噪(zao)(zao)聲(sheng)(sheng)。
工業風(feng)(feng)機(ji)(ji)消(xiao)(xiao)(xiao)音器(qi)為片式阻性消(xiao)(xiao)(xiao)聲器(qi)，維修(xiu)更換(huan)方便(bian)，分為A、B、C三種(zhong)片型，適應不同的消(xiao)(xiao)(xiao)聲頻率特性，可按需(xu)要選(xuan)用(yong)(yong)，并有單節(jie)1m及1.5m兩種(zhong)自組成(cheng)1m，1.5m，2m，2.5m，3m五種(zhong)長(chang)度(du)獲得合理消(xiao)(xiao)(xiao)聲量。工業風(feng)(feng)機(ji)(ji)消(xiao)(xiao)(xiao)聲器(qi)排(pai)氣(qi)消(xiao)(xiao)(xiao)聲器(qi)適用(yong)(yong)于(yu)工業與民(min)用(yong)(yong)建筑中(zhong)具有一般(ban)用(yong)(yong)途的中(zhong)低(di)壓離心通(tong)(tong)(tong)風(feng)(feng)機(ji)(ji)配(pei)套。例如：4-72，4-73，5-48，6-48等系(xi)列中(zhong)各(ge)機(ji)(ji)號的風(feng)(feng)機(ji)(ji)，在(zai)作(zuo)為通(tong)(tong)(tong)風(feng)(feng)換(huan)氣(qi)，鍋爐鼓風(feng)(feng)使用(yong)(yong)中(zhong)都可以用(yong)(yong)本系(xi)列消(xiao)(xiao)(xiao)聲器(qi)作(zuo)為降低(di)風(feng)(feng)機(ji)(ji)進、排(pai)氣(qi)噪聲。當消(xiao)(xiao)(xiao)聲器(qi)通(tong)(tong)(tong)過流(liu)量在(zai)m3/h范圍內，消(xiao)(xiao)(xiao)聲器(qi)耐壓<8000Pa，消(xiao)(xiao)(xiao)聲量大(da)于(yu)25dB(A)。
工業風機消(xiao)音器(qi)是根據阻聲(sheng)(sheng)(sheng)(sheng)片(pian)消(xiao)聲(sheng)(sheng)(sheng)(sheng)原理(li)所研(yan)制，該型消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)聲(sheng)(sheng)(sheng)(sheng)學性(xing)能優良，空氣動(dong)力性(xing)能良好；結(jie)構合理(li)，便于安裝，是一種大風量(liang)阻性(xing)蜂窩式消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)，抗(kang)(kang)性(xing)段(duan)采用了(le)(le)多(duo)室抗(kang)(kang)性(xing)膠直管(guan)通道及十字形吸聲(sheng)(sheng)(sheng)(sheng)片(pian)形式，從而保證了(le)(le)在(zai)較寬頻帶(dai)范圍內具有足夠的消(xiao)聲(sheng)(sheng)(sheng)(sheng)量(liang)。該系列(lie)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)結(jie)構由許多(duo)平行的單元消(xiao)聲(sheng)(sheng)(sheng)(sheng)管(guan)排列(lie)組成，消(xiao)聲(sheng)(sheng)(sheng)(sheng)管(guan)之間填充(chong)多(duo)孔(kong)吸聲(sheng)(sheng)(sheng)(sheng)材料，為減少氣流激(ji)發殼壁(bi)振(zhen)動(dong)而產生輻(fu)射聲(sheng)(sheng)(sheng)(sheng)，在(zai)外殼上設置(zhi)了(le)(le)加(jia)強(qiang)筋。
