        羅(luo)茨風(feng)(feng)(feng)機(ji)(ji)消音(yin)器(qi),又稱 羅(luo)茨風(feng)(feng)(feng)機(ji)(ji)消聲(sheng)器(qi)可用(yong)(yong)于(yu)(yu)降低各類風(feng)(feng)(feng)機(ji)(ji)的進(jin)/排氣噪(zao)聲(sheng),也可以(yi)用(yong)(yong)于(yu)(yu)對排氣管道及(ji)其(qi)(qi)它高壓風(feng)(feng)(feng)機(ji)(ji)的降噪(zao)。羅(luo)茨風(feng)(feng)(feng)機(ji)(ji)消音(yin)器(qi)/消聲(sheng)器(qi)主要用(yong)(yong)于(yu)(yu)各種系列的高壓離心通風(feng)(feng)(feng)機(ji)(ji),用(yong)(yong)于(yu)(yu)降低進(jin),出風(feng)(feng)(feng)口(kou)等空氣動力性(xing)噪(zao)聲(sheng)。本產品當(dang)用(yong)(yong)戶按要求(qiu)安(an)裝(zhuang)后,其(qi)(qi)極限噪(zao)聲(sheng)級將不(bu)超過85~90分貝。

工作原理:
         羅(luo)茨風(feng)(feng)機(ji)(ji)消(xiao)(xiao)音(yin)器(qi)(qi)/消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi)是根據阻(zu)聲(sheng)(sheng)(sheng)片(pian)消(xiao)(xiao)聲(sheng)(sheng)(sheng)原(yuan)理(li)所(suo)研制,該型(xing)消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi)聲(sheng)(sheng)(sheng)學性(xing)(xing)(xing)能(neng)優良,空氣(qi)動力性(xing)(xing)(xing)能(neng)良好;結構合(he)理(li),便于安裝,是一種大風(feng)(feng)量阻(zu)性(xing)(xing)(xing)蜂窩式(shi)消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi),抗性(xing)(xing)(xing)段采用(yong)了多室抗性(xing)(xing)(xing)膠直管通道及(ji)(ji)十字(zi)形(xing)吸(xi)聲(sheng)(sheng)(sheng)片(pian)形(xing)式(shi),從而保證了在(zai)較(jiao)寬頻(pin)帶(dai)范圍內具有(you)足夠的(de)消(xiao)(xiao)聲(sheng)(sheng)(sheng)量。消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi)結構由許多平行的(de)單元消(xiao)(xiao)聲(sheng)(sheng)(sheng)管排列組成,消(xiao)(xiao)聲(sheng)(sheng)(sheng)管之間填充多孔吸(xi)聲(sheng)(sheng)(sheng)材料,為(wei)減少氣(qi)流激發殼壁(bi)振(zhen)動而產生輻射聲(sheng)(sheng)(sheng),在(zai)外殼上設置了加強筋。風(feng)(feng)機(ji)(ji)消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi)、離心風(feng)(feng)機(ji)(ji)消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi)以(yi)及(ji)(ji)鼓引風(feng)(feng)機(ji)(ji)消(xiao)(xiao)音(yin)器(qi)(qi)的(de)形(xing)式(shi)均采用(yong)對中、高頻(pin)寬帶(dai)特性(xing)(xing)(xing)有(you)較(jiao)好效果(guo)的(de)阻(zu)性(xing)(xing)(xing)吸(xi)音(yin)降噪原(yuan)理(li),對低、中頻(pin)和(he)脈動特性(xing)(xing)(xing)時有(you)良好效果(guo)的(de)抗性(xing)(xing)(xing)消(xiao)(xiao)聲(sheng)(sheng)(sheng)降音(yin)原(yuan)理(li)以(yi)及(ji)(ji)微穿孔消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi)和(he)阻(zu)抗復合(he)式(shi)消(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)(qi)。
