style="text-indent:25px">消聲器的原理：消聲器一般由排氣管、連接螺套、消聲筒和筒芯等幾部分組成。在連接螺套里裝有油浸石棉密封圈，以防止排氣管和消聲筒之間的接口漏氣。消聲筒內(nèi)焊有7塊隔板，將消聲筒分成8個消聲腔（七個膨脹室和一個共振腔）在筒芯上面有倒三角形導流槽和許多小孔，當發(fā)動機的高溫廢氣以高速經(jīng)排氣管進入消聲器時，由于消聲筒的截面積逐漸增大，氣流得以膨脹，流速降低，強大的脈動噪聲得以衰減。當氣流繼續(xù)流經(jīng)各膨脹室時，由于隔板的阻擋，氣流只能從隔板上的節(jié)流了、及筒芯通過，于是氣流突然被壓縮，分成許多細流，后又突然得以膨脹，如此多次突變，聲能被有效衰減，從而起到降低排氣噪聲的作用。</p><p style="text-indent:25px">阻抗聲流型通風、排氣管道及風機消聲器結(jié)構(gòu)原理：根據(jù)對工業(yè)用各類風機運行現(xiàn)場噪聲源進行實際測試所取得的頻譜特性資料來確定在哪些頻譜范圍內(nèi)需要多大消聲量作為設(shè)計吸聲體及流體通道的主要依據(jù)，同時采用了具有較大吸聲材料飾面的狹矩形通道，以增強吸收效果。另，風機的噪聲源在較大噪聲級時，其頻譜值往往不止一種，而對不同頻譜帶，對其消聲量要求也不相同。為此系列通風管道消音器及鼓引風機消聲器均為阻抗聲流型，采用了對高、中頻噪聲起吸音消聲作用的阻式結(jié)構(gòu)及對中、低頻噪聲起消聲降音作用的抗式結(jié)構(gòu)，同時在阻式通道中采用了高頻及低頻兩種吸音消聲區(qū)，用以較大限度的增寬消聲頻帶，以實現(xiàn)良好的消聲降噪效果。消聲器的覆面材料容易破損，使吸聲材料外露或脫落，影響功能。制作時，釘覆面材料的泡釘應加墊片。</p><div
