style="text-indent:25px">消音器的種類很多，但究其消聲機理，又可以把它們分為六種主要的類型，即阻性消音器、抗性消音器、阻抗復合式消音器、微穿孔板消音器、小孔消音器和有源消音器。節(jié)流降壓消聲器，利用節(jié)流降壓原理制成的消聲器。一般用于噴氣噪聲的治理。根據(jù)噴氣量的大小，設計通流面積，使高壓氣體通過節(jié)流孔板時，壓力降低。因噴氣噪聲的聲功率級與氣體壓力降的高次方成正比（見工業(yè)噪聲），若用多級節(jié)流孔板串聯(lián)，使原來的一次降壓變?yōu)橹鸩浇祲?，便可使輻射的噪聲有效降低。?jié)流降壓消聲器的消聲量約為15～25dB(A)。具有結(jié)構(gòu)簡單、降噪效果好的優(yōu)點，但耗用鋼材較多。</p><p 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。微穿孔板式消聲器可以控制消聲器的頻譜性能。</p><div

style="text-indent:25px">消聲器的機殼或管道輻射的噪聲可能傳入消聲器后端，致使消聲效果下降，必要時，可在消聲器外殼或部分管道上做隔聲處理。消聲器法蘭和風機法蘭連接處應加彈性墊并注意密封，以免漏聲、漏氣，同時也能減少剛性連接的振動傳聲。在通風空調(diào)系統(tǒng)中，消聲器應盡量安裝于靠近使用房間的地方。消聲器片間流速應適當。風機消聲器片間平均流速可認為與風機管道流速相等。用于民用建筑，消聲器片間流速通常取3-12m/s；工業(yè)方面，消聲器片間流速通常取12-25m/s，較大不得超過30m/s。流速不同，消聲器護面結(jié)構(gòu)應不同。平均流速小于10m/s時，多孔吸聲材料的護面可用防火布或金屬絲網(wǎng)罩起來；平均流速為10-23m/s時，可選用金屬穿孔板護面；當平均流速為23-45m/s時，可選用玻璃絲布和金屬穿孔板護面；當平均流速為45-120m/s時，可采用雙層金屬穿孔板和鋼絲棉護面，穿孔率應大于20%。玉林消聲器多少錢</p><p
