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(gè)消聲腔（七個(gè)膨脹室和一個(gè)共振腔）在筒芯上面有倒三角形導(dǎo)流槽和許多小孔，當(dāng)發(fā)動(dòng)機(jī)的高溫廢氣以高速經(jīng)排氣管進(jìn)入消聲器時(shí)，由于消聲筒的截面積逐漸增大，氣流得以膨脹，流速降低，強(qiáng)大的脈動(dòng)噪聲得以衰減。當(dāng)氣流繼續(xù)流經(jīng)各膨脹室時(shí)，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(guò)，于是氣流突然被壓縮，分成許多細(xì)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。揭陽(yáng)消聲器廠折板式消聲器是在片式消聲器的基礎(chǔ)上，增加氣流通道的長(zhǎng)度和彎曲。</p><div

style="text-indent:25px">一般采用靜態(tài)消聲量來(lái)表示消聲器的消聲效果，因?yàn)殪o態(tài)消聲量是一個(gè)定值，而動(dòng)態(tài)消聲量受氣流速度的影響，是一個(gè)不定值，故評(píng)價(jià)指標(biāo)以用靜態(tài)消聲量為宜。當(dāng)聲源經(jīng)靜態(tài)消聲后的剩余聲級(jí)（簡(jiǎn)稱靜態(tài)出口聲級(jí)）大于消聲器氣流噪聲級(jí)時(shí)，消聲器的動(dòng)態(tài)、靜態(tài)消聲量基本一致，不受氣流的影響；當(dāng)消聲器靜態(tài)出口聲級(jí)低于消聲器氣流噪聲級(jí)時(shí)，則消聲器的動(dòng)態(tài)消聲量低于靜態(tài)消聲量，其差值隨流速的增加而增大；當(dāng)氣流噪聲級(jí)大于消聲器入口聲級(jí)時(shí)，此時(shí)消聲器不僅不能消聲，反而變成了一個(gè)噪聲放大器。為解決靜態(tài)和動(dòng)態(tài)消聲量可能不一致的問(wèn)題，有些消聲器產(chǎn)品已采用靜態(tài)消聲量和氣流噪聲級(jí)兩個(gè)指標(biāo)同時(shí)表示產(chǎn)品的聲學(xué)性能。</p><p style="text-indent:25px">直管式消聲器是結(jié)構(gòu)較簡(jiǎn)單的一種阻性消聲器，吸聲材料直接布置在管道內(nèi)壁、根據(jù)管道的需要可以是圓形或方形。由于只有一個(gè)氣流通道，適合流量不大的情況使用。片式消聲器適合較大風(fēng)量和較大管道情況使用。由于把大的管道分成多個(gè)尺寸較小的消聲通道，即可以保持較大的氣流通道，又增加了氣流通道的吸聲材料的周長(zhǎng)，使之具有較好的消聲效果。折板式消聲器是在片式消聲器的基礎(chǔ)上，增加氣流通道的長(zhǎng)度和彎曲，增加噪聲和吸聲材料的接觸時(shí)間，減少高頻噪聲的直接投射，適當(dāng)?shù)卦黾恿讼曅Ч?，但是和片式消聲器比較，阻力也要增加。微穿孔消聲器耐高溫、耐高速氣流沖擊。</p><div
