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(dǎo)流槽和許多小孔，當(dāng)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(dāng)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(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。</p><p style="text-indent:25px">消聲器和消聲靜壓箱的區(qū)別：當(dāng)噪聲源在室內(nèi)產(chǎn)生的聲壓級高于允許的噪聲標(biāo)準(zhǔn)時，就需要根據(jù)各頻帶要求消除的聲壓級選擇的消聲裝置，消除在室內(nèi)的噪聲標(biāo)準(zhǔn)之上的那部分聲能。消聲器是根據(jù)不同的消聲原理設(shè)計成的管道構(gòu)件，按所采用的消聲原理可分為阻性消聲器、抗性消聲器、共振消聲器和原合消聲器等類型。而消聲靜壓箱在風(fēng)機出口或空氣分布器前設(shè)置內(nèi)貼有吸聲材料的靜壓箱，除了可以穩(wěn)定氣流外，還具有消聲的作用。消聲靜壓箱的消聲量與吸聲材料的性能、箱內(nèi)貼吸聲材料的面積以及出口側(cè)風(fēng)管的面積等因素有關(guān)。微穿孔消聲器阻力損失小，消聲頻帶寬，工作時不起塵。</p><div
