style="text-indent:25px">迷宮式消聲器是在直管消聲器基礎(chǔ)上，插入一些吸聲障板，使聲波不斷的由一個小室繞行到另一個小室，從而增加了消聲效果，特別在中低頻率范圍，當(dāng)然阻力也要增加。迷宮式消聲器中的氣流速度不宜太高。蜂窩式消聲器的結(jié)構(gòu)特點(diǎn)類似于片式消聲器，只是為了進(jìn)一步減小每一個消聲器通道截面尺寸，把整個大的通道分成多個蜂窩式小的消聲通道。聲流式消聲器類似于折板式消聲器，只是為了減小阻力，把通道加工成聲流式。聲流式消聲器阻力較低，但是結(jié)構(gòu)較為復(fù)雜，加工難度較大。茂名消聲器有哪些消聲器用于減小排氣脈動，并盡可能降低排氣噪聲。</p><div

style="text-indent:25px">筒式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)焊有幾塊隔板，將消聲筒分成若干個消聲腔(N個膨脹室和1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(jī)的高溫廢氣以高速經(jīng)排氣管進(jìn)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(qiáng)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)流孔及筒芯通過，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，從而起到降低排氣噪聲的作用。</p><p style="text-indent:25px">消聲器用于減小排氣脈動，并盡可能降低排氣噪聲。消聲器的選用應(yīng)根據(jù)防火、防潮、防腐、潔凈度要求，安裝的空間位置，噪聲源頻譜特性，系統(tǒng)自然聲衰減，系統(tǒng)氣流再生噪聲，房間允許噪聲級，允許壓力損失，設(shè)備價格等諸多因素綜合考慮并根據(jù)實(shí)際情況有所偏重。一般的情況是: 消聲器的消聲量越大，壓力損失及價格越大；消聲量相同時，如果壓力損失越小，消聲器所占空間就越大。新型高效抗噴阻型系列消聲器設(shè)備被普遍使用于發(fā)電、化工、冶金、紡織等工業(yè)廠礦中用于各種型號鍋爐、汽機(jī)排汽；風(fēng)機(jī)；安全門等設(shè)備的消聲降音。排氣消聲器的主要是通過減低、衰減排氣壓力的脈動來消除噪聲的。</p><div
