style="text-indent:25px">氣缸消聲器的定義：消音器是一種允許氣流通過而能使聲能衰減的裝置，能夠降低氣流通道上的空氣動力性噪聲。氣缸消聲器的選擇方法：具有較好的消聲性能，即要求消聲器具有較好的消聲頻率特性，噪聲一般控制在74~80dB之間(當供氣為0.6MPa,距離為1m時測得的噪聲）具有良好的空氣動力性能，消聲器對氣流的阻力損失要小結構簡單，便于加工，經濟耐用，無再生噪聲。在設計和選擇消聲器時，潮州消聲器，應合理選擇通過消聲器的氣流速度。對空調系統(tǒng)，潮州消聲器，潮州消聲器，流過的氣流速度可取≤6m/s;對一般系統(tǒng)宜取6~10m/s;對工業(yè)鼓風機或其他氣動設備可取10~20m/5s;對高壓排空消聲器則可大于20m/s。折板式消聲器是在片式消聲器的基礎上，增加氣流通道的長度和彎曲。潮州消聲器</p><div

style="text-indent:25px">共振腔消聲器。共振腔消聲器消聲原理是利用聲波頻率與共振腔固有頻率一致時對聲能的衰減達到較大進行消聲。與擴張室消聲器相比，共振腔消聲器具有消聲頻帶較窄，在共振頻率附近消聲量較大的特點，適用于具有單峰值頻率、且峰值較突出的高噪聲場合。設計時要求共振腔消聲器的共振頻率與聲波的主頻率一致。干涉型消聲器。干涉型消聲器是利用支管長度比主管長度長，并且多出的長度正好是1/2聲波波長的奇數(shù)倍，這樣支管聲波與主管聲波在振幅上相等，而在相位上相差180°的奇數(shù)倍，從而達到相互干涉而抵消，來實現(xiàn)消聲的目的。干涉型消聲器適用于消減某保持不變的單一頻率的噪聲，對于寬頻帶噪聲，這種型式消聲器無效。??潮州消聲器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。</p><div

style="text-indent:25px">抗性式消聲器是由突變界面的管和室組合而成的，好像是一個聲學濾波器，與電學濾波器相似，每一個帶管的小室是濾波器的一個網孔，管中的空氣質量相當于電學上的電感和電阻，稱為聲質量和聲阻。小室中的空氣體積相當于電學上的電容，稱為聲順。與電學濾波器類似，每一個帶管的小室都有自己的固有頻率。當包含有各種頻率成分的聲波進入個短管時，只有在個網孔固有頻率附近的某些頻率的聲波才能通過網孔到達第二個短管口，而另外一些頻率的聲波則不可能通過網孔．只能在小室中來回反射，因此，我們稱這種對聲波有濾波功能的結構為聲學濾波器。選取適當?shù)墓芎褪疫M行組合．就可以濾掉某些頻率成分的噪聲，從而達到消聲的目的?？剐韵暺鬟m用于消除中、低頻噪聲。</p><p style="text-indent:25px">阻抗式消聲器：現(xiàn)有的消聲器，大多采用阻抗復合型消聲原理。由于結構復雜、重量大、高溫氧化吸聲填料，高速氣流沖擊吸聲填料，水氣滲透吸聲填料等原因，消聲器很容易出現(xiàn)維修頻繁、消聲效果差，使用周期短等情況。而這歷來是消音器的設計難點，微穿孔消聲器則綜合了較合理的消聲原理所設計解決了上述問題，取得了良好效果。微穿孔消聲器消聲器不使用任何阻性吸聲填料，采用微穿小孔多空腔結構，高壓氣流在消聲器內經多次控流進入空腔體，逐級改變原氣流的聲頻。阻力損失小，消聲頻帶寬，工作時不起塵。不怕油霧、水氣。耐高溫、耐高速氣流沖擊。使環(huán)境噪聲符合國家《工業(yè)企業(yè)噪聲衛(wèi)生標準》。普遍用于石油、化工、冶金、紡織等行業(yè)。安全閥消聲器排汽消聲器可達25分貝以上。</p><div

style="text-indent:25px">抗性消聲器可以分為5種基本形式：擴張室消聲器、共鳴型消聲器、干涉型消聲器、損耗型消聲器和文氏型消聲器。消聲原理：擴張室消聲器一是利用管道的裁面突變，即聲阻抗的變化使沿管道傳播的聲波向聲源方向反射回去；二是利用擴張室和內插管的長度，使向前傳播的波和管子不同界面反射的聲波差一個180度的相位、從而使二者振幅相等、相位相反，互相干涉，達到較理想的消聲效果。共鳴型消聲器常用于消除管道傳播的低頻(350Hz以下)噪聲。干涉型消聲器的消聲原理足將聲波分成兩路，在管道上裝設一排通管，使管道長度為通管長度的2倍。管道長度等于要消除的聲波的波長，那么通管的長度則為二分之一波長。這樣聲波當通過兩種不同長度的途徑時，在管道與通管匯合處將產生振幅相等，位移相反的2種聲波，彼此互相干涉，從而降低噪聲。消聲器分為阻性消聲器、抗性消聲器、阻抗復合式消聲器、微穿孔板消聲器、小孔消聲器和有源消聲器。潮州消聲器</p><p style="text-indent:25px">消音器實際上在解決燃氣噪音。潮州消聲器</p><p style="text-indent:25px">消聲器的消聲原理是利用腔與管的適當組合，來達到兩種作用來消聲的：一是利用管道截面突變(即聲抗的變化)使沿管道傳播的聲波向聲源方向反射回去，從而使聲能反射回原處；二是利用幾個界面的反射，使原來個向前傳播的聲波又回到原點，并再次折回向前傳播，該點與尚未被反射的第二個向前傳播的聲波匯合，而且兩者在振幅上相等，在相位上差180度的奇數(shù)倍，從而互相干涉而抵消。風機式消聲器主要適用于降低羅茨系列、軸流系列風機的進排氣噪聲，也可以用于對排氣管道及其它高壓風機的降噪，消聲量15-30dB，壓力損失少于500Pa。潮州消聲器</p><p
