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(shè)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。??防城港消聲器報價消聲器一般應(yīng)設(shè)于空調(diào)機房和空調(diào)房間之間考近空調(diào)機房，且氣流穩(wěn)定的直管段上。</p><div

style="text-indent:25px">蒸汽消聲器可滿足各種參數(shù)鍋爐向空排汽、安全閥排汽及鍋爐送風機進口的降噪消聲要求，同時也普遍用于石油、化工、冶金、紡織等工業(yè)的鍋爐蒸汽排放及其它氣體消聲排放，使之達到工業(yè)企業(yè)噪聲標準要求。其特點如下：采用多級消聲，消聲量大，排汽消聲器可達35～40分貝；安全閥消聲器可達25分貝以上；風機消聲器可達30～40分貝以上。體積小，重量輕，安裝簡便，易維護。ZXP、ZXA系列，筒體采用較好不銹鋼，具有足夠高的強度和耐腐蝕性。能單獨固定、吸收排汽管道的垂直及水平熱位移，使排汽管道不因消聲器的安裝而受到額外的荷載，保證排汽管道在熱能工作下的安全性。</p><p style="text-indent:25px">消音器實際上在解決燃氣噪音。典型消音器的原理，是在內(nèi)部設(shè)置多個碗型結(jié)構(gòu)，讓出膛高溫燃氣在每一個碗型結(jié)構(gòu)形成的密閉空腔內(nèi)逐級膨脹釋放能量，并因此在較終出消音器口時明顯降低速度和能量，因此達到降低燃氣出膛噪音的效果。發(fā)射的主要噪音來源，從大到小排列。高壓燃氣出膛時膨脹產(chǎn)生的噪音和超音速燃氣產(chǎn)生的激波聲，在沒有加消音器的時候，平常聽到的聲主要都是來自這個來源，甚至說全部來自它，因為這個聲音是遠大于其他兩個來源的。我們后文簡稱這一來源為燃氣噪音。如果發(fā)射的是超音速彈，彈丸出膛后空氣中超音速飛行產(chǎn)生的激波噪音。相對個來源，這個聲音較小，但音量也很大，而且音色很尖銳。后文簡稱為激波噪音。擊發(fā)和機循環(huán)完成拋殼上膛本身伴隨著金屬部件之間的碰撞，這個聲音又明顯小于前兩者，但也不可忽略。后文簡稱為機噪音。安全閥類排汽消聲器一般選購通孔阻散型消聲器，該消聲器一般外殼體為碳鋼，接管及內(nèi)部材質(zhì)為不銹鋼。</p><div

style="text-indent:25px">在空調(diào)系統(tǒng)中靜壓箱和消聲器是常見的，是用于通風設(shè)備出入口、多支風管匯合或分支處，為了保證氣流均勻，一般應(yīng)設(shè)靜壓箱。靜壓箱的工作原理是依據(jù)截面的變化，將氣流的動壓轉(zhuǎn)變?yōu)闅饬鞯撵o壓。靜壓箱一般根據(jù)所需厚度的鋼材、根據(jù)設(shè)計加工制作，一般制成矩形。消聲器的作用：消聲器是一種既能允許氣流通過，又能有效地阻止或減弱聲能向外傳播的裝置。當噪聲源在室內(nèi)產(chǎn)生的聲壓級高于允許的噪聲標準時，就需要根據(jù)各頻帶要求消除的聲壓級選擇的消聲裝置，消除超出室內(nèi)的噪聲標準范圍的那部分聲能。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。在通風空調(diào)系統(tǒng)中的動力設(shè)備，如新風機等會產(chǎn)生空氣動力噪聲。氣流經(jīng)過風管系統(tǒng)的各個管件、部件時，會產(chǎn)生氣流再生噪聲。當風機的噪聲在經(jīng)過各種自然消減后仍然不能滿足室內(nèi)噪聲標準時，就必須在管路上設(shè)置專門的消聲裝置，并使其在各頻帶的消聲量能基本滿足設(shè)計需要。消聲器用于減小排氣脈動，并盡可能降低排氣噪聲。崇左消聲器多少錢一個</p><p
