滿足質(zhì)量守恒定律、動量守恒定律和能量守恒定律。在橫流穿孔管消音器中，穿孔周圍會產(chǎn)生較大的漩渦和湍流現(xiàn)象，所以認(rèn)為消音器內(nèi)的氣體流動為湍流流動。根據(jù)排氣消音器的工作條件和阻力損失的定義，在數(shù)值仿真中選取進口為速度入口，出口為壓力出口，并假設(shè)消音器壁面光滑無摩擦，氣體參數(shù)為常數(shù)，忽略氣體重力的影響。本節(jié)應(yīng)用有限體積法，采用湍流計算的模型進行阻力特性分析。</p><p> 小孔消聲器和有源消聲器的設(shè)計原理： </p> <p> 小孔消聲器結(jié)構(gòu)是一根末端封閉的直管，管壁上鉆有很多小孔。小孔消音器的原理是以噴氣噪聲的頻譜為依據(jù)的，如果保持噴口的總面積不變而用很多小噴口來代替，當(dāng)氣流經(jīng)過小孔時、噴氣噪聲的頻譜就會移向高頻或超高頻，使頻譜中的可聽聲成分明顯降低，從而減少對人的干擾和傷害。 </p> <p> 有源消聲器是基本原理是在原來的聲場中，利用電子設(shè)備再產(chǎn)生一個與原來的聲壓大小相等、相位相反的聲波，使其在一定范圍內(nèi)與原來的聲場相抵消。這種消音器是一套儀器裝置，主要由傳聲器、放大器、相移裝置、功率放大器和揚聲器等組成。辦公大廈噪音的低頻源主要包括電梯、變壓器、高層建筑水泵、中央空調(diào)(包括冷卻塔)和交通噪音。</p><div

抗性消聲器由突變界面的管和室組合而成的，好象是一個聲學(xué)濾波器，與電學(xué)濾波器相似，每一個帶管的小室是濾波器的一個網(wǎng)孔，管中的空氣質(zhì)量相當(dāng)于電學(xué)上的電感和電阻，稱為聲質(zhì)量和聲阻。小室中的空氣體積相當(dāng)于電學(xué)上的電容，稱為聲順。與電學(xué)濾波器類似，每一個帶管的小室都有自己的固有頻率。當(dāng)包含有各種頻率成分的聲波進入前列個短管時，只有在前列個網(wǎng)孔固有頻率附近的某些頻率的聲波才能通過網(wǎng)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(wǎng)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(jié)構(gòu)為聲學(xué)濾波器。選取適當(dāng)?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。抗性消音器適用于消除中、低頻噪聲。氣流在消音器內(nèi)發(fā)生一種附加的再生噪聲。連云港除塵風(fēng)機消音器哪個公司便宜</p><p style="text-indent:25px">在工業(yè)中還會使用低壓蒸汽排氣消聲器，普遍的應(yīng)用到各個低壓裝置當(dāng)中。連云港除塵風(fēng)機消音器哪個公司便宜</p><p> 適用于鍋爐等蒸汽設(shè)備的TB型點火排氣消聲器 </p> <p> TB型鍋爐點火排汽消聲器綜合了PB型排汽（氣）消聲器比較合理的消聲原理所設(shè)計。高壓蒸汽在消聲器內(nèi)經(jīng)一次控流后進入降壓體，經(jīng)大容積再次擴容降壓后，往往會因排汽偏離設(shè)計值等諸多原因，使排氣噪聲仍然高于標(biāo)準(zhǔn)值。為此，在降壓體外設(shè)計了組合型多材料復(fù)合結(jié)構(gòu)的阻聲吸音罩，復(fù)合阻聲吸音罩是根據(jù)降壓體所噴出的剩余噪聲的頻譜特性所設(shè)計，用以有效地吸收剩余噪聲。當(dāng)用戶按要求安裝后，總消聲量可達36～42分貝。連云港除塵風(fēng)機消音器哪個公司便宜</p><p
