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(jìn)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(dá)第二個短管口，連云港除塵風(fēng)機(jī)消音器，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(jìn)行組合，就可以濾掉某些頻率成分的噪聲，從而達(dá)到消聲的目的。抗性消音器適用于消除中、低頻噪聲，連云港除塵風(fēng)機(jī)消音器。按照標(biāo)準(zhǔn)工作日工作時間，連云港除塵風(fēng)機(jī)消音器，頂多噪音值不高于85分貝，工作時間越長要求越高。連云港除塵風(fēng)機(jī)消音器</p><div

空氣管道消音器是主要建立在“小孔噴注”理論結(jié)合阻抗擴(kuò)容吸聲的消音原理，鍋爐蒸汽排放一般流速快，氣流噪聲高，需先以通孔擴(kuò)流，經(jīng)過多次通孔后的蒸汽在抗性擴(kuò)張室得到降壓降流，氣流再經(jīng)小孔噴出，噴出后其各倍頻帶的聲功率已降低，而聲壓級的頻率被推高到20000Hz以上范圍，其噪聲大為削弱，但部分頻率的二次噪音還需要進(jìn)一步消音，我們在擴(kuò)張室外加裝阻性吸聲棉結(jié)構(gòu)，它系根據(jù) 降壓體所發(fā)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，消音量可達(dá)30-42分貝。使之達(dá)到工業(yè)企業(yè)噪聲標(biāo)準(zhǔn)要求。 </p> <p> 空氣管道消音器也是一種利用渦流消音原理的消音器，與馬克沁消音器的區(qū)別是將膜片換成螺旋片，螺旋片中心開有彈頭通道。 </p> <p> 吸熱消音原理 </p> <p> 在空氣管道消音器內(nèi)裝有吸聲或吸熱材料，當(dāng)伙藥燃?xì)馔ㄟ^時，部分能量被這些材料吸收，使伙藥燃?xì)饫鋮s、減壓，從而降低搶口噪聲。吸熱體多采用銅、鋁等導(dǎo)熱性能好的材料，有的用金屬網(wǎng)纏繞或利用金屬絲、金屬屑壓成一定的密度和形狀。由于吸熱材料的溫度上升很快，故吸熱消音原理的消音器用于單發(fā)射擊消音效果很好，而用于連發(fā)射擊時消音效果不理想。連云港蜂窩式風(fēng)機(jī)蒸汽消音器批發(fā)低頻噪音指頻率低于500赫茲(八度)的聲音。</p><div

暖通空調(diào)施工過程中，專業(yè)的安裝是不可短少的，是確保產(chǎn)品運(yùn)行順暢、確保杰出室內(nèi)環(huán)境的要害。消聲器，在下降暖通空調(diào)運(yùn)行噪音中，有著不小的效果，其挑選不能忽視?，F(xiàn)今，我們一起來簡略了解一下小消聲器的作業(yè)原理 </p> <p> <br /> </p> <p> 暖通空調(diào)消聲器作業(yè)原理： </p> <p> <br /> </p> <p> 消聲器的種類頗多，包含有阻性、抗性、共振型、復(fù)合型等，是運(yùn)用聲的吸收、干與、反審核等原理，下降體系中存在的氣流噪音。在暖通空調(diào)的降噪過程中，消聲器的效果不容小覷。 </p> <p> 將風(fēng)管構(gòu)件進(jìn)行恰當(dāng)?shù)奶幚?，也能起到消除噪音的效果，包含有消聲彎頭、消聲靜壓箱等等。想要真正確保暖通空調(diào)的運(yùn)行順暢，做好降噪作業(yè)，專業(yè)暖通公司的支持才是要害。 </p> <p> <br /> </p> <p> </p><p> 工業(yè)消聲器的設(shè)計原理： </p> <p> 阻性消聲器； </p> <p> 阻性消聲器主要是利用多孔吸聲材料來降低噪聲的。把吸聲材料固定在氣流通道的內(nèi)壁上或按照一定方式在管道中排列，就構(gòu)成了阻性消音器。當(dāng)聲波進(jìn)入阻性消音器時，一部分聲能在多孔材料的孔隙中摩擦而轉(zhuǎn)化成熱能耗散掉，使通過消音器的聲波減弱。阻性消音器就好象電學(xué)上的純電阻電路，吸聲材料類似于電阻。因此，人們就把這種消音器稱為阻性消音器。阻性消音器對中高頻消聲效果好、對低頻消聲效果較差。低頻噪音下降緩慢，聲波較長，所以它可以很容易地通過障礙。</p><div

本型復(fù)式消聲器系綜合了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(jìn)入降壓體經(jīng)大容積擴(kuò)壓后，從而形成低壓蒸汽后噴出，在此過程中，汽流內(nèi)能部分轉(zhuǎn)化成某種頻率的聲能，其噪聲雖然功率大為削弱，但往往會因排汽偏離設(shè)計值等諸原因，使噪聲仍然高于標(biāo)準(zhǔn)值。為此，在降壓體外設(shè)計了一只雙層結(jié)構(gòu)的阻聲罩，它系根據(jù)降壓體所發(fā)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(dá)36～45分貝。 </p> <p> 復(fù)合型消聲器，適用于450度以內(nèi)，6.4Mpa以內(nèi) </p> <p> TA型蒸汽排汽消聲器，TA指帶阻聲罩消聲器（復(fù)合式），在小孔型的基礎(chǔ)上增加了阻聲罩，有消音棉填料，氣體從底部接管進(jìn)入，從上部排出。由于有消音棉填料，適合于壓力在6.4Mpa以內(nèi)，否者填料被吹出，殼體是碳鋼適用于450度以內(nèi)。排氣消聲器的類型基本上有兩種，分為PX樣例小孔消聲器和TA-樣例帶阻聲罩消聲器。連云港蜂窩式風(fēng)機(jī)蒸汽消音器批發(fā)</p><p
