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(gè)聲學(xué)濾波器，與電學(xué)濾波器相似，每一個(gè)帶管的小室是濾波器的一個(gè)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(gè)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(gè)短管時(shí)，只有在前列個(gè)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(gè)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(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。抗性消聲器適用于消除中、低頻噪聲。把阻性結(jié)構(gòu)和抗性結(jié)構(gòu)按照一定的方式組合起來，就構(gòu)成了阻抗復(fù)合式消聲器。</p><p> 阻抗聲流型通風(fēng)、排氣管道及風(fēng)機(jī)消聲器結(jié)構(gòu)原理根據(jù)對工業(yè)用各類風(fēng)機(jī)運(yùn)行現(xiàn)場噪聲源進(jìn)行實(shí)際測試所取得的頻譜特性資料來確定在哪些頻譜范圍內(nèi)需要多大消聲量作為設(shè)計(jì)吸聲體及流體通道的主要依據(jù)，同時(shí)采用了具有較大吸聲材料飾面的狹矩形通道，以增強(qiáng)吸收效果。另，風(fēng)機(jī)的噪聲源在比較大噪聲級時(shí)，其頻譜值往往不止一種，而對不同頻譜帶，對其消聲量要求也不相同。為此系列通風(fēng)管道消音器及鼓引風(fēng)機(jī)消聲器均為阻抗聲流型，采用了對高、中頻噪聲起吸音消聲作用的阻式結(jié)構(gòu)及對中、低頻噪聲起消聲降音作用的抗式結(jié)構(gòu)，同時(shí)在阻式通道中采用了高頻及低頻兩種吸音消聲區(qū)，用以比較大限度的增寬消聲頻帶，以實(shí)現(xiàn)良好的消聲降噪效果。 </p> <p> <br /> 風(fēng)機(jī)消聲器是一種專業(yè)的消聲設(shè)備，它降噪的效果是非常突出的，可以說是目前比較為先進(jìn)的消聲設(shè)備了。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

每個(gè)企業(yè)所需要的消聲器是不同的是要根據(jù)自己所需的配套實(shí)施來計(jì)算所需的消聲器大小，消聲器的發(fā)明創(chuàng)造是通過必定的數(shù)據(jù)驗(yàn)算，而且不計(jì)其數(shù)的試驗(yàn)終究得來的，而且不同的場合使用的消聲器也是不同的，在這樣的基礎(chǔ)上應(yīng)該清晰的就是消聲器核算的過程中存在著壓力丟失，現(xiàn)在我們就來看下壓力丟失是怎么進(jìn)行核算的。 </p> <p> 風(fēng)機(jī)消聲器的壓力丟失包含兩個(gè)方面，也就是消聲器內(nèi)通道壁面和氣流矛盾所發(fā)生的矛盾壓力丟失，別的一種就是消聲器內(nèi)部架構(gòu)通道拐折、截面變化等導(dǎo)致氣流活動(dòng)狀況改變所發(fā)生的部分壓力丟失。 </p> <p> 在消聲器使用的過程中前面的部分丟失仍是占有主導(dǎo)地位的，導(dǎo)流管對部分丟失補(bǔ)償仍是很大的，這個(gè)時(shí)分核算能量損耗的話就是通過前后導(dǎo)流管出流的速度進(jìn)行比較的，也就是兩者之間的差值越大的話，樣例著壓力丟失也越大。 </p> <p> 在核算消聲器的壓力丟失的時(shí)分，其間不能忽視的一個(gè)概念就是消聲量，也就是風(fēng)機(jī)消聲器在聲學(xué)課程中是重要的目標(biāo)，一般采用的都是刺進(jìn)丟失進(jìn)行比較的，也就是在消聲器的前后、左右都進(jìn)行的聲源共同的時(shí)分進(jìn)行檢測，這個(gè)時(shí)分滿意的就是距離統(tǒng)一、方向共同、聲學(xué)環(huán)境也一樣的情況下檢測聲級之間的差值。不一樣設(shè)備對消音器功用的影響一樣一個(gè)消音器, 設(shè)備方位不一樣, 降噪效果不一樣。連云港離心風(fēng)機(jī)消音器價(jià)格</p><p style="text-indent:25px">除風(fēng)機(jī)本身的固定噪音外，尚有許多噪音源，諸如：軸承因精密度不足，裝配不當(dāng)或維護(hù)不佳會(huì)造成異常噪音。連云港消音器哪家價(jià)格優(yōu)惠</p><p> 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(jì)。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(huì)因排汽偏離設(shè)計(jì)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(jì)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(jì)，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)。連云港消音器哪家價(jià)格優(yōu)惠</p><p
