主要適用于風(fēng)機(jī)接管口處，因?yàn)轱L(fēng)機(jī)的接管口是圓形的。圓形結(jié)構(gòu)的風(fēng)機(jī)消聲器有兩種不同的類(lèi)型，一種是兩端都是法蘭盤(pán)直接串聯(lián)在一起的(我們稱之為管道消聲器);另外一種就是只有一端是法蘭盤(pán)，另一處是倆呢及大氣排放，把產(chǎn)生的聲音直接排出在外。 </p> <p> 2、矩形結(jié)構(gòu) </p> <p>

微穿孔板式消聲器一般是用厚度小于1mm的純金屬薄板制作，在薄板上用孔徑小于1mm的鉆頭穿孔，穿孔率為1%一5%。選擇不同的穿孔率和板厚不同的腔深，就可以控制消聲器的頻譜性能，使其在需要的頻率范圍內(nèi)獲得良好的消聲效果。 </p> <p> 小孔式小孔消聲器的結(jié)構(gòu)是一根末端封閉的直管，管壁上鉆有很多小孔。小孔消聲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(lái)代替，當(dāng)氣流經(jīng)過(guò)小孔時(shí)、噴氣噪聲的頻譜就會(huì)移向高頻或超高頻，使頻譜中的可聽(tīng)聲成分明顯降低，從而減少對(duì)人的干擾和傷害。 </p> <p> 有源式基本原理是在原來(lái)的聲場(chǎng)中，利用電子設(shè)備再產(chǎn)生一個(gè)與原來(lái)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(lái)的聲場(chǎng)相抵消。這種消聲器是一套儀器裝置，主要由傳聲器、放大器、相移裝置、功率放大器和揚(yáng)聲器等組成。連云港離心風(fēng)機(jī)消音器批發(fā)價(jià)格無(wú)論是應(yīng)用到蒸汽中的，還是在清理鍋爐時(shí)用到的，都在很大程度上降低了噪聲，豐富了大家的生活。</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(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(lèi)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(guò)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(guò)網(wǎng)孔．只能在小室中來(lái)回反射，因此，我們稱這種對(duì)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?？剐韵羝鬟m用于消除中、低頻噪聲。不一樣設(shè)備對(duì)消音器功用的影響一樣一個(gè)消音器,
