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，佛山消聲器工廠，佛山消聲器工廠，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)入個(gè)短管時(shí)，只有在個(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，佛山消聲器工廠，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暺鬟m用于消除中、低頻噪聲。安全閥消聲器排汽消聲器可達(dá)25分貝以上。佛山消聲器工廠</p><div

style="text-indent:25px">風(fēng)機(jī)類消聲器選購(gòu)，用戶應(yīng)提交風(fēng)機(jī)類型(分鼓風(fēng)機(jī)、通風(fēng)機(jī)、羅茨風(fēng)機(jī)、軸流風(fēng)機(jī)、空壓機(jī)等)，并提供風(fēng)機(jī)進(jìn)出口尺寸及風(fēng)量，一般風(fēng)機(jī)消聲器都是安裝在出口，風(fēng)機(jī)消聲應(yīng)綜合治理，即消聲器與隔聲室同時(shí)安裝。風(fēng)機(jī)消聲器外殼體為碳鋼，內(nèi)部材質(zhì)分鋁板和不銹鋼兩種，用戶可按成本情況選定。、鍋爐蒸汽排放類消聲器選購(gòu)，用戶應(yīng)提供每小時(shí)的排放量，排汽出口尺寸，排汽溫度及壓力即可。排汽消聲器一般選購(gòu)抗噴阻復(fù)合型消聲器，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，具有消聲頻帶寬、使用范圍廣、消聲量大、耐高溫高壓、不怕水汽及油霧等優(yōu)點(diǎn)。也可使用小孔噴注型消聲器，一般為全不銹鋼制造。佛山消聲器工廠對(duì)中、高頻噪聲源，宜采用阻性或復(fù)合型消聲器。</p><div

style="text-indent:25px">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。小孔式消聲器，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。有源式消聲器基本原理是在原來(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。</p><p style="text-indent:25px">一般采用靜態(tài)消聲量來(lái)表示消聲器的消聲效果，因?yàn)殪o態(tài)消聲量是一個(gè)定值，而動(dòng)態(tài)消聲量受氣流速度的影響，是一個(gè)不定值，故評(píng)價(jià)指標(biāo)以用靜態(tài)消聲量為宜。當(dāng)聲源經(jīng)靜態(tài)消聲后的剩余聲級(jí)（簡(jiǎn)稱靜態(tài)出口聲級(jí)）大于消聲器氣流噪聲級(jí)時(shí)，消聲器的動(dòng)態(tài)、靜態(tài)消聲量基本一致，不受氣流的影響；當(dāng)消聲器靜態(tài)出口聲級(jí)低于消聲器氣流噪聲級(jí)時(shí)，則消聲器的動(dòng)態(tài)消聲量低于靜態(tài)消聲量，其差值隨流速的增加而增大；當(dāng)氣流噪聲級(jí)大于消聲器入口聲級(jí)時(shí)，此時(shí)消聲器不*不能消聲，反而變成了一個(gè)噪聲放大器。為解決靜態(tài)和動(dòng)態(tài)消聲量可能不一致的問(wèn)題，有些消聲器產(chǎn)品已采用靜態(tài)消聲量和氣流噪聲級(jí)兩個(gè)指標(biāo)同時(shí)表示產(chǎn)品的聲學(xué)性能。消聲器單獨(dú)固定，能滿足管道熱位移的要求。</p><div

style="text-indent:25px">摩托車(chē)消聲器的定期維護(hù):由于發(fā)動(dòng)機(jī)在工作時(shí)，燃油并不是基本可以完全燃燒。加之燃油中還含有一定的雜質(zhì)，因此當(dāng)發(fā)動(dòng)機(jī)排出的高溫廢氣經(jīng)過(guò)排氣消聲器時(shí)，就會(huì)在消聲器的筒芯和隔板上產(chǎn)生積炭，久而久之，堆積起來(lái)的積炭就會(huì)堵塞氣流的通道，使得排氣阻力增大、消聲性能降低、發(fā)動(dòng)機(jī)無(wú)力，影響車(chē)輛正常行駛。嚴(yán)重時(shí)會(huì)導(dǎo)致排氣管變藍(lán)，發(fā)動(dòng)機(jī)溫度過(guò)高而損壞。因此，定期對(duì)摩托車(chē)消聲器進(jìn)行維修清洗是十分必要的。正常情況下，每行駛3000公里左右，應(yīng)將消聲筒和筒芯上的積炭去除干凈;每行駛6000公里應(yīng)將排氣管和消聲器全部拆下來(lái)，將氣缸排氣口及排氣管、消聲器內(nèi)的積炭去除干凈。佛山消聲器工廠</p><p
