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。連云港消音器報(bào)價(jià)如果工業(yè)鍋爐在長(zhǎng)期的使用當(dāng)中，會(huì)產(chǎn)生一些灰塵，需要清理。</p><div

微穿孔板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%一3%。選擇不同的穿孔率和板厚不同的腔深，就可以控制消音器的頻譜性能，使其在需要的頻率范圍內(nèi)獲得良好的消音效果。 </p><p> 工業(yè)消聲器的設(shè)計(jì)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(lái)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(shí)，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(guò)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(duì)中高頻消聲效果好、對(duì)低頻消聲效果較差。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(shuō)是目前比較為先進(jìn)的消聲設(shè)備了。</p><div

style="text-indent:25px">鍋爐點(diǎn)火排汽消聲器（TB）型為控制高壓汽流排放噪聲，當(dāng)前世界上已具有多種形式的的消聲器，其原理大多采用多級(jí)節(jié)流降壓，由于其結(jié)構(gòu)復(fù)雜、重量大、難以解體檢修，因而限制了其應(yīng)用范圍。本新型結(jié)構(gòu)的消聲器克服了上述缺點(diǎn)。本型排汽消聲器系綜合了比較合理的消聲原理所設(shè)計(jì)。高壓蒸汽在排汽消聲器內(nèi)經(jīng)一次控流后進(jìn)入降壓體經(jīng)大容積擴(kuò)壓后，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是設(shè)計(jì)，用以有效地吸收剩余噪聲。當(dāng)用戶按要求安裝后，總噪聲量要達(dá)36～42分貝。并汽母管排氣消聲器，主蒸汽管道排氣消聲器，消音器主要用于電力、化工、冶金等工作中。連云港除塵風(fēng)機(jī)消音器銷售</p><p

對(duì)于鍋爐安全閥和排汽閥，它可以看著是管道的一個(gè)組成部分，在內(nèi)部作聲學(xué)處理后，可減弱噪音的產(chǎn)生與傳播，使出口噪聲消聲量達(dá)到20∽30分貝（A聲級(jí)），相應(yīng)地響度降低60%以上，主觀感覺(jué)有明顯效果。設(shè)計(jì)安全閥排汽消音器，應(yīng)考慮以下三個(gè)方面： </p> <p> 1、消聲后應(yīng)避免過(guò)大的噪聲，消聲量能滿足《工業(yè)企業(yè)噪聲衛(wèi)生標(biāo)準(zhǔn)》的要求。 </p> <p> 2、消音器防銹、防堵、耐高溫、高壓、高氣流。 </p> <p> 3、消音器的排放量與阻塞比應(yīng)適應(yīng)安全閥排汽氣流順利排除。 </p> <p> 二、綜合管架低壓，次中壓蒸汽管道疏水消聲器，消音器原理 </p> <p> 新型安全門消音器采用了通孔噴、阻的消聲原理，其中以大孔擴(kuò)容控流代替微孔穿板型，在結(jié)構(gòu)上首先保證安全門排汽必須順暢的原理，多層次穿孔吸聲，并結(jié)合了阻性消聲原理，讓蒸汽聲波進(jìn)入多孔吸聲材料中的無(wú)數(shù)小孔內(nèi)，激發(fā)多孔材料分子震動(dòng)，使聲能為了克服摩擦阻力和粘滯力而變成熱能，即達(dá)到了理想的消聲效果，更保證了蒸汽順利排除。連云港消音器安裝</p><p
