綜合管架低壓，次中壓蒸汽管道疏水消聲器，消音器主要用于電力、化工、冶金等行業(yè)中安全閥、PCV閥和排汽閥的高溫高壓蒸汽排放的有效消聲。 </p> <p> 對于鍋爐安全閥和排汽閥，它可以看著是管道的一個組成部分，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），相應(yīng)地響度降低60%以上，主觀感覺有明顯效果。設(shè)計安全閥排汽消音器，應(yīng)考慮以下三個方面： </p> <p> 1、消聲后應(yīng)避免過大的噪聲，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，讓蒸汽聲波進入多孔吸聲材料中的無數(shù)小孔內(nèi)，激發(fā)多孔材料分子震動，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。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

阻性消聲器具有吸收中高頻聲等特點，一般用于鼓風(fēng)機、羅茨風(fēng)機、軸流風(fēng)機、離心風(fēng)機、高壓風(fēng)機、空調(diào)風(fēng)機、壓縮機、燃?xì)廨啓C、等風(fēng)機類消聲降噪?？剐韵暺骶邆溽槍π詮?，對中低頻吸聲效果明顯，且不用吸聲材料等特點。一般只能用于小管道排氣消聲，如汽車、柴油機等排氣消聲降噪。阻抗型消聲器具有消聲頻帶寬、使用于安全等特點。主要用于聲級高、但頻率為低中頻寬帶噪音的消聲。如汽輪機、除氧器、擴容器、小排量的安全閥排汽等蒸汽設(shè)備消聲降噪。小孔型消聲器具有低中頻寬帶消聲性能，小的孔徑能提高吸聲系數(shù)，低的孔隙率能增加吸聲頻帶的寬度，孔板深度能改變共振吸聲峰的位置。小孔型消聲器具備設(shè)計嚴(yán)密、吸收頻帶寬、阻損小、耐高溫、壽命長等優(yōu)點。一般用于鍋爐、壓縮機等高壓設(shè)備的排氣放空消聲降噪?？箛娮鑿?fù)合型消聲器具有消聲頻帶寬、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。是建立在中國出名聲學(xué)家馬大猷的小孔噴注消聲理論的基礎(chǔ)上研制成功，也是中國前沿型結(jié)構(gòu)排氣消聲器，各工礦企業(yè)、電廠、化工一般都選擇使用。有源消聲器具有排氣暢、耐高溫、抗干擾強等優(yōu)點。用于各類閥、排氣閥、汽輪機及吹管等排氣消聲降噪。風(fēng)機消聲器在使用的時候要注意不能使其暴露在露天的環(huán)境當(dāng)中，如果安裝在室外的，比較好加裝一個防雨棚才行。連云港消音器多少錢</p><p style="text-indent:25px">無論是應(yīng)用到蒸汽中的，還是在清理鍋爐時用到的，都在很大程度上降低了噪聲，豐富了大家的生活。連云港除塵風(fēng)機消音器批發(fā)價格</p><p> 目前市場上消聲器的種類有很多，客戶可以根據(jù)不同需求進行選擇，消聲器的選擇需要有防火、防潮等特點。消音器的主要工作特點是什么？消音器是中、高頻消聲特征好，加工制造簡單，其中抗性消聲器是通過管道系統(tǒng)反射聲波實現(xiàn)消聲。 </p> <p> 安裝消音器是通過微穿孔板吸聲結(jié)構(gòu)實現(xiàn)消聲，整體設(shè)計合理，這種消聲器可以實現(xiàn)寬頻帶消聲和較低的阻損。擴散消音器也是寬頻帶消聲，另外還有噴霧消聲器、有源消聲器等，消聲器的種類不同可以用于不同的場合。 </p> <p> 風(fēng)機噪音主要是由設(shè)備材質(zhì)、馬達(dá)震動完成的，因為風(fēng)機在工作過程中產(chǎn)生的噪音較大，所以必須要安裝消音器，這是治理風(fēng)機噪音的比較好方式。其中消音器在市場上越來越受歡迎，得到廣大客戶的一致推崇和認(rèn)可。 </p> <p> <br /> </p> <p> 因為風(fēng)機的使用范圍比較普遍，所以消音器可以用于電力、礦山、機械、冶金等行業(yè)，使用它可以降低風(fēng)機產(chǎn)生的噪聲。安裝消音器之后可以治理噪音污染，所以目前市場需求較多，風(fēng)機消音器采用優(yōu)異材料制作而成，所以使用壽命較長。連云港除塵風(fēng)機消音器批發(fā)價格</p><p
