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代替，當(dāng)氣流經(jīng)過小孔時(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。有源式消聲器基本原理是在原來的聲場(chǎng)中，利用電子設(shè)備再產(chǎn)生一個(gè)與原來的聲壓大小相等、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。茂名消聲器廠家哪家便宜排氣消聲器的主要是通過減低、衰減排氣壓力的脈動(dòng)來消除噪聲的。</p><div

style="text-indent:25px">盤式消聲器的形狀類似圓盤，具有較小的長度，氣流和聲波通過圓盤四周輻射，適合于在某些情況下，現(xiàn)場(chǎng)條件和空間不容許安裝較長形狀的消聲器。彎頭式消聲器是一種氣流管道彎曲的消聲器，多用于房間里的通風(fēng)空調(diào)進(jìn)風(fēng)、排風(fēng)作用。小室式消聲器優(yōu)點(diǎn)是消聲頻帶較寬，消聲量較大；缺點(diǎn)是阻力損失較大，占用空間也大，一般適用于低速進(jìn)、排風(fēng)消聲。從吸聲原理上講，阻性消聲器對(duì)中、高頻噪聲的消除效果較好；但隨著頻率升高，高頻聲波的方向性越來越好，集束性越來越強(qiáng)，聲波以窄束狀通過消聲器，而與吸聲材料的接觸率有效減少，導(dǎo)致消聲量明顯下降。</p><p style="text-indent:25px">消聲器的安裝應(yīng)注意以下問題：消聲器的接口要牢靠。消聲器往往安裝在設(shè)備或管道上，消聲器與設(shè)備或管道的連接一定要牢靠，重量大的消聲器應(yīng)支撐在專門的承重架上，若管道為支撐架，必須注意支撐的強(qiáng)度和剛度。在消聲器前后加接變徑管。對(duì)于風(fēng)機(jī)消聲器，為減小機(jī)振動(dòng)對(duì)消聲器的影響，消聲器不應(yīng)與風(fēng)機(jī)接口直接連接，而應(yīng)加設(shè)中間管道。一般情況下，該中間管道長度應(yīng)為風(fēng)機(jī)接口直徑的3-4倍。當(dāng)選用的消聲器的接口尺寸與風(fēng)機(jī)接口不同時(shí)，可以在消聲器前后加接變徑管。消聲器接口尺寸應(yīng)大于風(fēng)機(jī)接口尺寸。對(duì)于脈動(dòng)低頻噪聲源、變頻帶噪聲源，宜采用抗性或微穿孔板阻抗復(fù)合式消聲器。</p><div

style="text-indent:25px">消聲器是指對(duì)于同時(shí)具有噪聲傳播的氣流管道，可以用附有吸聲襯里的管道及彎頭或利用截面積突然改變及其他聲阻抗不連續(xù)的管道等降噪器件，使管道內(nèi)噪聲得到衰減或反射回去。前者稱為阻性消聲器，后者稱為抗性消聲器，也有阻抗復(fù)合式的消聲器。種類，消聲器種類很多，但究其消聲機(jī)理，又可以把它分為六種主要的類型，即阻性消聲器、抗性消聲器、阻抗復(fù)合式消聲器、微穿孔板消聲器、小孔消聲器和有源消聲器。結(jié)構(gòu)：根據(jù)汽車底部的空間狀況，消聲器外罩可加工成瓦狀或卷成鍋狀。鍋狀消聲器的外罩是用圓形心棒將外罩材料成型并咬合或用焊接連接整體安裝，并將焊接的部件裝入接口。鍋狀消聲器由內(nèi)管、轉(zhuǎn)向彎管和中間底板組成，之后外部底板通過合槽或焊接與外罩相連。當(dāng)汽車底部空間狀況復(fù)雜，安裝鍋狀消聲器困難時(shí)則可采用深拉伸的瓦狀消聲器。它幾乎可做成任何的形式。轎車消聲器的總?cè)莘e為發(fā)動(dòng)機(jī)排量的8~12倍。消聲器，從它的材料的選擇上面就能知曉其的穩(wěn)定性，使用壽命非常的長久。陽江消聲器制造廠家</p><p style="text-indent:25px">干涉型消聲器適用于消減某保持不變的單一頻率的噪聲。陽江消聲器制造廠家</p><p style="text-indent:25px">阻性消聲器的種類很多，按照氣流通道的幾何形狀可分為通道片式消聲器、通道拆板式消聲器、雙圓筒式消聲器、室式(迷宮式)消聲器、蜂窩狀消聲器、菱形消聲器、正弦波形消聲器及圓筒插管式消聲器。阻性消聲器的消聲原理是利用聲阻進(jìn)行消聲的，也就是說，在推導(dǎo)消聲量的計(jì)算公式時(shí)，**考慮聲阻礙對(duì)消聲的貢獻(xiàn)，而忽略聲抗的影響。在實(shí)際工程中，常常利用吸聲材料來制作阻性消聲器，以達(dá)到降低噪聲的目的。這是由于當(dāng)聲波通過襯貼有多孔吸聲材料的管道時(shí)，聲波將激發(fā)多孔材料中無數(shù)小孔內(nèi)空氣分子的振動(dòng)。其中一部分聲能將用于克服摩擦阻力和粘滯力，而變?yōu)闊崮?。一般的說，阻性消聲器具有良好的中高頻消聲性能，而低頻性能則較差。然而只要適當(dāng)增加吸聲材料的厚度、密度以及選用較低的空隙率，低中頻消聲性能就能有效改善，從而可以做成寬頻帶阻性消聲器。陽江消聲器制造廠家</p><p
