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行消聲的，也就是說，在推導(dǎo)消聲量的計算公式時，**考慮聲阻礙對消聲的貢獻，而忽略聲抗的影響。在實際工程中，常常利用吸聲材料來制作阻性消聲器，以達到降低噪聲的目的。這是由于當(dāng)聲波通過襯貼有多孔吸聲材料的管道時，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。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。蒸汽消聲器可滿足各種參數(shù)鍋爐向空排汽、安全閥排汽及鍋爐送風(fēng)機進口的降噪消聲要求。肇慶消聲器供應(yīng)</p><p
