南岸推薦消防風機廠家

消聲器是利用聲的吸收、反射、干涉等原理，降低通風與空調系統中氣流噪聲的裝置。南岸消防風機根據消聲原理的不同可以分為阻性、抗性、共振型和復合型等。一、阻性消聲器,阻性消聲器利用吸聲材料的吸聲作用而消聲的。其構造是把吸聲材料固定在氣流流動的管道內壁，推薦消防風機或按(an)一(yi)定方式排列在(zai)管道或殼(ke)體內構(gou)成阻(zu)(zu)性(xing)(xing)消聲(sheng)器，吸聲(sheng)材料(liao)能夠(gou)把入射(she)在(zai)其上的(de)聲(sheng)能部分(fen)地(di)吸收掉。聲(sheng)能之所以能被吸收，是由于(yu)吸聲(sheng)材料(liao)的(de)多孔性(xing)(xing)和松(song)散性(xing)(xing)。當(dang)聲(sheng)波進入孔隙，引起孔隙中的(de)空(kong)氣和材料(liao)產生微小的(de)振動，由于(yu)摩(mo)擦和粘滯阻(zu)(zu)力。使(shi)相當(dang)一(yi)部分(fen)聲(sheng)能化為熱能而被吸收掉。
