沙坪壩推薦廚房排煙管道批發

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。沙坪壩廚房排煙管道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，推薦廚房排煙管道或按(an)一(yi)定方式排列(lie)在管道或殼體內構成阻(zu)(zu)性消聲器，吸(xi)聲材料(liao)能(neng)(neng)夠把入射在其(qi)上(shang)的(de)聲能(neng)(neng)部分(fen)地(di)吸(xi)收(shou)(shou)掉。聲能(neng)(neng)之(zhi)所以能(neng)(neng)被(bei)(bei)吸(xi)收(shou)(shou)，是由于吸(xi)聲材料(liao)的(de)多孔(kong)性和松散性。當聲波(bo)進入孔(kong)隙(xi)，引起孔(kong)隙(xi)中(zhong)的(de)空氣和材料(liao)產(chan)生微小的(de)振動，由于摩擦(ca)和粘滯(zhi)阻(zu)(zu)力(li)。使相當一(yi)部分(fen)聲能(neng)(neng)化為熱能(neng)(neng)而被(bei)(bei)吸(xi)收(shou)(shou)掉。
