style="text-indent:25px">抗性消聲器可以分為5種基本形式：擴(kuò)張室消聲器、共鳴型消聲器、干涉型消聲器、損耗型消聲器和文氏型消聲器。消聲原理：擴(kuò)張室消聲器一是利用管道的裁面突變，即聲阻抗的變化使沿管道傳播的聲波向聲源方向反射回去；二是利用擴(kuò)張室和內(nèi)插管的長(zhǎng)度，使向前傳播的波和管子不同界面反射的聲波差一個(gè)180度的相位、從而使二者振幅相等、相位相反，互相干涉，達(dá)到較理想的消聲效果。共鳴型消聲器常用于消除管道傳播的低頻(350Hz以下)噪聲。干涉型消聲器的消聲原理足將聲波分成兩路，在管道上裝設(shè)一排通管，使管道長(zhǎng)度為通管長(zhǎng)度的2倍。管道長(zhǎng)度等于要消除的聲波的波長(zhǎng)，那么通管的長(zhǎng)度則為二分之一波長(zhǎng)。這樣聲波當(dāng)通過(guò)兩種不同長(zhǎng)度的途徑時(shí)，在管道與通管匯合處將產(chǎn)生振幅相等，位移相反的2種聲波，彼此互相干涉，從而降低噪聲。南寧消聲器批發(fā)多少錢消聲器等消聲設(shè)備安裝，須有**的承重吊桿或底座與聲源設(shè)備須通過(guò)軟接頭連接。</p><div
