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。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(jī)進(jìn)口的降噪消聲要求。茂名消聲器價(jià)錢</p><p

style="text-indent:25px">迷宮式消聲器是在直管消聲器基礎(chǔ)上，插入一些吸聲障板，使聲波不斷的由一個(gè)小室繞行到另一個(gè)小室，從而增加了消聲效果，特別在中低頻率范圍，當(dāng)然阻力也要增加。迷宮式消聲器中的氣流速度不宜太高。蜂窩式消聲器的結(jié)構(gòu)特點(diǎn)類似于片式消聲器，只是為了進(jìn)一步減小每一個(gè)消聲器通道截面尺寸，把整個(gè)大的通道分成多個(gè)蜂窩式小的消聲通道。聲流式消聲器類似于折板式消聲器，只是為了減小阻力，把通道加工成聲流式。聲流式消聲器阻力較低，但是結(jié)構(gòu)較為復(fù)雜，加工難度較大。茂名消聲器價(jià)錢</p><p
