style="text-indent:25px">盤式消聲器的形狀類似圓盤，具有較小的長(zhǎng)度，氣流和聲波通過圓盤四周輻射，適合于在某些情況下，現(xiàn)場(chǎng)條件和空間不容許安裝較長(zhǎng)形狀的消聲器。彎頭式消聲器是一種氣流管道彎曲的消聲器，多用于房間里的通風(fēng)空調(diào)進(jìn)風(fēng)、排風(fēng)作用。小室式消聲器優(yōu)點(diǎn)是消聲頻帶較寬，消聲量較大；缺點(diǎn)是阻力損失較大，占用空間也大，一般適用于低速進(jìn)、排風(fēng)消聲。從吸聲原理上講，阻性消聲器對(duì)中、高頻噪聲的消除效果較好；但隨著頻率升高，高頻聲波的方向性越來越好，集束性越來越強(qiáng)，聲波以窄束狀通過消聲器，而與吸聲材料的接觸率有效減少，導(dǎo)致消聲量明顯下降。云浮消聲器品牌可使用小孔噴注型消聲器，前提是排放量必需足夠大，不能產(chǎn)生悶壓及節(jié)流，一般為全不銹鋼制造。</p><div

style="text-indent:25px">消聲器是指對(duì)于同時(shí)具有噪聲傳播的氣流管道，可以用附有吸聲襯里的管道及彎頭或利用截面積突然改變及其他聲阻抗不連續(xù)的管道等降噪器件，使管道內(nèi)噪聲得到衰減或反射回去。前者稱為阻性消聲器，后者稱為抗性消聲器，也有阻抗復(fù)合式的消聲器。種類，消聲器種類很多，但究其消聲機(jī)理，又可以把它分為六種主要的類型，即阻性消聲器、抗性消聲器、阻抗復(fù)合式消聲器、微穿孔板消聲器、小孔消聲器和有源消聲器。結(jié)構(gòu)：根據(jù)汽車底部的空間狀況，消聲器外罩可加工成瓦狀或卷成鍋狀。鍋狀消聲器的外罩是用圓形心棒將外罩材料成型并咬合或用焊接連接整體安裝，并將焊接的部件裝入接口。鍋狀消聲器由內(nèi)管、轉(zhuǎn)向彎管和中間底板組成，之后外部底板通過合槽或焊接與外罩相連。當(dāng)汽車底部空間狀況復(fù)雜，安裝鍋狀消聲器困難時(shí)則可采用深拉伸的瓦狀消聲器。它幾乎可做成任何的形式。轎車消聲器的總?cè)莘e為發(fā)動(dòng)機(jī)排量的8~12倍。筒式消聲器一般由排氣管、連接螺套、消聲筒和筒芯等幾部分組成。</p><div

style="text-indent:25px">風(fēng)機(jī)類消聲器選購(gòu)，用戶應(yīng)提交風(fēng)機(jī)類型(分鼓風(fēng)機(jī)、通風(fēng)機(jī)、羅茨風(fēng)機(jī)、軸流風(fēng)機(jī)、空壓機(jī)等)，并提供風(fēng)機(jī)進(jìn)出口尺寸及風(fēng)量，一般風(fēng)機(jī)消聲器都是安裝在出口，風(fēng)機(jī)消聲應(yīng)綜合治理，即消聲器與隔聲室同時(shí)安裝。風(fēng)機(jī)消聲器外殼體為碳鋼，內(nèi)部材質(zhì)分鋁板和不銹鋼兩種，用戶可按成本情況選定。、鍋爐蒸汽排放類消聲器選購(gòu)，用戶應(yīng)提供每小時(shí)的排放量，排汽出口尺寸，排汽溫度及壓力即可。排汽消聲器一般選購(gòu)抗噴阻復(fù)合型消聲器，該消聲器一般外殼體為碳鋼，接管及內(nèi)部材質(zhì)為不銹鋼，具有消聲頻帶寬、使用范圍廣、消聲量大、耐高溫高壓、不怕水汽及油霧等優(yōu)點(diǎn)。也可使用小孔噴注型消聲器，一般為全不銹鋼制造。排氣消聲器的主要是通過減低、衰減排氣壓力的脈動(dòng)來消除噪聲的。云浮消聲器品牌</p><p style="text-indent:25px">對(duì)于低、中頻噪聲源，宜采用共振型消聲器、膨脹型消聲器等抗性消聲器。云浮消聲器品牌</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。云浮消聲器品牌</p><p
