style="text-indent:25px">消聲器適用于鍋爐等蒸汽設備的TB型點火排氣，TB型鍋爐點火排汽消聲器綜合了PB型排汽（氣）消聲器較合理的消聲原理所設計。高壓蒸汽在消聲器內(nèi)經(jīng)一次控流后進入降壓體，經(jīng)大容積再次擴容降壓后，往往會因排汽偏離設計值等諸多原因，使排氣噪聲仍然高于標準值。為此，在降壓體外設計了組合型多材料復合結(jié)構(gòu)的阻聲吸音罩，復合阻聲吸音罩是根據(jù)降壓體所噴出的剩余噪聲的頻譜特性所設計，用以有效地吸收剩余噪聲。當用戶按要求安裝后，總消聲量可達36～42分貝。珠海消聲器工廠消聲器單獨固定，能滿足管道熱位移的要求。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="珠海消聲器工廠,消聲器"

style="text-indent:25px">阻性式消聲器：主要是利用多孔吸聲材料來降低噪聲的。把吸聲材料固定在氣流通道的內(nèi)壁上或按照一定方式在管道中排列，就構(gòu)成了阻性消聲器。當聲波進入阻性消聲器時，一部分聲能在多孔材料的孔隙中摩擦而轉(zhuǎn)化成熱能耗散掉，使通過消聲器的聲波減弱。阻性消聲器就好象電學上的純電阻電路，吸聲材料類似于電阻。因此，人們就把這種消聲器稱為阻性消聲器。阻性消聲器對中高頻消聲效果好、對低頻消聲效果較差。把阻性結(jié)構(gòu)和抗性結(jié)構(gòu)按照一定的方式組合起來，就構(gòu)成了阻抗復合式消聲器。</p><p style="text-indent:25px">風機設計和選用的消聲器應考慮下列問題：根據(jù)風機噪聲頻譜特性與區(qū)域環(huán)境的允許噪聲頻率特性的差值，決定設計或選用消聲器的消聲頻率特性，即噪聲頻帶的衰減量。噪聲控制標準，要根據(jù)環(huán)境區(qū)域和等級，參考有關(guān)國家或部頒標準。風機噪聲有關(guān)數(shù)據(jù)可由廠家提供，如資料不全，可進行估算，要進行實際測量，以便獲得準確可靠的數(shù)據(jù)，取得較好的噪聲控制效果。設計和選用消聲器應特別注意其阻力損失，如果消聲器的消聲量滿足消聲要求，阻力損失很大，那么該消聲器就不是一個好的消聲器。其次，要避免消聲器的氣流消聲過大，工業(yè)用風機消聲器的氣流速度應控制在10-20m/s；消聲器宜安裝在風機進、出口，即離噪聲源較近，以防風機噪聲激發(fā)管路振動；如消聲器裝在管路中，則氣流是穩(wěn)定的，消聲效果會好；對于降噪要求較高，需要裝幾個消聲器，消聲器宜分段安裝。另外，還要考慮消聲器的使用環(huán)境，如防水、防塵、防霉等，否則，會影響消聲器的消聲性能。消聲器主要由消聲筒、消聲片、上下封板（或封頭）、支座、起吊環(huán)、銘牌等零部件組成。</p><div

style="text-indent:25px">阻抗聲流型通風、排氣管道及風機消聲器結(jié)構(gòu)原理：根據(jù)對工業(yè)用各類風機運行現(xiàn)場噪聲源進行實際測試所取得的頻譜特性資料來確定在哪些頻譜范圍內(nèi)需要多大消聲量作為設計吸聲體及流體通道的主要依據(jù)，同時采用了具有較大吸聲材料飾面的狹矩形通道，以增強吸收效果。另，風機的噪聲源在較大噪聲級時，其頻譜值往往不止一種，而對不同頻譜帶，對其消聲量要求也不相同。為此系列通風管道消音器及鼓引風機消聲器均為阻抗聲流型，采用了對高、中頻噪聲起吸音消聲作用的阻式結(jié)構(gòu)及對中、低頻噪聲起消聲降音作用的抗式結(jié)構(gòu)，同時在阻式通道中采用了高頻及低頻兩種吸音消聲區(qū)，用以較大限度的增寬消聲頻帶，以實現(xiàn)良好的消聲降噪效果。根據(jù)風機噪聲頻譜特性與區(qū)域環(huán)境的允許噪聲頻率特性的差值，決定設計或選用消聲器的消聲頻率特性。珠海消聲器工廠</p><p style="text-indent:25px">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。珠海消聲器工廠</p><p style="text-indent:25px">消聲器是指對于同時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，也有阻抗復合式的消聲器。種類，消聲器種類很多，但究其消聲機理，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。當汽車底部空間狀況復雜，安裝鍋狀消聲器困難時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)動機排量的8~12倍。珠海消聲器工廠</p><p
