style="text-indent:25px">消聲器是指對于同時(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。來賓消聲器質(zhì)量哪家好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。</p><div

style="text-indent:25px">消聲器適用于各類蒸汽安全閥用的TA型蒸汽安全閥，適用于電站鍋爐安全閥(動(dòng)力釋放閥)、鍋筒安全閥及過熱器安全閥、再熱器安全閥等壓力裝置的安全門。其蒸汽放空既應(yīng)避免過大的噪聲，更應(yīng)讓汽流順利排出而不影響安全閥的排量、起跳和回座，為此，以往常見的多級節(jié)流及小孔噴注的消聲降音手段即不宜采用，這種限制歷來是安全閥消聲器的設(shè)計(jì)難點(diǎn)，也是安全門消聲器消聲效果差的原因。新型用于安全閥的TA型安全閥排汽消聲器采用了噴阻抗復(fù)合型消聲原理，其中以大孔擴(kuò)容代替了直徑較小的控流孔，在結(jié)構(gòu)上更加強(qiáng)化了抗性和阻性消聲降音機(jī)理，達(dá)到了安全系數(shù)更高的消聲降噪效果。</p><p style="text-indent:25px">共振腔消聲器。共振腔消聲器消聲原理是利用聲波頻率與共振腔固有頻率一致時(shí)對聲能的衰減達(dá)到較大進(jìn)行消聲。與擴(kuò)張室消聲器相比，共振腔消聲器具有消聲頻帶較窄，在共振頻率附近消聲量較大的特點(diǎn)，適用于具有單峰值頻率、且峰值較突出的高噪聲場合。設(shè)計(jì)時(shí)要求共振腔消聲器的共振頻率與聲波的主頻率一致。干涉型消聲器。干涉型消聲器是利用支管長度比主管長度長，并且多出的長度正好是1/2聲波波長的奇數(shù)倍，這樣支管聲波與主管聲波在振幅上相等，而在相位上相差180°的奇數(shù)倍，從而達(dá)到相互干涉而抵消，來實(shí)現(xiàn)消聲的目的。干涉型消聲器適用于消減某保持不變的單一頻率的噪聲，對于寬頻帶噪聲，這種型式消聲器無效。??對中、高頻噪聲源，宜采用阻性或復(fù)合型消聲器。</p><div

style="text-indent:25px">風(fēng)機(jī)設(shè)計(jì)和選用的消聲器應(yīng)考慮下列問題：根據(jù)風(fēng)機(jī)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(shè)計(jì)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(biāo)準(zhǔn)，要根據(jù)環(huán)境區(qū)域和等級，參考有關(guān)國家或部頒標(biāo)準(zhǔn)。風(fēng)機(jī)噪聲有關(guān)數(shù)據(jù)可由廠家提供，如資料不全，可進(jìn)行估算，要進(jìn)行實(shí)際測量，以便獲得準(zhǔn)確可靠的數(shù)據(jù)，取得較好的噪聲控制效果。設(shè)計(jì)和選用消聲器應(yīng)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(gè)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(fēng)機(jī)消聲器的氣流速度應(yīng)控制在10-20m/s；消聲器宜安裝在風(fēng)機(jī)進(jìn)、出口，即離噪聲源較近，以防風(fēng)機(jī)噪聲激發(fā)管路振動(dòng)；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(gè)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。來賓消聲器質(zhì)量哪家好</p><p
