style="text-indent:25px">盤式消聲器的形狀類似圓盤，具有較小的長度，氣流和聲波通過圓盤四周輻射，適合于在某些情況下，現(xiàn)場條件和空間不容許安裝較長形狀的消聲器。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空調(diào)進風、排風作用。小室式消聲器優(yōu)點是消聲頻帶較寬，消聲量較大；缺點是阻力損失較大，占用空間也大，一般適用于低速進、排風消聲，梧州消聲器供應公司。從吸聲原理上講，梧州消聲器供應公司，阻性消聲器對中，梧州消聲器供應公司、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，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，導致消聲量明顯下降。微穿孔消聲器耐高溫、耐高速氣流沖擊。梧州消聲器供應公司</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="梧州消聲器供應公司,消聲器"

style="text-indent:25px">消聲器的原理：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。在連接螺套里裝有油浸石棉密封圈，以防止排氣管和消聲筒之間的接口漏氣。消聲筒內(nèi)焊有7塊隔板，將消聲筒分成8個消聲腔（七個膨脹室和一個共振腔）在筒芯上面有倒三角形導流槽和許多小孔，當發(fā)動機的高溫廢氣以高速經(jīng)排氣管進入消聲器時，由于消聲筒的截面積逐漸增大，氣流得以膨脹，流速降低，強大的脈動噪聲得以衰減。當氣流繼續(xù)流經(jīng)各膨脹室時，由于隔板的阻擋，氣流只能從隔板上的節(jié)流了、及筒芯通過，于是氣流突然被壓縮，分成許多細流，后又突然得以膨脹，如此多次突變，聲能被有效衰減，從而起到降低排氣噪聲的作用。梧州消聲器供應公司蒸汽消聲器體積小，重量輕，安裝簡便，易維護。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="梧州消聲器供應公司,消聲器"

style="text-indent:25px">消音器的改裝管按材料來分可以分為鋁合金摩托車排氣管，不銹鋼摩托車排氣管，碳纖維摩托車排氣管，鈦合金摩托車排氣管等等，各有千秋。鋁合金的管重量比較輕，顏色也多，價格也比較便宜，但是管的表面容易磨損，不及不銹鋼的管耐用。不銹鋼的管重量比較重，顏色也少，但它比較耐用，聲音比鋁合金的管沉些，所以一般玩改裝的朋友都喜歡選不銹鋼的管。不過材料本身價格較高，還是無法讓其真正高度普及化。碳纖維的管重量比較輕，一般都是黑色碳纖維為主，耐用度也比不上不銹鋼的。</p><p style="text-indent:25px">防止消聲器銹蝕：雨天行駛或洗車時，防止消聲器進水，如不慎進水，應啟動車輛，進行熱車10分鐘，盡量排除進水，烘干消聲器。可以在消聲器中涂抹防銹油，來防止生銹，操作步驟如下：拆下消聲器，堵住消聲器中的較低排水孔，從消聲器與發(fā)動機項鏈的法蘭處加入約50ML防銹油，搖動消聲器讓防銹油均勻的進入筒體，裝上消聲器，啟動發(fā)動機后，由于消聲器溫度上升，防銹油受熱后發(fā)生揮發(fā)，消聲器尾部會冒藍煙。20KM后會消失，藍煙消失后取消排水孔的堵塞物。新車可以進行一次防銹處理，后期每年可進行一次保養(yǎng)處理。微穿孔板式消聲器可以控制消聲器的頻譜性能。</p><div

style="text-indent:25px">消聲器的機殼或管道輻射的噪聲可能傳入消聲器后端，致使消聲效果下降，必要時，可在消聲器外殼或部分管道上做隔聲處理。消聲器法蘭和風機法蘭連接處應加彈性墊并注意密封，以免漏聲、漏氣，同時也能減少剛性連接的振動傳聲。在通風空調(diào)系統(tǒng)中，消聲器應盡量安裝于靠近使用房間的地方。消聲器片間流速應適當。風機消聲器片間平均流速可認為與風機管道流速相等。用于民用建筑，消聲器片間流速通常取3-12m/s；工業(yè)方面，消聲器片間流速通常取12-25m/s，較大不得超過30m/s。流速不同，消聲器護面結構應不同。平均流速小于10m/s時，多孔吸聲材料的護面可用防火布或金屬絲網(wǎng)罩起來；平均流速為10-23m/s時，可選用金屬穿孔板護面；當平均流速為23-45m/s時，可選用玻璃絲布和金屬穿孔板護面；當平均流速為45-120m/s時，可采用雙層金屬穿孔板和鋼絲棉護面，穿孔率應大于20%。消聲器能吸收排管的垂直和水平熱位移，保證排氣。梧州消聲器供應公司</p><p style="text-indent:25px">抗噴阻型消聲器對各頻噪聲效果優(yōu)越。梧州消聲器供應公司</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。結構：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。轎車消聲器的總容積為發(fā)動機排量的8~12倍。梧州消聲器供應公司</p><p
