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(fēng)機法蘭連接處應(yīng)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(fēng)空調(diào)系統(tǒng)中，消聲器應(yīng)盡量安裝于靠近使用房間的地方。消聲器片間流速應(yīng)適當(dāng)。風(fēng)機消聲器片間平均流速可認(rèn)為與風(fēng)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(jié)構(gòu)應(yīng)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(dāng)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(dāng)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(yīng)大于20%。</p><p style="text-indent:25px">消聲器的工作原理主要是讓推動彈丸做功的燃氣在一個相對于管要大得多的封閉空間內(nèi)釋放熱能，以減少壓強和流速，避免對口附近的空氣產(chǎn)生過大的沖擊（也就是產(chǎn)生口噪音——發(fā)射時的主要噪音）?，F(xiàn)在世界上通用的消音器其原理基本上是通過降低燃氣沖出口的速度和流量來降低較大峰值來消音。具體的措施是，在消音器內(nèi)裝上若干帶有小孔的消音隔板或鋼絲，或在口安裝一個口徑比小的橡膠消音器等等來降低口的較大峰值（也就是提前將燃氣要做的功傾瀉掉），同時使用低于音速的彈（低速彈）降低在空氣中飛行的呼嘯聲。不管你用什么方法來降低的聲音，總是要**的一些性能，同時使自動機工作不正常。所以消音器并沒有什么制退的作用，也不會減小后坐力。現(xiàn)在的一般在膛口處加裝了籠型或桶型消焰器，通過改變排焰孔的切削角度可以實現(xiàn)一定的制退作用，但是裝上消音器后膛口裝置的制退作用也消失了。消音器除了通常的消音和消焰作用外，還有一個附加的好處——在膛口處增加了一個重物，可以抑止口上跳，減少散布提高精度。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">在空調(diào)系統(tǒng)中靜壓箱和消聲器是常見的，是用于通風(fēng)設(shè)備出入口、多支風(fēng)管匯合或分支處，為了保證氣流均勻，一般應(yīng)設(shè)靜壓箱。靜壓箱的工作原理是依據(jù)截面的變化，將氣流的動壓轉(zhuǎn)變?yōu)闅饬鞯撵o壓。靜壓箱一般根據(jù)所需厚度的鋼材、根據(jù)設(shè)計加工制作，一般制成矩形。消聲器的作用：消聲器是一種既能允許氣流通過，又能有效地阻止或減弱聲能向外傳播的裝置。當(dāng)噪聲源在室內(nèi)產(chǎn)生的聲壓級高于允許的噪聲標(biāo)準(zhǔn)時，就需要根據(jù)各頻帶要求消除的聲壓級選擇的消聲裝置，消除超出室內(nèi)的噪聲標(biāo)準(zhǔn)范圍的那部分聲能。消聲器是根據(jù)不同的消聲原理設(shè)計成的管道構(gòu)件，按所采用的消聲原理可分為阻性消聲器、抗性消聲器、共振消聲器和原合消聲器等類型。在通風(fēng)空調(diào)系統(tǒng)中的動力設(shè)備，如新風(fēng)機等會產(chǎn)生空氣動力噪聲。氣流經(jīng)過風(fēng)管系統(tǒng)的各個管件、部件時，會產(chǎn)生氣流再生噪聲。當(dāng)風(fēng)機的噪聲在經(jīng)過各種自然消減后仍然不能滿足室內(nèi)噪聲標(biāo)準(zhǔn)時，就必須在管路上設(shè)置專門的消聲裝置，并使其在各頻帶的消聲量能基本滿足設(shè)計需要。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(fù)合式消聲器。柳州消聲器制造廠家</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(fù)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(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。陽江消聲器有哪些品牌</p><p
