style="text-indent:25px">摩托車(chē)消聲器是摩托車(chē)發(fā)展史上不可或缺的零部件，摩托車(chē)消聲器發(fā)展歷史也與摩托車(chē)一樣久遠(yuǎn)。發(fā)動(dòng)機(jī)在做功后，緊接著是排氣沖程。排氣是將氣缸內(nèi)的廢氣排出。由于這時(shí)的廢氣是高溫高壓，由排氣管直接排出，將是很大的噪音。而消音器的作用簡(jiǎn)單的說(shuō)，就是發(fā)動(dòng)機(jī)排出的氣流在消音器內(nèi)經(jīng)過(guò)多孔的管子與隔板并反復(fù)的回繞后，噪音逐漸衰減，達(dá)到消音的目的。消聲器是一個(gè)多級(jí)分流分壓的組合體。其工作原理大致如下：進(jìn)氣：此時(shí)進(jìn)氣門(mén)打開(kāi)，活塞下行，汽油和空氣的混合氣被吸進(jìn)汽缸內(nèi) .壓縮：此時(shí)進(jìn)氣門(mén)和排氣門(mén)同時(shí)關(guān)閉，活塞上行，混合氣被壓縮。燃燒：當(dāng)混合氣被壓縮到較小時(shí)火花塞跳火點(diǎn)燃混合氣，燃燒產(chǎn)生的壓力推動(dòng)活塞下行并帶動(dòng)曲軸旋轉(zhuǎn)。排氣：當(dāng)活塞下行到較低點(diǎn)時(shí)排氣門(mén)打開(kāi)，廢氣排出，活塞繼續(xù)上行把多余的廢氣排出。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。茂名消聲器哪家好</p><p

style="text-indent:25px">氣缸消聲器的定義：消音器是一種允許氣流通過(guò)而能使聲能衰減的裝置，能夠降低氣流通道上的空氣動(dòng)力性噪聲。氣缸消聲器的選擇方法：具有較好的消聲性能，即要求消聲器具有較好的消聲頻率特性，噪聲一般控制在74~80dB之間(當(dāng)供氣為0.6MPa,距離為1m時(shí)測(cè)得的噪聲）具有良好的空氣動(dòng)力性能，消聲器對(duì)氣流的阻力損失要小結(jié)構(gòu)簡(jiǎn)單，便于加工，經(jīng)濟(jì)耐用，無(wú)再生噪聲。在設(shè)計(jì)和選擇消聲器時(shí)，應(yīng)合理選擇通過(guò)消聲器的氣流速度。對(duì)空調(diào)系統(tǒng)，流過(guò)的氣流速度可取≤6m/s;對(duì)一般系統(tǒng)宜取6~10m/s;對(duì)工業(yè)鼓風(fēng)機(jī)或其他氣動(dòng)設(shè)備可取10~20m/5s;對(duì)高壓排空消聲器則可大于20m/s。茂名消聲器哪家好</p><p
