方法一：若根據(jù)故障現(xiàn)象初步判定為柴油發(fā)電機組的柴油機著火敲擊聲，可首先檢查柴油機的工作溫度，然后檢查供油時間(噴油提前角)和柴油的品質(zhì)。 </p> <p> 方法二：采用半斷油試驗，即擰松噴油器高壓油管接頭，河南120kw柴油發(fā)電機，使部分油噴在外而，河南120kw柴油發(fā)電機，以減少向缸內(nèi)的供油量。如果響聲和排煙消失，河南120kw柴油發(fā)電機，則說明是該缸供給量過大而產(chǎn)生的著火敲擊聲。 </p> </p> <p> <br />

style="text-indent:25px">汽車的發(fā)電機如同人的心臟一樣，是整體中重要的部位，如同空氣和水對人不可或缺，所以對其做好維護保養(yǎng)很重要，這幾點需要了解下。1、電刷接觸面不平，可用細砂布打平。彈簧的彈性不足，電刷磨損過多時，均須更換新件。電刷太短而無破損，可用墊片塞入支架，使其與整流器密合。2、電刷支架絕緣體損壞，需要另配新件。電刷交觸面不平，可用細砂布打平。怎么保養(yǎng)你的汽車彈簧的彈性缺少，電刷磨損過少時，均須更換新件。電刷太短而無破損，可用墊片塞入收架，使其與整流器密合。3、發(fā)電機的極柱松動，必須馬上緊固，如果是絕緣不良，應(yīng)拆下進行修整。江蘇450千瓦發(fā)電機汽車發(fā)電機故障一般有：1、充電電流過??；2、充電電流過大；3、充電電流不穩(wěn)定；4、發(fā)電機不發(fā)電。</p><div

柴油發(fā)電機的柴油機在同樣轉(zhuǎn)速下，活塞銷的響聲比活塞敲缸的聲音更尖銳清脆而且連續(xù)，是"托托托"的金屬敲擊聲，而且是上下雙響。怠速運轉(zhuǎn)時加速，響聲**清楚。那么造成這種異常響聲的原因是什么呢？ </p> <p> 原因一：柴油發(fā)電機活塞銷與銷座孔配合松曠。 </p> <p> 原因二：柴油發(fā)電機活塞銷與連桿襯套磨損過甚，使其配合間隙過大。 </p> <p> 原因三：柴油發(fā)電機的機油壓力過低，潤滑不良引起活塞銷嚴重燒蝕。 </p> <p> 原因四：柴油發(fā)電機的活塞銷卡環(huán)脫落，使活塞銷自由竄動。 </p><p style="text-indent:25px">柴油發(fā)電機組調(diào)速器內(nèi)部杠桿因為連接銷孔磨損而導(dǎo)致松弛，造成柴油發(fā)電機組“游車”的現(xiàn)象。這種情況下，讓增減供油量的雙向調(diào)速運動產(chǎn)生了太多的變向滯后。發(fā)動機工作的時候，調(diào)速反應(yīng)是肯定會滯后于實際轉(zhuǎn)速變化的，可是滯后量不可以太大，不然就會產(chǎn)生較大的調(diào)節(jié)振幅。調(diào)節(jié)振幅太大，就是當轉(zhuǎn)速已因為供油量的增減而造成轉(zhuǎn)速升降的時候仍將繼續(xù)增減燃油，直到轉(zhuǎn)速超過調(diào)速器調(diào)節(jié)范圍較大之后，它強烈的反饋信號才通過調(diào)速器實現(xiàn)反向調(diào)節(jié)的反應(yīng)，結(jié)果讓調(diào)速反應(yīng)超出了預(yù)定的范圍，導(dǎo)致了轉(zhuǎn)速在它某一定值附近反復(fù)有規(guī)律升降的“游車”現(xiàn)象。柴油發(fā)電機組消聲器可以分為阻性消聲器、抗性消聲器、阻抗復(fù)合式消聲器、擴容減壓、小孔噴注式消聲器等。</p><div

柴油發(fā)電機組拉缸響使柴油機的動力性和經(jīng)濟性變差，嚴重時活塞會卡死在氣缸內(nèi)，使發(fā)動機不能正常工作。氣缸被活塞拉傷會使機油竄入燃燒室，致使燃燒室積炭，同時會使燃油漏至油底殼沖淡機油，有時候可從機油口處看見有燃油味的油煙和喘氣現(xiàn)象。那么柴油發(fā)電機拉缸響的診斷與處理方法是什么呢？ </p> <p> 1、柴油發(fā)電機組運轉(zhuǎn)中，出現(xiàn)類似敲缸的聲音，但響聲不隨柴油機的溫度升高而減弱，即可初步斷定為拉缸響。 </p> <p> 2、拆卸氣缸蓋，檢查缸壁的拉傷情況，一般可分為初期、中期和后期三個階段。發(fā)電機的形式很多，但其工作原理都基于電磁感應(yīng)定律和電磁力定律。河南120kw柴油發(fā)電機</p><p
