柴油發(fā)電機組曲軸軸向間隙是為了適應(yīng)內(nèi)燃機在工作中機件熱膨脹時的需要而定的。間隙過小，會使機件膨脹而卡死；間隙過大，前后竄動，則給活塞連桿組的機件帶來不正常的磨損，止推墊圈表面逐漸磨損，使間隙改變，上海柴油發(fā)電機組銷售批發(fā)，形成軸向位移，因此，在裝配曲軸時，應(yīng)進行曲軸軸向間隙的檢查。 </p> <p> 檢查時，先將柴油發(fā)電機組曲軸定位軸肩和軸承的承推端面的一邊靠合，用撬棍撬擠曲軸后端，上海柴油發(fā)電機組銷售批發(fā)，然后用厚薄規(guī)在初道曲軸臂與止推墊圈之間測量，上海柴油發(fā)電機組銷售批發(fā)。曲軸軸向間隙一般為0.05-0.25mm。如軸向間隙過大或過小，則應(yīng)更換或修整止推墊圈進行調(diào)整。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。上海柴油發(fā)電機組銷售批發(fā)</p><div

方法一：如果采用半斷油試驗，響聲只減弱而不消失，必須完全斷油后響聲才能消失，則說明是該缸供油時間過早或噴油器霧化質(zhì)量差引起的著火敲擊響聲。應(yīng)注意檢查該缸的供油時間(與初缸的供油間隔)和該缸噴油器的噴霧情況。 </p> <p> 方法二：因個別缸供油量過大引起的著火敲擊聲，還可采用冷啟動后，用手摸對應(yīng)缸的排氣歧管，大負荷有敲擊聲；用手摸噴油器下部及其附近的溫度比其他缸熱，則說明是該缸供油量過大。還可以用手握高壓油管，感覺脈動較大的則是該缸供油量過大。 </p> <p> 方法三：個別缸供油量過大和供油時間過早，應(yīng)拆下噴油泵在試驗臺上調(diào)試該缸的供油量和供油提前角，并對其他各缸的供油量、供油提前角和供油間隔角進行檢查。北京供應(yīng)發(fā)電機靜音式發(fā)電機組電流不平衡的原因：系統(tǒng)單相負荷太大，如有容量巨大的單相負載現(xiàn)象。</p><div style="width:100%;text-align:

柴油發(fā)電機組氣門的常見故障有：氣門接觸面的磨損、氣門頭部偏磨、氣門桿的磨損與彎曲變形等等。 </p> <p> 故障一：氣門接觸面的磨損。 </p> <p> 1)空氣中的塵?；蛉紵s質(zhì)滲入或滯留在接觸面間。 </p> <p> 2)內(nèi)燃機在工作過程中，氣門將不停地開啟和關(guān)閉，由于氣門與氣門座的撞擊、敲打，引起工作面的起槽和變寬。 </p> <p> 3)進氣門直徑較大，在燃氣爆發(fā)壓力作用下產(chǎn)生變形。 </p> <p> 4)磨后氣門邊緣厚度下降。 </p> <p> 5)排氣門受高溫氣體的沖擊，使工作面溶蝕，出現(xiàn)斑點和凹陷。 </p> <p> 故障二：氣門頭部偏磨。 </p> <p> 氣門桿在氣門導(dǎo)管內(nèi)不斷摩擦，使配合間隙增大，而在管內(nèi)晃動，引起氣門頭部的偏磨。 </p> <p> 故障三：氣門桿的磨損與彎曲變形。 </p> <p> 氣缸內(nèi)的氣體壓力以及凸輪通過挺柱對氣門的撞擊。 </p> <p> 所有這些故障，均可造成進排氣門關(guān)閉不嚴而漏氣。 </p><p style="text-indent:25px">汽車發(fā)電機常見故障：充電電流不穩(wěn)。故障解決辦法：在發(fā)動機怠速以上轉(zhuǎn)速運轉(zhuǎn)時，電流表指針左右擺動，顯示間歇充電(有時充電有時又不充電的現(xiàn)象)，一般為發(fā)電機的端電壓不穩(wěn)定。首先應(yīng)檢查各連接線頭是否松動和接觸不良；皮帶是否過松以及蓄電池的極樁有無松動。若無異常再檢查調(diào)節(jié)器觸點是否燒蝕、臟污，線圈或電阻有無接觸不良、斷路等；仍無異常，則應(yīng)拆檢發(fā)電機內(nèi)部的技術(shù)狀況，并逐項修復(fù)。發(fā)電機中速以上運轉(zhuǎn)時，電流表指示充電，但指針不斷左右擺動，充電電流時大時小，應(yīng)予檢修。柴油發(fā)電機組復(fù)合式消聲器既有阻性吸聲材料，又有共振器、擴張式、穿孔屏等聲學(xué)濾波器件。</p><div

連桿軸承是柴油發(fā)電機中必不可少的配件，它可以支撐整個機組的機械旋轉(zhuǎn)，減少發(fā)電機組的摩擦帶來的傷害。然而，用戶在使用機組過程中，突然加速時，有時候會聽到"噹噹噹"的響聲，當轉(zhuǎn)速和負荷增大時，響聲也增大。遇到這種情況的時候，如何診斷與處理呢？ </p> <p> 1、查看機油表壓力，若過低并伴隨有"噹噹噹"的聲音，則應(yīng)進一步檢查。 </p> <p> 2、將加機油口蓋打開，有聽診器時將聽診器插入加機油口內(nèi)，可聽到敲擊聲，嚴重時在柴油機附近便可聽清，當突然加速時，響聲更為突出。 </p> <p> 3、將柴油機轉(zhuǎn)速稍提高，避開怠速工作時的粗暴聲，逐缸斷油細聽，若斷油后的聲音減輕，再迅速供油的瞬間發(fā)出"噹"的響聲，則說明該缸連桿軸承響。那起動馬達的和發(fā)電機常見故障、故障原因及排除方法有哪些呢？北京供應(yīng)發(fā)電機</p><p style="text-indent:25px">汽車運轉(zhuǎn)時由發(fā)電機、調(diào)節(jié)器、蓄電池等組成充電系統(tǒng)來工作，可通過充電指示燈或電流表來判斷是否工作正常。上海柴油發(fā)電機組銷售批發(fā)</p><p> 什么叫做柴油發(fā)電機組“游車”，指的是柴油發(fā)電機組在低速以及中速的范圍內(nèi)出現(xiàn)周期較長而且較有規(guī)律的時快時慢現(xiàn)象，這是調(diào)速反應(yīng)過分滯后于實際轉(zhuǎn)速變化的結(jié)果。柴油發(fā)電機組游車的原因主要有下面三種。 </p> <p> 1、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。 </p> <p> 2、柴油發(fā)電機組供油齒桿不夠靈活。 </p> <p> 3、柴油發(fā)電機組穩(wěn)速彈簧調(diào)整不恰當。這與怠速不穩(wěn)定時穩(wěn)速彈簧調(diào)整不當相似，這種情況之所以表現(xiàn)出“游車”，是由于穩(wěn)速彈簧和供油齒桿不可以共同靈活的起作用。上海柴油發(fā)電機組銷售批發(fā)</p><p
