1、如發(fā)現(xiàn)可疑缸活塞敲擊，可將該缸噴油器卸下來，向氣缸內(nèi)加入少量機(jī)油，轉(zhuǎn)動(dòng)幾圈曲軸，再裝回噴油器后啟動(dòng)柴油機(jī)。若敲擊聲消失或減弱，運(yùn)轉(zhuǎn)一會(huì)兒敲擊聲再度出現(xiàn)，則可確認(rèn)是該缸有敲缸。 </p> <p> 2、若敲缸聲*發(fā)生在冷機(jī)啟動(dòng)運(yùn)行時(shí)，柴油機(jī)溫度正常后聲音消失，可以暫不維修繼續(xù)使用，等到適當(dāng)時(shí)機(jī)再行修理。 </p> <p> 3、若柴油機(jī)低溫時(shí)響聲不清晰，當(dāng)溫度升高后，怠速運(yùn)轉(zhuǎn)有"嘎嘎"聲，并伴有機(jī)體抖動(dòng)，而且溫度越高，響聲越大，則說明活塞變形或潤滑不良，應(yīng)及時(shí)修理。 </p> <p> 4、因潤滑不良而出現(xiàn)的敲缸，還應(yīng)找出潤滑系統(tǒng)故障原因予以檢修。 </p> <p> 5，廣東1500千瓦發(fā)電機(jī)、在拆下氣缸蓋，抽出活塞檢查時(shí)，廣東1500千瓦發(fā)電機(jī)，若發(fā)現(xiàn)氣缸嚴(yán)重失圓、拉傷、連桿彎曲變形、活塞銷與連桿襯套配合過緊，廣東1500千瓦發(fā)電機(jī)、連桿軸瓦與連桿軸頸配合間隙過小、活塞頂積炭過多等，應(yīng)進(jìn)行相應(yīng)處理或換件修理。靜音式發(fā)電機(jī)組電流當(dāng)不平衡超限且超過規(guī)定工作時(shí)間時(shí)，負(fù)序信號(hào)裝臵發(fā)“發(fā)電機(jī)不對(duì)稱過負(fù)荷”信號(hào)。廣東1500千瓦發(fā)電機(jī)</p><div

style="text-indent:25px">汽車發(fā)電機(jī)常見故障：發(fā)電機(jī)不發(fā)電。故障解決辦法：發(fā)電機(jī)不發(fā)電的主要原因是：整流二極管擊穿短路或斷路；激磁繞組短路或斷路；三相定子繞組相問短路或搭鐵；轉(zhuǎn)子滑環(huán)嚴(yán)重氧化臟污，炭刷架損壞或炭刷在刷架中卡住。發(fā)動(dòng)機(jī)在中等以上轉(zhuǎn)速時(shí)，電流表指針指示不充電，充電指示燈亮，首先要考慮蓄電池充電情況，若充電不足則為發(fā)電裝置故障。不充電除了傳動(dòng)皮帶過松打滑，一般要檢查發(fā)電機(jī)本身不發(fā)電或調(diào)節(jié)器故障，以及充電電路斷路故障。如發(fā)電機(jī)內(nèi)部整流脫落或電樞接線柱底部與二極管元件板接觸處不通；二極管擊穿短路，造成定子繞組燒損；電刷在炭刷架內(nèi)卡住接觸不良，或磁場繞組斷路等。廣東1500千瓦發(fā)電機(jī)靜音式發(fā)電機(jī)組電流不平衡的原因：發(fā)電機(jī)及它的回路一相斷開或者斷路器一相接觸不良。</p><div

</p> <p> 原因一：使用不規(guī)范，在發(fā)電機(jī)組的磨合期未按規(guī)定操作，甚至使柴油機(jī)超負(fù)荷運(yùn)轉(zhuǎn)，溫度過高，破壞了氣缸與活塞(環(huán))間的潤滑油膜，引起活塞環(huán)與氣缸壁間拉傷。嚴(yán)重時(shí)活塞膨脹過大，與缸壁咬住而拉傷。 </p> <p> 原因二：保養(yǎng)不規(guī)范，未及時(shí)去除活塞環(huán)上的積炭，使活塞環(huán)卡在環(huán)槽內(nèi)失去彈性。 </p> <p> 原因三：刮除積炭時(shí)未去除干凈，使極硬的積炭顆粒落人缸隙，形成磨料拉傷。 </p> <p> 原因四：維修后裝配時(shí)，活塞與氣缸壁的間隙過小，活塞環(huán)的端隙過小。 </p> <p> 原因五：活塞環(huán)斷裂出現(xiàn)刃角或活塞銷卡簧脫落，使活塞銷竄出拉傷氣缸。 </p> <p> 原因六：冷卻系統(tǒng)或潤滑系統(tǒng)故障，使氣缸散熱和潤滑不良。 </p> <p> 原因七：冷啟動(dòng)或低溫下突然加大負(fù)荷，燃油霧化不良，致使過多燃油進(jìn)入氣缸，沖洗缸壁上的潤滑油膜，引起拉缸。 </p> <p> 原因八：連桿變形導(dǎo)致活塞在缸內(nèi)歪斜。 </p><p
