class="box"><p><p> 柴油發(fā)電機發(fā)出著火敲擊聲的診斷與處理方法有哪些？下面分享其中三種方法，湖北車載發(fā)電機。 </p> <p> 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，湖北車載發(fā)電機，湖北車載發(fā)電機，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。做好柴油發(fā)電機組降噪工作很有必要。湖北車載發(fā)電機</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖北車載發(fā)電機,電" src="https://tyunfile.71360.com/UploadFile/dxdqjt/637251367769062500/1105184.jpg"></div><p> 柴油發(fā)電機組曲軸軸承的響聲較連桿軸承的響聲沉重而有力，突然加速時才發(fā)出沉悶的"嘡嘡"聲，嚴重時還伴有機體振動。響聲部位發(fā)生在氣缸體的下部。響聲隨轉(zhuǎn)速、負荷的增大而增大，如發(fā)動機滿載時，響聲尤為明顯。 </p> <p> 原因一：柴油發(fā)電機組曲軸軸承與軸頸磨損嚴重或軸承蓋螺栓擰緊力矩不足而松曠，造成徑向問隙過大，使曲軸上下跳動而發(fā)出撞擊聲。 </p> <p> 原因二：柴油發(fā)電機組曲軸軸承在裝配時間隙過小，使表面摩擦過熱而燒毀軸承合金。 </p> <p> 原因三：柴油發(fā)電機組軸承與座孔的配合出現(xiàn)松動現(xiàn)象，使?jié)櫥涂卒佄?，造成潤滑油供?yīng)不足?；驖櫥唾|(zhì)量太差，使?jié)櫥湍るy以形成，造成摩擦表面出現(xiàn)半干摩擦或干摩擦。 </p> <p> 原因四：柴油發(fā)電機組曲軸推力墊片過薄，形成曲軸軸向位移。 </p> <p> 原因五：柴油發(fā)電機組軸瓦過長或過短，在工作中變形而轉(zhuǎn)動。湖北車載發(fā)電機靜音式發(fā)電機組電流不平衡的現(xiàn)象：轉(zhuǎn)子的振動和發(fā)熱。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖北車載發(fā)電機,電" src="https://tyunfile.71360.com/UploadFile/dxdqjt/637251367767890625/7346689.jpg"></div><p> 柴油發(fā)電機組活塞環(huán)在長期的使用過程中受到高溫高壓和往復(fù)運動的影響，會使磨損加劇。當磨損達到一定限度時，活塞環(huán)的彈力開始減退，端隙、側(cè)隙和背隙也會逐漸增大，對燃燒室的密封作用會減弱。 </p> <p> 一、柴油機運行時，打開加機油口蓋觀察冒yan情況，若有冒yan現(xiàn)象，則逐缸斷油，若發(fā)現(xiàn)冒yan減輕或消失，響聲也消失，則說明是活塞環(huán)槽磨損過甚或活塞環(huán)斷裂，應(yīng)及時維修。 </p> <p> 二、若斷油試驗響聲沒有變化，而用一字旋具抵著缸蓋部位，感覺有明顯的振動，則是活塞環(huán)碰撞氣缸磨損處的缸肩而發(fā)出的響聲。此時應(yīng)重新修整氣缸，以免活塞環(huán)斷裂。 </p> <p> 三、在熱機檢查時，可從噴油器安裝口處注入少量機油，轉(zhuǎn)動曲軸，再裝回噴油器發(fā)動柴油機，若短時間內(nèi)響聲減弱或消失，則是活塞環(huán)與氣缸壁密封不良。若注入機油后，仍從加機油口冒yan或更甚，則可確診為活塞環(huán)對口(各道活塞環(huán)的開口間隙安裝在同一方向上，安裝時，相鄰兩活塞環(huán)的開口間隙應(yīng)錯開120度-180度)或活塞環(huán)卡在環(huán)槽內(nèi)失去彈性，對此應(yīng)進行維護，徹底去除積炭。 </p><p> <p> 柴油發(fā)電機著火敲擊聲急加速時，發(fā)出尖銳、清脆而連續(xù)的類似金屬的敲擊聲；在怠速或小負荷工況下尤為明顯，同時伴有機體振動；大負荷高轉(zhuǎn)速時響聲相對減小，運轉(zhuǎn)也相對平穩(wěn)。那么如何對這種著火敲擊聲進行診斷與處理呢？下面分享其中兩種方法。 </p> <p> 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，使部分油噴在外而，以減少向缸內(nèi)的供油量。如果響聲和排煙消失，則說明是該缸供給量過大而產(chǎn)生的著火敲擊聲。 </p> </p> <p>
