柴油發(fā)電機組曲柄連桿機構(gòu)常見的異常響聲有活塞敲缸響、活塞環(huán)響、活塞銷響、連桿軸承響、曲軸軸承響和拉缸響等。通常，活塞敲缸異響發(fā)生的部位在柴油機氣缸的上部，一般是在活塞做功沖程開始的瞬間，活塞在氣缸內(nèi)擺動或竄動，其頭部或裙部與缸壁、缸蓋相碰撞產(chǎn)生的，其響聲有以下特點： </p> <p>

柴油發(fā)電機組拉缸響使柴油機的動力性和經(jīng)濟(jì)性變差，嚴(yán)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。浙江靜音型柴油發(fā)電機價錢柴油發(fā)電機組能夠滿足客戶的電力需求。</p><div style="width:100%;text-align:

柴油發(fā)電機組軸軸承響聲大是極為嚴(yán)重的故障之一，發(fā)現(xiàn)軸承響聲后應(yīng)立即停機檢修，以防出現(xiàn)較大問題。其檢修方法如下： </p> <p> 方法一：待柴油發(fā)電機的發(fā)動機冷卻至常溫后，放出機油，拆下油底殼，檢視曲軸軸承有無松曠、燒毀，如松曠或燒毀，應(yīng)予以更換。 </p> <p> 方法二：如因松曠而使?jié)櫥涂族e位時，應(yīng)在軸瓦背而墊薄銅片，并留出油孔位置；如螺栓松動應(yīng)加固。 </p> <p> 方法三：如缺潤滑油應(yīng)補充到規(guī)定要求；如曲軸軸向位移，則是曲軸端隙過大，應(yīng)按要求更換推力墊片，使曲軸端隙達(dá)到規(guī)定值。一般曲軸端隙值要求在0.05-0.25mm，較大間隙值小超過0.30mm。 </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(fù)荷工況下尤為明顯，同時伴有機體振動；大負(fù)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(jìn)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>

著火敲擊聲是由于柴油發(fā)電機組著火滯后期過長，壓力升高率過大，致使發(fā)動機工作粗暴而形成的。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(fù)荷工況下尤為明顯，同時伴有機體振動；大負(fù)荷高轉(zhuǎn)速時響聲相對減小，運轉(zhuǎn)也相對平穩(wěn)。那么柴油發(fā)電機發(fā)出著火敲擊聲的原因是什么呢？ </p> <p> 原因一：噴油提前角過大。 </p> <p> 原因二：柴油的標(biāo)號不符合標(biāo)準(zhǔn)，十六烷值太低。 </p> <p> 原因三：噴油量過大或各缸供油間隔角不均。 </p> <p> 原因四：噴油器的霧化質(zhì)量太差。 </p> <p> 原因五：柴油機工作溫度過低。江蘇發(fā)電機機組廠家</p><p
