階段一：初期拉缸的柴油機(jī)響聲不很清晰，但有機(jī)油竄入燃燒室，使積炭增多。壓縮時(shí)燃?xì)饴┑角S箱，使機(jī)油變質(zhì)。加速時(shí)，從加機(jī)油口處及曲軸箱通風(fēng)管處竄油yan。此時(shí)可確診為初期拉缸。此時(shí)，應(yīng)對(duì)活塞連桿組清洗檢查，并更換機(jī)油和機(jī)油濾芯，清洗油底殼。裝復(fù)后經(jīng)磨合可再使用一段時(shí)間，氣缸的密封性會(huì)有所改善，但動(dòng)力性不如拉缸前。 </p> <p> 階段二：中期拉缸的柴油機(jī)漏氣嚴(yán)重，類似敲缸的異響聲較為清楚，打開加機(jī)油口蓋，大量油yan有節(jié)奏地冒出，排氣管排濃藍(lán)yan，同時(shí)怠速不良。當(dāng)用斷油法檢查時(shí)，異響聲減弱。若中期拉缸發(fā)生于多缸，用斷油法檢查時(shí)，異響聲雖能減弱，但不能消失。對(duì)于中期拉缸，北京大型柴油發(fā)電機(jī)組，若氣缸壁的拉痕不深，可用油石磨光，換上同型號(hào)，北京大型柴油發(fā)電機(jī)組、同質(zhì)量的活塞和同規(guī)格的活塞環(huán)即可繼續(xù)使用，異響聲也會(huì)極大減小。 </p> <p> 階段三：后期拉缸有明顯的敲缸和竄氣聲，北京大型柴油發(fā)電機(jī)組，動(dòng)力性能也明顯下降。當(dāng)轉(zhuǎn)速增加時(shí)響聲也隨之加重，聲音雜亂，柴油機(jī)出現(xiàn)抖動(dòng)，嚴(yán)重時(shí)會(huì)使活塞在缸內(nèi)打碎或損壞缸體。對(duì)于這種狀況必須更換氣缸套、活塞和活塞環(huán)。柴油發(fā)電機(jī)組消聲器種類很多，但究其消聲機(jī)理，又可以把它分為六種主要的類型。北京大型柴油發(fā)電機(jī)組</p><div

著火敲擊聲是由于柴油發(fā)電機(jī)組著火滯后期過長(zhǎng)，壓力升高率過大，致使發(fā)動(dòng)機(jī)工作粗暴而形成的。急加速時(shí)，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(shí)伴有機(jī)體振動(dòng)；大負(fù)荷高轉(zhuǎn)速時(shí)響聲相對(duì)減小，運(yùn)轉(zhuǎn)也相對(duì)平穩(wěn)。那么柴油發(fā)電機(jī)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(hào)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(jī)工作溫度過低。 </p><p> 康明斯柴油發(fā)電機(jī)組冷卻液循環(huán)故障如何解決？下面這幾點(diǎn)需要了解。 </p> <p> 1、康明斯柴油發(fā)電機(jī)組節(jié)溫器故障。發(fā)動(dòng)機(jī)燃燒室內(nèi)裝有節(jié)溫器，目的在于控制發(fā)動(dòng)機(jī)燃燒室溫度，節(jié)溫器一定要在規(guī)定溫度完全打開有助于小循環(huán)，要是沒有節(jié)溫器，冷卻液無法保持循環(huán)溫度，或許會(huì)產(chǎn)生低溫報(bào)警。 </p> <p> 2、康明斯柴油發(fā)電機(jī)組冷卻系統(tǒng)中混有空氣，導(dǎo)致管路不暢通，膨脹水箱上吸氣閥、排氣閥損壞也直接影響循環(huán)，這個(gè)時(shí)候需要經(jīng)常檢查它們的壓力值是不是符合規(guī)定，吸氣壓力是10kpa，排氣壓力是40kpa，此外，排氣管路是不是暢通也是影響循環(huán)的關(guān)鍵原因。 </p> <p> 3、康明斯柴油發(fā)電機(jī)組散熱器散熱片堵塞或損壞。散熱風(fēng)扇不起作用或者散熱片堵塞，讓冷卻液溫度降不下，散熱片銹損，出現(xiàn)漏液現(xiàn)象，也可導(dǎo)致循環(huán)不良。發(fā)電機(jī)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。</p><div style="width:100%;text-align:
