柴油發(fā)電機(jī)組曲柄連桿機(jī)構(gòu)常見的異常響聲有活塞環(huán)響、活塞敲缸響、連桿軸承響、活塞銷響等。比如說，發(fā)電機(jī)活塞敲缸會(huì)導(dǎo)致柴油機(jī)燃油和機(jī)油消耗量增加，竄機(jī)油。當(dāng)活塞敲缸嚴(yán)重時(shí)，還會(huì)打碎活塞，敲壞氣缸，甚至使連桿斷裂，打壞缸體。下面為大家介紹柴油發(fā)電機(jī)組活塞敲缸響的部分診斷與處理方法。 </p> <p> 1、打開加機(jī)油加注口端蓋，將柴油機(jī)轉(zhuǎn)速調(diào)整在異響聲明顯、清晰的范圍內(nèi)，觀察加機(jī)油口處是否冒yan，排氣管是否冒藍(lán)yan。用旋具抵在不設(shè)氣門推桿一側(cè)的缸體上部，如所觸處活塞敲擊，就可能聽到像用小錘敲水泥地一樣的有振動(dòng)的敲擊聲。 </p> <p> 2、逐缸斷油，若斷到某個(gè)缸時(shí)聲音明顯減小或者消失，而當(dāng)恢復(fù)其供油時(shí)又能聽到敲擊聲，說明是該缸出現(xiàn)的活塞敲擊，應(yīng)及時(shí)修理。北京柴油發(fā)電機(jī)組小型從結(jié)構(gòu)上看，風(fēng)機(jī)消聲器、空壓機(jī)消聲器大都是阻性或炕復(fù)式消聲器。</p><div

康明斯柴油發(fā)電機(jī)組冷卻液循環(huán)故障是發(fā)電機(jī)組的常見故障之一，針對(duì)循環(huán)故障原因有很多，下面做出部分的排查解決。 </p> <p> 1、康明斯柴油發(fā)電機(jī)組水泵故障。首先我們要先檢查水泵作用是否良好，要是發(fā)現(xiàn)水泵傳動(dòng)齒軸磨損過限時(shí)，說明水泵已失去作用，應(yīng)該更換后才可以循環(huán)正常。 </p> <p> 2、康明斯柴油發(fā)電機(jī)組冷卻液液面太低或者不符合規(guī)定。液面太低可直接造成冷卻液溫度升高讓冷卻液不循環(huán)，冷卻液按規(guī)定是50%防凍液+50%軟化水+DCA4，要是不符合規(guī)定將會(huì)造成管路堵塞，管壁內(nèi)產(chǎn)生銹跡，讓冷卻液不能正常循環(huán)。柴油發(fā)電機(jī)組微穿孔板消聲器可受較高氣流速度的沖擊，耐高溫、不怕水，能耐一定粉塵。</p><div

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，若氣缸壁的拉痕不深，可用油石磨光，換上同型號(hào)、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，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)。某些用電單位沒有網(wǎng)電供應(yīng)，如遠(yuǎn)離大陸的海島，荒漠高原的軍營、工作站、雷達(dá)站等，就需要配置自備電源。北京柴油發(fā)電機(jī)組小型</p><p

柴油發(fā)電機(jī)組曲軸軸向間隙也稱曲軸的端隙，是指軸承承推端面與軸頸與軸頸定位軸肩之間的軸向間隙。那么發(fā)電機(jī)組曲軸軸向間隙的檢查方法是什么呢？ </p> <p> 柴油發(fā)電機(jī)組曲軸軸向間隙是為了適應(yīng)內(nèi)燃機(jī)在工作中機(jī)件熱膨脹時(shí)的需要而定的。間隙過小，會(huì)使機(jī)件膨脹而卡死；間隙過大，前后竄動(dòng)，則給活塞連桿組的機(jī)件帶來不正常的磨損，止推墊圈表面逐漸磨損，使間隙改變，形成軸向位移，因此，在裝配曲軸時(shí)，應(yīng)進(jìn)行曲軸軸向間隙的檢查。 </p> <p> 檢查時(shí)，先將柴油發(fā)電機(jī)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，然后用厚薄規(guī)在初道曲軸臂與止推墊圈之間測(cè)量。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(jìn)行調(diào)整。北京柴油發(fā)電機(jī)組小型</p><p
