</p> <p> 原因一：柴油發(fā)電機組連桿軸承與軸頸磨損嚴(yán)重或軸承蓋螺栓松動，破壞了原來的配合問隙，柴油機在做功時受到強大的壓力而產(chǎn)生響聲。 </p> <p> 原因二：柴油發(fā)電機組的柴油機在超負(fù)荷下工作時間過長，軸承的工作溫度過高而燒蝕含金。 </p> <p> 原因三：柴油發(fā)電機組連桿軸承與軸頸的配合間隙過小，浙江柴油靜音發(fā)電機組，機油難以進(jìn)入摩擦表面或機油不易形成油膜，造成軸頸與軸承干摩擦或半干摩擦而燒毀軸承。 </p> <p> 原因四：柴油發(fā)電機組連桿軸瓦過長或過短，在工作中變形而轉(zhuǎn)動。 </p> <p> 原因五：柴油發(fā)電機組連桿軸頸失圓。柴油發(fā)電機組擴容減壓、小孔噴注式消聲器是為降低高溫，浙江柴油靜音發(fā)電機組、高速、高壓排氣噴流噪聲而設(shè)計的排氣放空消聲器。浙江柴油靜音發(fā)電機組</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">柴油發(fā)電機組調(diào)速器內(nèi)部杠桿因為連接銷孔磨損而導(dǎo)致松弛，造成柴油發(fā)電機組“游車”的現(xiàn)象。這種情況下，讓增減供油量的雙向調(diào)速運動產(chǎn)生了太多的變向滯后。發(fā)動機工作的時候，調(diào)速反應(yīng)是肯定會滯后于實際轉(zhuǎn)速變化的，可是滯后量不可以太大，不然就會產(chǎn)生較大的調(diào)節(jié)振幅。調(diào)節(jié)振幅太大，就是當(dāng)轉(zhuǎn)速已因為供油量的增減而造成轉(zhuǎn)速升降的時候仍將繼續(xù)增減燃油，直到轉(zhuǎn)速超過調(diào)速器調(diào)節(jié)范圍較大之后，它強烈的反饋信號才通過調(diào)速器實現(xiàn)反向調(diào)節(jié)的反應(yīng)，結(jié)果讓調(diào)速反應(yīng)超出了預(yù)定的范圍，導(dǎo)致了轉(zhuǎn)速在它某一定值附近反復(fù)有規(guī)律升降的“游車”現(xiàn)象。</p><p> 柴油發(fā)電機組配氣機構(gòu)各機件的技術(shù)狀況在工作過程中是不斷變化的，如氣門、氣門座和凸輪軸等主要機件，在高溫高壓和沖擊負(fù)荷的作用下，會產(chǎn)生機械磨損和化學(xué)腐蝕，這樣就破壞了氣門與座的密封性和配氣定時，從而使內(nèi)燃機功率下降以及燃油消耗量增加。下面關(guān)于柴油發(fā)電機組氣門的四個工作情況及條件大家需要了解下。 </p> <p> 1、柴油發(fā)電機組氣門受交變(應(yīng)力)的沖擊負(fù)荷作用(氣門頻繁在高溫下進(jìn)行沖擊性的打開和關(guān)閉，氣門和氣門座相互撞擊)。 </p> <p> 2、柴油發(fā)電機組氣門受高溫高壓燃?xì)鉀_刷和燃燒產(chǎn)物的腐蝕，熱應(yīng)力高。 </p> <p> 3、柴油發(fā)電機組氣門潤滑條件差。 </p> <p> 4、柴油發(fā)電機組氣門與氣門導(dǎo)管摩擦頻繁。柴油發(fā)電機組消聲器可以分為阻性消聲器、抗性消聲器、阻抗復(fù)合式消聲器、擴容減壓、小孔噴注式消聲器等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px"><p>柴油發(fā)電機氣門的檢驗包括外部檢驗、氣門頂邊緣厚度的測量、氣門頂及氣門桿彎曲的檢驗、氣門桿失圓度和錐形度的檢驗、氣門桿磨損量的測量等等。下面說說外部檢驗及氣門頂邊緣厚度的測量。<p>1、外部檢驗，進(jìn)排氣門接觸面的磨損及氣門頭部的偏磨等，均可通過一般檢視即可發(fā)現(xiàn)。<p>2、氣門頂邊緣厚度的測量，各種內(nèi)燃機氣門頂?shù)倪吘壓穸染坏眯∮?.5mm。正常的氣門頂厚度要求是：汽油機不小于1mm，柴油機不小于1.5mm。在生產(chǎn)廠或大修時，決不能使用不合要求的氣門，若在中、小修時，氣門頂厚度大于0.5mm可繼續(xù)使用。柴油發(fā)電機組抗性消聲器適用于消除中、低頻率噪聲或窄帶早聲。浙江天然氣發(fā)電機組價格</p><p style="text-indent:25px">靜音式發(fā)電機組電流不平衡的原因：系統(tǒng)單相負(fù)荷太大，如有容量巨大的單相負(fù)載現(xiàn)象。浙江柴油靜音發(fā)電機組</p><p> 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> 1、柴油機在怠速運轉(zhuǎn)時，響聲類似小錘敲擊，是有節(jié)奏的"嗒嗒嗒"聲，明顯而清晰。 </p> <p> 2、敲擊聲隨柴油機溫度的變化而變化，低溫條件下聲音比較明顯；溫度升高后，其響聲減弱或消失。 </p> <p> 3、當(dāng)突然提高轉(zhuǎn)速時，就發(fā)出"嘎嘎嘎"的連續(xù)金屬敲擊聲。如果多缸活塞敲缸，當(dāng)轉(zhuǎn)速升高后，響聲嘈雜而無序。浙江柴油靜音發(fā)電機組</p><p
