柴油發(fā)電機組曲柄連桿機構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。比如說，活塞環(huán)的敲擊聲是鈍啞的"啪啪"聲。響聲的變化特點是隨轉(zhuǎn)速升高而隨之增大，并且變成較雜亂的聲音。那么是什么原因?qū)е掳l(fā)電機活塞環(huán)響呢？ </p> <p> 原因一：柴油發(fā)電機組活塞環(huán)斷裂。 </p> <p> 原因二：柴油發(fā)電機組活塞環(huán)槽積炭過多或環(huán)的端隙過小，當溫度升高后沒有膨脹的余地，使活塞環(huán)卡死在氣缸內(nèi)或環(huán)槽內(nèi)。 </p> <p> 原因三：柴油發(fā)電機組活塞環(huán)與環(huán)槽磨損嚴重，側隙、背隙和端隙過大。 </p> <p> 原因四：氣缸磨損后，在氣缸上口形成凸肩(俗稱缸肩)，若修理不規(guī)范，活塞上移使活塞環(huán)與缸肩相碰，出現(xiàn)異常聲音。廣東2500kw發(fā)電機靜音式發(fā)電機組電流不平衡的原因：系統(tǒng)單相負荷太大，如有容量巨大的單相負載現(xiàn)象。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">汽車用發(fā)電機可分為直流發(fā)電機和交流發(fā)電機，由于交流發(fā)電機在許多方面優(yōu)于直流發(fā)電機，直流發(fā)電機已被淘汰，目前所有汽車均采用交流發(fā)電機，那么交流發(fā)電機怎么工作的呢？汽車發(fā)電機同樣基于電磁感應原理。當外電路通過電刷使勵磁繞組通電產(chǎn)生磁場，當轉(zhuǎn)子旋轉(zhuǎn)時，磁通交替地在定子繞組中變化，根據(jù)電磁感應原理可知，定子的三相繞組中便產(chǎn)生交變的感應電動勢。定子繞組若接入用電負載，電機就有交流電能輸出，經(jīng)過發(fā)電機內(nèi)部的整流橋?qū)⒔涣麟娹D(zhuǎn)換成直流電從輸出端子輸出。這就是汽車交流發(fā)電機的發(fā)電原理。</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：柴油的標號不符合標準，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。隨著工業(yè)的不斷發(fā)展，柴油發(fā)電機組普遍應用于醫(yī)院、養(yǎng)殖、房地產(chǎn)、工地等各種行業(yè)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

柴油發(fā)電機組活塞敲缸會導致柴油機燃油和機油消耗量增加，竄機油。當活塞敲缸嚴重時，還會打碎活塞，敲壞氣缸，甚至使連桿斷裂，打壞缸體。那么發(fā)電機活塞敲缸響的原因是什么？ </p> <p> 1、活塞與氣缸壁配合間隙過大。 </p> <p> 2、氣缸套、活塞及活塞環(huán)的質(zhì)量較差，潤滑不良，柴油機運行一段時間后，使氣缸與活塞的磨損嚴重，活塞和氣缸的間隙增大，同時在氣缸套對應初道氣環(huán)略上位置處出現(xiàn)較嚴重的臺階(俗稱缸肩)，使活塞敲擊氣缸發(fā)出異響聲。 </p> <p> 3、活塞裙部與氣缸磨損嚴重，造成失圓而敲缸。 </p> <p> 4、活塞受熱變形，由于不規(guī)則磨損形成的圓度和圓柱度誤差超過規(guī)定。 </p> <p> 5、連桿彎曲或扭曲變形等使活塞在氣缸內(nèi)偏斜不正，造成不正常磨損，使活塞敲擊。 </p> <p> 6、連桿軸瓦與連桿軸頸或活塞銷與連桿襯套配合過緊。柴油發(fā)電機組抗性消聲器是利用聲波的反射、干涉及共振等原理，吸收或阻礙聲能向外傳播。安徽學校用柴油發(fā)電機</p><p
