柴油發(fā)電機(jī)組活塞環(huán)在長(zhǎng)期的使用過程中受到高溫高壓和往復(fù)運(yùn)動(dòng)的影響，會(huì)使磨損加劇。當(dāng)磨損達(dá)到一定限度時(shí)，湖北工業(yè)燃?xì)獍l(fā)電機(jī)，活塞環(huán)的彈力開始減退，端隙、側(cè)隙和背隙也會(huì)逐漸增大，對(duì)燃燒室的密封作用會(huì)減弱。 </p> <p> 一、柴油機(jī)運(yùn)行時(shí)，打開加機(jī)油口蓋觀察冒yan情況，若有冒yan現(xiàn)象，則逐缸斷油，若發(fā)現(xiàn)冒yan減輕或消失，響聲也消失，則說明是活塞環(huán)槽磨損過甚或活塞環(huán)斷裂，應(yīng)及時(shí)維修。 </p> <p> 二、若斷油試驗(yàn)響聲沒有變化，而用一字旋具抵著缸蓋部位，感覺有明顯的振動(dòng)，則是活塞環(huán)碰撞氣缸磨損處的缸肩而發(fā)出的響聲。此時(shí)應(yīng)重新修整氣缸，以免活塞環(huán)斷裂，湖北工業(yè)燃?xì)獍l(fā)電機(jī)。 </p> <p> 三、在熱機(jī)檢查時(shí)，可從噴油器安裝口處注入少量機(jī)油，轉(zhuǎn)動(dòng)曲軸，再裝回噴油器發(fā)動(dòng)柴油機(jī)，若短時(shí)間內(nèi)響聲減弱或消失，則是活塞環(huán)與氣缸壁密封不良。若注入機(jī)油后，仍從加機(jī)油口冒yan或更甚，則可確診為活塞環(huán)對(duì)口(各道活塞環(huán)的開口間隙安裝在同一方向上，安裝時(shí)，相鄰兩活塞環(huán)的開口間隙應(yīng)錯(cuò)開120度-180度)或活塞環(huán)卡在環(huán)槽內(nèi)失去彈性，湖北工業(yè)燃?xì)獍l(fā)電機(jī)，對(duì)此應(yīng)進(jìn)行維護(hù)，徹底去除積炭。

連桿軸承是柴油發(fā)電機(jī)中必不可少的配件，它可以支撐整個(gè)機(jī)組的機(jī)械旋轉(zhuǎn)，減少發(fā)電機(jī)組的摩擦帶來的傷害。然而，用戶在使用機(jī)組過程中，突然加速時(shí)，有時(shí)候會(huì)聽到"噹噹噹"的響聲，當(dāng)轉(zhuǎn)速和負(fù)荷增大時(shí)，響聲也增大。遇到這種情況的時(shí)候，如何診斷與處理呢？ </p> <p> 1、查看機(jī)油表壓力，若過低并伴隨有"噹噹噹"的聲音，則應(yīng)進(jìn)一步檢查。 </p> <p> 2、將加機(jī)油口蓋打開，有聽診器時(shí)將聽診器插入加機(jī)油口內(nèi)，可聽到敲擊聲，嚴(yán)重時(shí)在柴油機(jī)附近便可聽清，當(dāng)突然加速時(shí)，響聲更為突出。 </p> <p> 3、將柴油機(jī)轉(zhuǎn)速稍提高，避開怠速工作時(shí)的粗暴聲，逐缸斷油細(xì)聽，若斷油后的聲音減輕，再迅速供油的瞬間發(fā)出"噹"的響聲，則說明該缸連桿軸承響。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
