1、華北電力大學(xué)（保定）碩士學(xué)位論文潮州發(fā)電公司600MW機(jī)組振動(dòng)原因分析及消除姓名：朱軍申請(qǐng)學(xué)位級(jí)別：碩士專業(yè)：動(dòng)力工程指導(dǎo)教師：安連鎖劉石20090426華北電力大學(xué)工程碩士學(xué)位論文摘要摘要本文介紹了潮州電廠600MW機(jī)組的特點(diǎn)，總結(jié)和分析了汽輪發(fā)電機(jī)組故障診斷的內(nèi)容和機(jī)理，并針對(duì)現(xiàn)場(chǎng)解決機(jī)組振動(dòng)問(wèn)題采取的動(dòng)平衡實(shí)施方法進(jìn)行了分析，闡述了機(jī)組檢修工藝對(duì)振動(dòng)的影響，分析了轉(zhuǎn)子中心、標(biāo)高等參數(shù)與振動(dòng)的關(guān)系，分析了振動(dòng)與潤(rùn)滑油溫、真空、軸封溫

2、度、機(jī)組真空、排氣缸溫度等運(yùn)行參數(shù)的關(guān)系以及無(wú)功、有功負(fù)荷對(duì)振動(dòng)的影響。對(duì)影響機(jī)組啟動(dòng)過(guò)程中振動(dòng)的運(yùn)行參數(shù)進(jìn)行了分析研究。對(duì)于機(jī)組檢修后出現(xiàn)的異常振動(dòng)著重進(jìn)行了分析研究，通過(guò)現(xiàn)場(chǎng)全息動(dòng)平衡方法將各瓦軸振降至合格范圍內(nèi)，合理解決了潮州電廠600MW機(jī)組的振動(dòng)問(wèn)題。關(guān)鍵詞：汽輪發(fā)電機(jī)組；振動(dòng)；動(dòng)平衡ABSTRACTItintroducedthefeatureofChaozhouPowerPlantinthispapersummarizeda
