| 摘 要： | 2009年末,大唐碧口水力发电厂3号水轮发电机组在运行的一周内出现三次推力油槽油位下降的现象,给机组的正常运行构成了极大的威胁,同时也增加了大量的维护成本。经过对可能造成推力油槽油位下降多种原因进行分析论证,最终确认导致的推力油槽油位下降的原因为推力轴承油冷却器渗漏。在秋检时对3号机10台推力轴承油冷却器进行打压试验,发现4号油冷却器存在渗漏现象,将4号冷却器进行了整体更换后回装,机组运行至今再未发生推力油槽油位下降的现象。

| Abstract: | At the end of 2009,after a week operation of Datang Bikou Hydropower Plants No.3 hydro-generator unit,it emerges thrust oil tank oil level drops 3 times,which brings large threat for the normal operation of unit,and increase the cost of maintenance.The article analyzes the causes of thrust oil tank oil level drops is thrust bearing oil cooler leak.The bulge test is applied to thrust bearing oil cooler of No.3 unit,and it shows that No.4 oil cooler leaks.After replacing it as a unit,the operation of unit is normal and thrust oil tank oil level drop is not appeared again. |
