1、汽轮机油系统水分超标的危害
油系统中带水对汽轮机的安全运行有相当大的危害，当空气中和汽轮机内的水蒸汽进入润滑油系统后凝结成水，当油和水混合在一起后，再被搅动油即被乳化，而透平油被乳化后能使调节系统中套筒及滑阀等部件严重锈蚀，造成滑阀卡涩，降低系统灵敏度，加重机组运行负荷。
同时，还会造成轴承和轴颈的磨损，引起调节系统和保安装置动作失灵或误动，严重时会导致机组超速甚至飞车。如果乳化液沉积于油循环系统中，就会妨碍油的循环，影响散热，造成供油不足，容易导致轴承烧瓦。汽轮机油乳化使汽轮机油的氧化加速，酸值升高，产生较多的氧化沉积物，从而进一步延迟了汽轮机油的破乳化时间，造成恶性循环。
2、防范汽轮机油系统进水的措施
为了避免油带水这种情况的发生，可在原有一台滤油机的基础可上增设了一台滤油机，并改进油净化系统管道。同时可采取以下改进措施:
1）针对轴封系统结构问题，在大修期间对轴封间隙做了合理调整，减少了轴封漏汽。
2）在变负荷工况下，加强了对轴封供汽压力的监调。
3）保持冷油器油压大于水压，启停循环水泵时，严格执行操作规范，避免冷却水压瞬间升高造成冷油器内部损坏，而导致油中进水。在机组运行中还应进行冷油器放水放油检查，发现冷油器泄露，应及时判断原因，确定异常设备后，尽快进行冷油器的切换，隔离工作。
4）加强对主油箱系统排烟风机的运行调整，保持轴承箱在一定的微负压下运行，防止负压过大导致油中进水。
5）加强了运行中对主油箱定期放水以及化学油质抽测工作。
6）当发现油系统中已经进水，油中进水后，要及时采取过滤及排污的方法，最大限度排除水分，还要防止金属表面锈蚀。
