摘　　要：国产引进型600MW汽轮机由单阀切换为顺序阀投运行时出现了很多问题,例如,瓦温偏高,瓦振、轴振超标等,严重影响了机组的安全运行。为此国内的很多厂家进行了大量实验,对于顺序阀的改造方式也不尽相同。调查分析了对于此现象的研究机理,比较了部分电厂的顺序阀投运方案,调查分析的结果对于同类机组的改进有很好的参考价值。There are several problems while the imported-type 600MW steam turbine switched over the single valve to the sequence valve. The temperature of the shaft tile is too high ; the shake of the tile and the axle are over limitation, etc. All the problems influence severely on the operation of the units. Therefore a lot of theoretical and experimental studies have been have carried out by several institutes and manufacturers, and different technical innovations have been applied. This paper investigated the researches resuhs and compared the effects of technical innovation . The result has great referenced value for the improvement of the similar unit.
