杨凌水电站水轮机转轮汽蚀的堆焊处理

Puddle Welding Processing of Cavitation on Turbine Runner of Yangling Hydropower Station

通过采用堆焊技术对杨凌水电职能轴流式水轮机转轮气蚀进行了处理,明显提高了机组的出力,延长了转轮使用寿命,创造了较好的经济效益。

The paper introduces the puddle welding technology that is applied to remove the cavitation of axial-flow turbine of Yangling hydropower plant. After the puddle welding, the output is obviously improved, runner lifetime is prolonged and good economic benefits are achieved.
