华安水电厂一号机组技术改造的探索与实践

Exploration and Practice of Technical Transformation of No.1 Generating-unit in Huaan Hydropower Station

通过对华安水电厂一号机组进行增容改造,解决了过流部件磨损、主轴密封不可靠漏水、主轴中心补气口漏水等问题。结合华安水电厂一号机组技术改造中出现的问题及相应的解决措施,系统阐述水电机组改造的关键技术与注意事项,为今后相关工程项目提供借鉴和参考。

Through the capacity expansion of No.1 generating-unit in Huaan hydropower plant, the flow passage wear, the unreliable leakage of main-shaft sealing, the leakage of main-spindle center air admission inlet and other prob- lems were solved. Combination appeared problems when No. 1 generating-unit of Huaan Hydropower Station was technically transformed and corresponding solutions, key technologies and matters needing attention of hydropower generator units transformation were formulated, which will provide the reference for the future related projects.
