那多电站机组润滑系统技术改造

Unit lubricating system upgrade for Naduo Hydropower Station

那多电站试机3#机组发生烧瓦事故,业主组织技术攻关,对机组润滑系统进行技术改造,将外电源、外循环式润滑系统改造为主轴动力直接循环润滑系统,彻底消除了安全隐患,运行效果良好。

After bush-burning accident occurred during the trial operation of No. 3 turbine generator unit of Naduo hydropower station, the enduser had upgraded the unit lubrication system from an external circulation lubricating system in need of exterior power supply to a main shaft drive direct circulation system, which removes the hidden danger and yields good operation effect.
