2011年11月东坪水电厂机组检修时发现3号机组转轮室里衬空蚀严重,为彻底消除空蚀隐患,决定采取更换转轮室的方式进行处理。受工期和检修费用的约束,转轮室更换只有采取不拆卸转轮,而将新、旧转轮室下半部旋转180°的吊装新工艺和新方法,并在该厂3号机组转轮室改造更换工作中成功实施。灯泡贯流式机组下部转轮室180°旋转吊装新工艺属五凌公司在灯泡贯流式机组不拆卸转轮前提下的首创,为国内灯泡贯流式机组更换转轮室提供了新的技术参考。
In November 2011, during the overhaul of the unit of Dongping Hydropower Plant, it was found that the cavitation of lining of the runner room of No. 3 unit was serious. In order to completely eliminate cavitation damage, it was decided to take the way of replacing the runner room. Subject to the construction period and overhauling costs, the only change to the runner room is to take the new technology and new method of hoisting the lower half of the new and the old runner room without dismantling the runner, and at the No.3 unit runner of the plant Room transformation and replacement work successfully implemented. Bulb tubular turbine unit under the lower part of the rotation of 180 ° rotary hoisting process is a new company in Ling Ling Bulb turbine unit is not demolished under the premise of the premise for the domestic Bulb turbine unit to replace the runner room provides a new technology reference.
