溪洛渡深孔弧门充压水封运用预控措施研究

摘要

溪洛渡深孔弧门采用常规预压缩水封和充压水封两套水封止水.深孔充压水封在充分吸取其他工程成功经验的基础上,分别考虑设计和选型、安装调试、运行管理3个阶段,提前制定了符合自身特点的预控措施.目前,充压水封处于初期投运阶段,前两阶段取得了良好的效果.后续运行过程中,还将重点关注控制程序是否适应各种工况,不断完善系统的工作性能.%The conventional pre-compressed water seal and the pressurized water seal are simultaneously used in water sealing of bottom outlet radial gates in Xiluodu Hydropower Station.The pre-control measures for pressurized water seals are specially developed in advance for three stages of design and type selection,installation and commissioning,as well as operation and management after learning lessons from other hydropower projects.Currently,the pressurized water seals are commissioning and achieve good results.In following operation,it is focused on the control program whether adapting various operating conditions and to improve system performance continuously.
