洛古电站大坝廊道排水泵改造探讨

Research on the Transforming for Corridor Row Pump of Luogu Dam

洛古电站大坝廊道排水系统设计采用两台自吸泵互为备用进行工作,自安装投运以来常常发生水淹廊道,影响着大坝的安全生产运行。针对存在问题,通过技术分析,决定用潜水泵替代自吸泵进行改造。通过排水泵选型、改造方案确定、施工技术安全方案对原自吸排水泵进行了改造,提高廊道排水泵的工作可靠性,使洛古大坝廊道排水系统实现无人值班的运行方式。

Two self-priming pumps are used to work for mutual backup in the corridor drainage system of Luogu dam. The corridor of dam usually is flooded since the pumps have been installed, and the safety of dam has been in danger. To solve the problem, after an analysis and discussion from the experts of company, the director decides to replace the self-priming pumps by submersible pumps. By using the submersible pumps, the work reliability of corridor drainage pump has been improved obviously; the ＂unattended＂ operation mode of Luogu dam corridor drainage system also has been realized.
