【摘要】：针对江边水电站技术供水系统设备在汛期严重堵塞、影响机组安全稳定运行的问题,提出了循环冷却供水系统的改造方案。在改造过程中,结合电站实际情况,在仔细斟酌、就地取材的基础上,充分利用现有的设备和条件,降低工程造价,对系统实施优化。优化改造后,通过现场实测了解到,该系统运行良好,可靠性更高,且改善了机组水导轴瓦、发电机上导和下导以及发电机空冷器的温升,从而延长了设备的使用寿命,节约了检修维护费用。通过该工程案例的应用,说明循环冷却供水方案亦适合大中型地下厂房式水电站。
[Abstract]:In view of the serious blockage of the technical water supply system equipment of Jiangbian Hydropower Station in flood season, which affects the safe and stable operation of the unit, the retrofit scheme of the circulating cooling water supply system is put forward. In the process of renovation, the actual situation of the power station is combined. On the basis of careful consideration and local selection of materials, the existing equipment and conditions are fully utilized, the project cost is reduced, and the system is optimized. After optimization and transformation, it is found that the system is running well through the field measurement. Higher reliability and improved unit water guide bearing, generator upper and lower guide and generator air cooler temperature rise, thus prolonging the service life of the equipment. The cost of maintenance and repair is saved. Through the application of this project, it is proved that the water supply scheme of circulating cooling is also suitable for large and medium-sized underground powerhouse type hydropower stations.
