飞来峡电厂开停机过程中技术供水中断原因分析

Analysis on Interruption Causes of Cooling Water During Startup and Shutdown of Feilaixia Hydropower Plant

分析飞来峡电厂机组开停机过程中出现技术供水中断的原因,系机组流道技术供水取水管网积存的大量积气,造成生活供水泵、机组冷却水外循环泵和消防水泵等离心泵技术供水中断所致,并对解决此故障的改造方案进行介绍。

The interruption of cooling water during startup and shutdown of Feilaixia hydropower plant is resulting from the cooling water interruption of centrifugal pumps, such as living water pump, external circulating pump for unit cooling water and fire water pump etc., caused by a large amount of air accumulated in cooling water intake pipe network of unit flow passage. The solution for the above problem is introduced in the paper.
