大凡建于多泥沙河流上的水电站,特别是径流式电站,都面临着水下部分严重磨损的问题。这里整理出一些研究资料,对于改进水轮机及水下部分合理的水力设计,以及发展理想的冶金用材,将是必要的,同时也会有助于进行检修工作。检修应确保尽量减少继续磨损,使磨损量控制在最小。这篇文 Most of the hydropower stations built on multi-silt rivers, especially run-of-river power stations, all face the problem of serious underwater parts wear. Some research materials are collated here and will be necessary to improve the rational hydraulic design of the turbine and submarine and to develop the ideal metallurgical materials, and it will also be helpful for overhaul work. Maintenance should ensure that minimize wear and tear to minimize wear and tear. This article
