高含沙对水轮机组的危害及对策

The harm of high sediment content flow to hydro-turbine and the counter-measures

混流式水轮机在高含沙水流中运行时，常遭受泥沙磨损和磨蚀的破坏。本文主要介绍作者在魏家堡水电站对混流式水轮机的易磨蚀部件进行修复、修型、改型等抗磨蚀措施方面的实践情况。通过综合治理，提高抗磨蚀性能。

When opration under high sediment flow condition, the turbine is often destroyed by abrasion and erosion of sediment. The practice of repairing of the turbine parts for Weijiapu hydropower station is introduced. The performance of anti abrasion of turbine can be improved by comprehensive measures.
