Abrasion analysis for Gezhouba hydroturbines

The Gezhouba bydropower plant as the first one on Yangtze river has caused attention of engineers inside the country to the conditions of its turbines abrasion. According to the features of sedimentation in Yangtze river, the test results of sediments at Gezhouba project, the observations during the ten year's operation and the conditions of the turbine's operation and its repairs, the our rent abrasion of Gezhouba project turbines have been evaluated and analysed. Finally, nine recommendations were proposed in this article for the future evaluation and solution of Gezhouba project turbine abrasion.
