The cavitation of flow-passing parts of hydro turbines in Baozhusi Hydropower Station are summarized, and on this basis, the treatment and prevention measures for controlling caviation of turbines which running in a cleaner river are proposed herein. The practices show that these measures can effectively improve the operation of turbine and be as reference for treating and preventing cavitation of similar turbines.%在检查、分析宝珠寺水电站水轮机过流部件数年来的空蚀情况的基础上,探索出了一些处理和预防在水质较清洁河流中运行的水轮机空蚀的有效方法,使其水轮机的运行状况得到持续的改善.这些方法可供同类型水电站水轮机空蚀的处理和预防借鉴.
