【摘要】 本文通过对混流式转轮固有频率的对比分析,找出了影响混流式转轮固有频率的因素,使转轮在水中的固有频率同时避开转频与叶片个数的乘积和转频与导叶个数的乘积,保证混流式水轮机的安全运行。更多还原

【Abstract】 In this paper,according to different type of structure about Francis turbine,the natural frequency is researched and the factor to influence the natural frequency of Francis turbine is found.The natural frequency of runner in water must be avoided the value that the product of basic frequency for hydraulic generator set and number of blade or the basic frequency for hydraulic generator set and number of wicket gate to ensure operating of hydraulic generator set in safety.更多还原
