摘要
利用数学模型 ,对白莲崖水电站引水系统过渡过程进行了计算 分别分析了不同的气室初始水位及气室横断面积对引水系统水力特性的影响 ,表明气室初始水位对管道压力有较大的影响 ,水位越低 ,其缓解压力波传播的作用越明显 ;增加气室横断面积 。
Utilizing mathematical model,this paper makes a numerical calculation of Bailianya hydroelectric station water-diverting structure transition process.By analysing different initial water level and cross sectional area of air chamber influence on hydraulic characteristics of water-diverting structure,it shows initial water level of air chamber obvious influence on pipeline pressure,the lower initial water level,the bigger action of lysis pressure wave transmission;adding cross sectional area of air chamber,the action of reducing maximum fluctuation amplitude is bigger than the action of flow stability.
