摘要
灯泡贯流式机组,具有适用水头低、过流量大以及效率高,机组安装开挖小,建设投资少等特点,广泛用于开发低水头水力资源。但由于机组转动惯量小,稳定性差,相应水轮机水力振动对其影响也较大。文章结合青海高海拔地区灯泡贯流式水轮机组运行情况,对振动原因进行了分析。
Bulb tubular units possess several characters such as low water head applied, huge flow rate, high efficiency, small installation dig and construction investment, therefore it＇s broadly applied in low water head hydraulic station. But because of smart rotating inertia of units and tack of stabitity, thus hydrautic vibration induces huge effect. The paper makes analysis on vibration reason combining with operating situation of tubular units on High altitude areas of Qinghai province.
