Construction and application of hydraulic machinery R&D platform

中国水科院水力机械研发平台是以建设水力机械新模型试验台为核心,结合CFD数值模拟技术的开发和应用,利用现代计算机技术和测试技术搭建的研究开发平台。该平台的建设在同台对比试验、贯流式水轮机力矩测试、浑水浓度及水头测量、固液两相流CFD数值模拟及磨损预估等方面提出了创新的方法及技术,使试验台试验能力和测试精度均达国际领先水平。通过该平台,开发和设计出一大批优秀的水力机械模型转轮、抗磨材料和稳定性技术,广泛应用于水利、水电的建设与改造中,并进行了三峡右岸、溪洛渡、向家坝等巨型水电站的水轮机及江苏溧阳抽水蓄能电站、浙江仙居抽水蓄能电站的水泵水轮机同台对比试验,为锦屏一级水电站、土耳其OBRUK水电站、老挝南立水电站等国内外十几个大、中型水电站的水轮机和水泵水轮机进行了模型验收,推动了水轮机、水泵水轮机性能水平的提高和水力机械模型测试技术的进步。

The research and development platform for hydraulic machinery of IWHR is built based on the construction of a new model test stands of hydraulic machinery,combined with the development and application of CFD numerical simulation technology,and using modern computer technology&testing technology.During the construction of the platform,innovative methods and techniques were proposed in such areas as comparative test,torque test of tubular turbine,measurement of sediment water concentration and net head,CFD numerical simulation and abrasion prediction of solid-liquid two-phase flow,so that the test function and testing precision of the test stands have reached the international leading level.With this platform,a large number of outstanding hydraulic machinery model runners,anti-wear materials and operating stability technology have been developed and designed,which are widely used in the construction and renovation of water and hydropower project.The comparative tests among the turbines in super hydropower station such as Three Gorges Right Bank,Xiluodu,Xiangjiaba,and the pump-turbines in Jiangsu Liyang and Zhejiang Xianju pumped storage power station were carried out on the test rig.Additionally,model acceptance tests of turbines and pump turbines for more than a dozen of large and medium-sized hydropower stations in china and abroad such as Jinping first stage hydropower station,Turkish OBRUK Hydropower station,and NAM-LIK hydropower station in Laos are completed on this test rig.This research project has promoted the improvement of the performance level of hydraulic turbines,pump-turbines and the progress of hydraulic machinery model testing technology.
