Abstract The researches previously accomplished have been focused on design analysis, performance comparison and improvement of hydrocyclones for general applications and comprehensive results have been achieved. For the present research, an open loop experiment setup has been developed to study the feasibility of hydrocyclone separator as a pre-filtering device for sediment laden hydraulic turbine. The experimental setup for this study is designed primarily to investigate the effectiveness of hydrocyclone for high sediment period of turbine operation and consequent effect on turbine efficiency. The experimental analysis is designed to develop a general concept for operation of hydrocyclone in RoR hydro power projects. The results of the analysis showed that hydro cyclone separator is efficient in separating sediment particles of sizes as low as 45 μm. The analysis of separator at different position downstream from the intake has shown minimal effect on pressure drop but loss in discharge is comparatively visible with increased inlet head. The technical challenges like loss in efficiency and power output, turbine repair cost, turbine overhaul period can be mitigated. The future works for this study can be financial comparison of loss in power due to sediment erosion to use of hydrocyclone separator in hydraulic turbine working model.

载沙微型水力弗朗西斯水轮机研发试验研究

摘要 以往的研究主要集中在一般应用的水力旋流器的设计分析、性能比较和改进方面，取得了综合性的成果。对于目前的研究，已经开发了一个开环实验装置来研究水力旋流分离器作为载泥水轮机预过滤装置的可行性。本研究的实验装置主要是为了研究水力旋流器在涡轮机运行的高沉积期的有效性以及对涡轮机效率的影响。实验分析旨在为 RoR 水电项目中的水力旋流器操作开发一个一般概念。分析结果表明，水力旋流分离器可有效分离尺寸低至 45 μm 的沉积物颗粒。对进口下游不同位置的分离器的分析表明，对压降的影响很小，但随着进口水头的增加，排放损失相对明显。可以减轻效率和功率输出损失、涡轮机维修成本、涡轮机大修周期等技术挑战。这项研究的未来工作可以是在水轮机工作模型中使用水力旋流分离器因泥沙侵蚀造成的功率损失的财务比较。可以减轻效率和功率输出损失、涡轮机维修成本、涡轮机大修周期等技术挑战。这项研究的未来工作可以是在水轮机工作模型中使用水力旋流分离器因泥沙侵蚀造成的功率损失的财务比较。可以减轻效率和功率输出损失、涡轮机维修成本、涡轮机大修周期等技术挑战。这项研究的未来工作可以是在水轮机工作模型中使用水力旋流分离器因泥沙侵蚀造成的功率损失的财务比较。
