摘　　要：导水机构起到将蜗壳中水流导入转轮,以活动导叶的角度变化使水能利用最优化的作用。阳蓄电站机组为400MW的混流式水泵水轮机机组,在水轮机机组安装过程中,导水机构采用无预装,即一次性安装到位的工艺。介绍了阳蓄电站水泵水轮机在埋件部分完成后进行导水机构安装的方法、质量把控措施、机组中心测定以及在安装水轮机时遇到的问题和解决问题的方式。The water guide mechanism guides the water flow in the volute into the runner to optimize the utilization of water energy with the change of the angle of the movable guide vane. The mixed-flow pump turbine unit with 400 MW unit in Yang Battery Station adopts the process of no pre-assembly, i.e. one-time installation in place, during the installation of the turbine unit. This paper describes the installation method of water guide mechanism, quality control measures, unit center determination, problems encountered during installation of water turbine in Yangyang Power Station and the ways to solve them after the buried parts are completed.
