中小型水电站水轮机安装的重点和难点是锥管、座环和蜗壳安装的质量控制,安装偏差直接影响到水轮机组轴线的误差。安装质量控制方法多种多样,本文从实际应用的角度,介绍了一种比较实用的安装质量控制方法,经实践证明,安装质量完全满足设计要求。
The key and difficult point of the turbine installation in small and medium-sized hydropower stations is the quality control of the conical pipe, seat ring and volute installation, and the installation deviation directly affects the error of the turbine unit axis. Installation quality control methods vary, this paper from a practical application point of view, introduced a more practical method of installation quality control, the practice has proved that the quality of the installation to fully meet the design requirements.
