摘要

本文介绍了阿尔斯通和hydro - quacimbec合作开发一种新的工厂机器人抛光工艺的结果。目标是通过将表面粗糙度降低到传统方法无法达到的水平来提高涡轮机效率。作为2010年7月至2011年3月的一个试点项目，位于索莱-特雷西的阿尔斯通制造工厂用这种新技术对hydro - quacimbec的Sarcelle电站的三个完整的轴流式涡轮机进行了抛光。表面光洁度从Ra = 15 μm降低到Ra = 0.1 μm，数控加工留下的波纹以5 h/m2的总体速度磨去。将表面粗糙度从标准IEC推荐的Ra=3 μm降低到Ra=0.1 μm，涡轮效率提高了0.5%。这种安全的新方法证明了它在提高表面处理质量、生产率和工人安全方面的巨大潜力。

Robotic polishing of turbine runners

This paper presents the results of a partnership between Alstom and Hydro-Québec for the development of a new factory robotic polishing process. The goal is to improve turbine efficiency by reducing surface roughness to a level that is unattainable with conventional methods. Three entire axial-flow turbines for Hydro-Québec's Sarcelle power station were polished with this new technique at the Alstom manufacturing plant in Sorel-Tracy as a pilot project between July 2010 and March 2011. The surface finish was lowered from Ra = 15 μm to Ra = 0.1 μm, and the waviness left by numerical control machining was grinded away at an overall rate of 5 h/m2. The reduction of surface roughness from the standard IEC recommendation of Ra=3 μm to Ra=0.1 μm resulted in a 0.5% increase in turbine efficiency. This safe, new method proves its great potential for enhanced surface finish quality, productivity and worker safety.
