目前，国内水轮机转轮叶片修复仍采用手工补焊、人工打磨等检修手段，工人劳动环境恶劣，劳动强度大，且检修效率低，质量差。 |
| 10. | Cavitations in foreign hydraulic turbines appear in clear water condition , so its destructive extent is not far more serious than in yellow river in our country . stronger stiffness and more agility are required for special - purpose robot for hydraulic turbine repair used in our country , especially robot for polishing after weld . foreign robot for hydraulic turbine repair could not satisfy our working require , so we develop special - purpose robot system that is used to polish and weld repair cavitated flow path surfaces of hydraulic turbines on all locations
国外水电站的水轮机汽蚀是在清水条件下产生的，其破坏程度远不及我国黄河等水域严重，用于我国水轮机修复工作的专用机器人，特别是补焊后承担打磨的机器人，要求有更强的刚度和更大的灵活性，国外水轮机修复机器人满足不了我国水轮机修复工作要求，因此我们开发了用于在机坑内对水轮机空蚀磨损破坏表面进行修复的“水轮机修复专用机器人” 。 |
