| 8. | This paper analyzes the repairing feature on perforating casing and presents a new procedure that the root of perforating hole is covered by a little block age plate and then repair welding is carried out 通过对射孔枪管修复特点的分析,提出了先利用小堵板盖住射孔眼的根部,再进行补焊的新工艺,实现了枪管的重复利用,为油田同类产品的修复提供了宝贵经验。 |
| 9. | At present , the means for repairing hydraulic turbine blades in our country are still manual weld and manual polish . the working condition is bad and labour intensity great for workers and overhaul efficiency low and inferior 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” 。 |
