摘要
紫兰坝水电站机组已运行14年,水轮机的导水机构是由国外公司设计、制造,导水机构缺陷率逐年上升,因导水机构备件均为进口件,存在采购周期长且结构尺寸、技术参数等无法满足原设计要求等问题,导致电站目前无法正常采购导水机构备件,已严重影响紫兰坝公司的正常电力生产。针对紫兰坝水电站目前存在的导水机构备件全部依赖进口的采购和技术风险,紫兰坝公司联合东方电机有限公司开展了导水机构备件国产化替代设计研究,通过对原导水机构部件进行结构、材质、性能、装配等全面分析对比研究与国产化替代设计,实现了紫兰坝水电站导水机构备件采购自主可控和技术优良的目标,为我国类似电站的进口件国产化替代研究与应用提供借鉴。
Zilanba hydropower Station unit has been in operation for 14 years.The water deflection of the turbine is designed and manufactured by foreign companies,and the defect rate of the distributor increases year by year.As the spare parts of the water guide mechanism are imported,the procurement cycle is long and the structure size and technical parameters cannot meet the original design requirements.As a result,the power station cannot normally purchase the spare parts of the distributor at present,which has seriously affected the normal power production of Zilanba Company.In view of the procurement and technical risks of the existing distributor spare parts of Zilanba hydropower station,which all rely on imports,Zilanba Company and Dongfang Electric Machine Co.,LTD carried out a study on the replacement design of the distributor spare parts made in China.Through a comprehensive analysis,comparison and research on the structure,material,performance and assembly of the original distributor parts and the replacement design made in China,The objective of autonomous and controllable procurement of water guide mechanism spare parts of Zilanba hydropower station and excellent technology have been achieved,which will provide references for domestic substitution research and application of imported parts of similar power stations.
