| 中文摘要: |
| 界牌电站2#机组改造过程中在水导瓦安装就位后发现其中心与轴颈中心出现向上游偏离的情况，通过对各部件尺寸的检查，确定是旧管形座内壳体轴向尺寸与设计图纸尺寸制造时存在偏差的原因导致.2#机组改造过程中采用安装优化处理，在转轮室上游法兰面增加钢垫板给予机组轴向尺寸补偿，消除了设备装配中存在的缺陷，达到了改造增效的目的，取得了成功. |
| 英文摘要: |
| The transformation of the center and the journal center in the process of the installation of the water guide tile in the process of transformation of the 2 # unit of the sector power station，by checking the size of each component，it was determined that there is a deviation from the design of the size of the inner shell of the old pipe seat and the size of the design sheet.Installation optimization was used in the transformation process of 2 # unit，increasing the steel plate on the flange side of the wheel chamber gives the unit axial dimension compensation，eliminating the defects in the equipment assembly，to achieve the purpose of transformation efficiency，and achieved success. |
