摘要
白莲河水电厂2号机组运行时发生了剧烈振动,导致推力油盆回油管道断裂。相关分析发现,水轮发电机组的推力头和镜板质量存在较大问题,不能保证正常运行。进而,对这些缺陷进行了修复处理,同时找出了机组存在的其他缺陷。此后,改进了安装工艺,经精心安装调试,解决了该机组不稳定运行近三年的问题。
Heavy vibration occurred during operation in the No.2 hydropower generating unit in Bailianhe Hydropower Station,which even caused the fracture of the oil-return pipeline of the thrust oil basin.The relevant analysis shows that obvious quality problems are found from both the thrust block and mirror plate and then the normal operation cannot be ensured.Furthermore,those defects are repaired and restored,simultaneously,some other faults are also found from the unit.After that,the relevant installation technology is improved and the problems from the unstable operation of the unit for nearly three years are solved through careful installation and commissioning concerned.
