摘　　要：针对大型立式轴流泵站存在的典型故障,调查统计了5座立式轴流泵站。根据故障资料,对泵站主机组、辅机系统及断流设施进行案例分析,得出系统发生故障的主要部位及其主要原因。从泵轴及轴承故障、叶轮及导叶体磨损故障、叶调机构故障、电机定子短路故障、断流设施故障、主变及站变故障6个方面给出故障预防策略和防治措施。分析结果可为管理人员提供快速找到对应的故障处理方法,提高泵站智能化管理效率。Aiming at the typical faults of large vertical axial flow pumping station,five vertical axial flow pumping stations are investigated and counted in this paper.According to the fault data,the main unit,auxiliary system and cut-off system of the pumping station are analyzed and case studies are carried out.The main parts of the three systems and the main causes of the faults are obtained.Typical fault prevention strategies and preventive measures are given from six aspects:pump shaft and bearing fault,impeller and guide vane wear fault,blade regulating mechanism fault,motor stator short circuit fault,cut-off facility fault,main transformer and station transformer fault.The analysis results can quickly find the corresponding fault handling methods for the operation and maintenance personnel and improve the intelligent management efficiency of the pumping station.
