Abstract:During the localization of large power IE emergency diesel generator sets (EDG) in nuclear power plant, abnormal wear of injection pumps occurred several time.To explore the reasons for abnormal wear, fault tree of components manufacturing, cleanliness, lubrication, testing and relevant elements was established.The effect of roller material, testing lubrication, and the design of roller bore, etc. on abnormal wear was studied. In order to improve the safety and reliability of EDG commissioning and operation, some effective improvements were made based on the analysis. |
