| Summary: | In order to solve the vibration problem of the AC lubricating oil pumps for the feed water pump driving turbine and ensure the safe operation of the unit, the method of numerical calculation combined with on-site vibration testing and analysis is adopted to diagnose the cause of the fault, then design a reasonable reinforcement scheme and eventually solve the vibration fault problem. The results show that the resonance caused by the weak vertical integral stiffness of the supporting oil tank roof and the uneven deformation of the roof from the tilt of the pump foot are the major reasons contributing to the large vibrations of the AC lubricating oil pumps. |
