With regard to the growing of vibration value of high pressure liquid ammonia pump in urea plant,the advanced frequency spectrum technology was used to diagnose the defects on the pump body.Analyzed the failure reason after disassemble and detection,some measures were taken to eliminate the vibration failure successfully,such as changing the rotator and the main oil pump wabbler,modifying the oil seal vibration detection ring,which ensured the safe,stable and long term operation of the plant.
