The article deals with the method of evaluating oil equipment remaining lifetime by vibration diagnostics. The advantages of machine maintenance according to its technical condition, compared with planned-preventive repairs, are given. The technical conditions of the wellhead stuffing box of a beam pumping unit and a centrifugal pump machine were studied by Corsair vibration analyzer and Aurora software product, providing the evaluation of the current machine condition for planning a repair period. While analyzing the results of the equipment vibration diagnostics, the conclusions on faults were made and the dates of predictive maintenance were determined: the date for the next measurement (condition control) and the date for repair. The vibration diagnostics significance was confirmed in experiments as the most universal parameter which provides accurate information on equipment condition, making it possible to evaluate equipment technical condition in operation and predict its reliability.

Application of vibration diagnostics methods and programs to assess the remaining lifetime of oil equipment
