Diagnostics and repair of centrifugal oil transfer pump rotor shaft

[摘要] Materials on methods for diagnostics and repair of centrifugal oil transfer pump rotor shaft are considered. Results of research on reconditioning worn-out pump shaft journals are presented with provision of surface low roughness by a method of mechanical and ultrasound surface ruggedizing final finish. Analysis of the results attained by the ultrasound ruggedizing finish of a pump shaft and inspection of the superficial layer quality has shown the method, when applied, to considerably increase equipment availability, reliability, and serviceability.
