The present-day production and repair of vessels imply saving costs and retaining output quality. One of the cost items is maintenance of processing equipment of manufacturing plants with minimal expense. It can be implemented using up-to-date engineering diagnostics. Suggested tool equipment of vibration diagnostics and vibration adjustment allow not only controlling true technical state of electrical machine, but bring vibration level to target values. The set of methods, including RMS level vibration measuring, narrow-band frequency analysis and spectrum of envelope of vibration, provide insight into complete idea of true technical state of rotor equipment. Vibration adjustment methods, such as alignment, frame flatness setting-out, frame hardening, allow successfully to perform the balancing procedures. The article presents the symptoms of the most widespread defects of rotary converters, which are affected to perform mechanism balancing. Methods of successive elimination of revealed defects are described in detail by the example of converter vibration adjustment. According to the analysis results, application of methods and facilities of vibration diagnostics and vibration adjustment allow to significantly increase repair intervals and, as a consequence, to decrease costs of motor-operated mechanism repair.
