From many factors, the reliable operation of a centrifugal pump unit largely depends on the reliability of the electric motor, which is the main link of the centrifugal pump unit and an important factor in the failure-free operation of the centrifugal pump unit, which depends on the reliability of rolling bearings. This article is devoted to the study of the methodology for predicting vibration emissions and the transition of the technical state of a centrifugal pump unit to the states “Requires action” and “Unacceptable". Experimentally tested and confirmed the operability of the method for isolating vibration emissions in the flow of measuring the vibration of a centrifugal pump unit, separating a smooth increase in vibration from its emission. The technique for detecting and controlling the process of staged accumulation of damage and failure of parts by increasing the amplitudes of vibration emissions has been tested, which provides long-term and prompt proactive diagnostics throughout the entire period of operation, and the performance of the proposed diagnostic method has been confirmed.

The development of new methods of technical diagnostics is an important task aimed at improving the efficiency and safety of the operation of industrial equipment. Such methods are complexes of jointly used methods for obtaining diagnostic information, methods for extracting from it the actual data on the technical state of the diagnosed objects, and methods for organizing diagnostic processes. At the same time, the criteria of importance and value, as a rule, are different for the developers of these methods, developers of diagnostic systems, and direct operators of equipment, which requires the search for solutions that are a compromise for all interested parties and meet certain optimality requirements. One of the new approaches in the field of identifying and controlling new diagnostic information is the entropy method for evaluating data. Testing the applicability of this approach to the analysis of signals of vibration and partial discharges has shown the possibility of obtaining data on changes in the state of the diagnosed object. This information can be used to develop new diagnostic features designed for earlier detection of developing defects, as well as for checking and confirming technical diagnoses obtained by classical methods.
