Abstract: Research of vibration parameters generated during operation of the centrifugal pump, allowing to classify defects on the equipment base groups depending on the degree of damage and danger. This defects corresponds to a total of more than a diagnostic features vibration parameters, formalized for ease of use in the development of the algorithm code of the automated control of complex systems on the frequency set of basic features. The obtained research results have allowed possible to justify the need to implement an integrated diagnostic approach for conducting a detailed assessment of the technical condition of units in the parameters generated when the vibration. The article shows that only with the widespread use of the results obtained with the use of various modern methods of vibration diagnosticsit becomes possible to effectively identify defects equipment of complex equipment and the development of predictive models of degradation. As the foundation of the present study used the results of the analysis of existing approaches to the development unified diagnostic criteria based on the principles of vibration diagnostics extremely worn-out energy-mechanical equipment. Created complex diagnostic rules to detect emerging and developed defects pumping equipment according to the analysis of mechanical vibrations and developed united diagnostic status evaluation criteria can serve as a platform necessary for the implementation of the basic elements of technology service system in its actual technical condition. The results prove categorically the possibility of creating a group unified diagnostic criteria suitable for evaluation of the technical condition of centrifugal pumps and is a prerequisite for effective short-term forecasting of the investigated parameters in the development of adaptive mathematical models. It is proved that the results of short-term forecasting is sufficient and appropriate to the minimum necessary for the implementation of the basic elements of the system maintenance of pumping equipment for its actual state.

Key words: vibration analysis maintenance for the actual technical condition a single diagnostic criterion predictive modeling pump equipment
