Pankiv Y. Development of the method and system for the technical state control of pump aggregates in the oil-fields stratum pressure support systems.

The thesis is devoted to the significant scientific and technical problem of new method and system development for controlling the technical state of centrifugal pump aggregates (CPA) used in the systems of stratum pressure support (SPS) with the aim to increase the reliability of its exploitation. The main features of CPA, reasons and factors which predetermine the causes of their defects and refusals were reviewed. The analysis of centrifugal pump aggregate as the object of vibrodiagnostics was performed, which allow us to define and to confirm experimentally the number of the possible vibration sources and to develop it’s diagnostical model was performed. The analysis of experimental researches of the CPA operating parts vibration influence with its technical state changing was performed, the diagnostical value was defined, and developed a new control method, based on it..
