Research of the conditions for the occurrence of vibratory processes in the automated control of pumping complexes based on precedents

Abstract

The precedent approach used for the automated control of operating modes of pumping complexes makes it possible to reduce or completely eliminate various unsteady hydraulic processes, including cavitation. The article discusses the conditions for the occurrence of oscillations of a hydrodynamic nature in pumping complexes, contributing to the emergence or activation of these undesirable processes, with the construction of models based on the method of electrical analogy and the application of stability criteria of the theory of automatic control. The results obtained allow the formation and use of a base of precedents when controlling the operating modes of pumping complexes, taking into account the oscillation factor.
