ELECTROHYDRAULIC COMPLEX ENERGY MODEL WITH TECHNOLOGICAL PARAMETERS PERIODIC CHANGE

It has been proposed electrohydraulic complex equivalent circuit taking into account of cavitation processes in the pipeline network. It has been shown that the change in the pipeline hydraulic resistance in time due to periodic cavita-tion self-oscillations, with a sufficient degree of accuracy could be represented by a trigonometric series. It has been found that the use of the hydraulic power harmonic analysis allows to allocate additional variable components generated by cavitation effects, perform energy processes spectral analysis in the hydraulic system. Energy model on the basis of the energy balance equations of the power components between the source of hydraulic power and hydraulic system elements. Formation test harmonic action provides the possibility of obtaining the required identification equations number for finding the required of the electrohydraulic complex parameters.
