EXPERIMENTAL RESEARCH OF INFLUENCE CAVITATIONAL PROCESSES ON CHARACTERISTICS ELECTROMECHANICAL SYSTEMS OF PUMPING COMPLEX

The analysis of works devoted to the study of cavitation in the pump complexes. It is shown that existing work on the investigation of the cavitational processes have left untouched the impact of such processes on the mechanical and energy characteristics of Electromechanical systems pumping of the complex. The description of the physical model of the pump complex, one of the research capabilities of which is the study of cavitation processes in hydrotransport sys-tems. The obtained experimental curves of changes of technology, mechanical and energy characteristics of the pump unit in the presence and absence of cavitation processes in the pipeline, the analysis of which showed the influence of cavitation oscillations in mechanical and energy characteristics of Electromechanical systems. The resulting error in the determination of relative values of critical frequency of rotation of the impeller pump that matches cavitation free work pumping complex obtained by theoretical calculations and experimental curves.
