An analysis of various ways of regulating pumping units during the operation of pumping stations has shown that when controlling the water supply schedule, the most optimal way is to change the speed of rotation of the impeller shaft. The authors analyzed the graphs of changes in hydraulic efficiency due to changes in rotational speed, the operating characteristics of the pump at an efficiency other than the nominal value, and identified specific features of the operating modes of irrigation pumping stations. This article is devoted to this topical issue.
