Analysis shows reduced electricity costs in irrigation using low-pressure pumps in irrigated areas, suggesting improved efficiency.
The article shows that in order to improve the efficient operation of irrigated areas it is necessary to identify ways to reduce operational costs, including by reducing the consumption of electricity for irrigation at pumping stations. The purpose of the study is to assess the efficiency of use and energy costs of irrigation with multiple-horizontal dosage machines "Cascade" depending on the features of the irrigated area and used pumping units. Studies have established the change of water consumption of DM "Cascade" depending on the length of the machine and head at the inlet. Researches in LLC "Vremya-91" and LLC "Listeko" confirmed that the introduction of low-pressure DM "Cascade" and low-energy pumps (1D500-63, 300D70), working with optimal water consumption can reduce electricity consumption for irrigation in 1.87-2.05 times compared to high-pressure pumps D1250-125. The directions of further reduction of electricity consumption in these areas were determined.
