CALCULATION TO DETERMINE THE TECHNICAL AND ECONOMIC EFFICIENCY OF PUMPING UNITS FOR LIFTING WATER FROM WATERCOURSES POWERED BY WATER ENERGY FOR WATERING PASTURES AND IRRIGATION OF LAND

The problem of effective water supply using natural energy resources of water in modern conditions is promising and relevant, the solution of which is rationally carried out from watercourses with the necessary standard sizes of a hydraulic ram pumping unit, the design of which has a novelty. At the Kazakh National Agrarian Research University conducted applied research to improve the efficiency of water supply from watercourses in the system of irrigation of lands and irrigation of pastures of peasant and farm farms of the agro-industrial complex of the Republic of Kazakhstan through the development of an improved hydraulic ram pumping unit with an increase in its energy indicators: hydraulic shock pressure, supply, pressure and efficiency. This article presents a calculation to substantiate the economic efficiency of the studies carried out on the use of the necessary standard sizes of an improved hydraulic ram pumping unit (NUV-7-12 and NUV-17-20) for water supply to peasant and farm farms of the Republic of Kazakhstan and irrigation of lands located in areas of adjacent watercourses, compared with basic pumping units (AN - 2K - 9 - M1 and ANS-60 D).
