Abstract
The methodology of substantiation and formulas are given, according to which the values of technological and technical parameters of three standard sizes of an improved hydraulic ram pumping unit for lifting water from watercourses are determined: one standard size for watering pastures and two standard sizes for irrigation of land plots of peasant and agricultural farms of the Republic of Kazakhstan, developed at the Kazakh National Agrarian Research University while carrying out research on applied research and the IRN-DP21682075 project "Pumping units for lifting water from watercourses powered by water energy" through JSC "Science Foundation" of the Ministry of Education and Science of the Republic of Kazakhstan (Contract No. 102 dated 11/10/2023).
The following technological and technical parameters of an improved hydraulic ram pumping unit for lifting water from watercourses powered by water energy are substantiated: the speed of water in the intake filter, the internal diameters of the intake filter, the supply pipeline, the water lifting pipeline (sleeve), the diameters of the through sections: shock and discharge valves, the length of the supply pipeline.
The field of application is the agricultural water supply of agricultural facilities of the Republic of Kazakhstan (peasant and farm farms and other agricultural formations) in areas with watercourses during the spring, summer and autumn periods of use. The distinctive features of a hydraulic ram pumping unit are the lifting of water using energy-saving and environmentally friendly water lifting technology by using the kinetic energy of the water flow in watercourses (geometric and high-speed heads) to drive and create hydraulic shock pressure in the supply pipeline from the periodic closing and opening of the hydraulic shock valve installed in it, as a result of which the supply and pressure in the pumping unit are created.
