ABSTRACT: The study purpose is to substantiate the energy conservation technology of water lifting from watercourses and to conduct the theoretical and experimental studies of the water lifting technique using the hydro power of watercourses. The recently developed constructional and technological schemes of the pumping units of water hammer and suction-delivery types driven by the watercourse energy are presented, which in comparison with their analogues have the advantage of improving energy indicators. The results of the theoretical researches on the water hammer and suction-delivery techniques for water lifting from watercourses are provided, on the basis of which the major technological parameters such as total head, flow rate, pump power, and efficiency are determined, technical parameters are substantiated, and experimental models of pumping units are manufactured. The positive results of the experimental studies and tests are given.
