Improved design water injection regulator

In the Russian Federation, 80% of agricultural land is in unstable moisture. The economic crisis at end last century affected state reclamation hydraulic structures. large-scale reconstruction and construction systems planned until 2030 requires development new media for them. use renewable energy sources to control water supply heart injection flow controllers. structure an alternative automatic gates electromechanical actions uses hydrodynamic properties its operation. previously obtained theoretical relationships calculation regulator considered as a kind injector located under dam or embankment. To further optimize shape path regulators, analysis modern improvement water-jet pumps was carried out, taking into account operation structure. improved design model tested laboratory, characteristics were experimentally, estimated random errors direct indirect measurements obtained. limiting position boundary streamline before mixing chamber theoretically. For first time, drag coefficient rectangular asymmetric diffuser with large expansion angle shortened dividing walls has been experimentally smooth dissolution flow, leading edges are placed outside inlet section diffuser. Variants network when enters tailwater volume considered. change elements, made accordance recommendations devices, makes it possible increase circulating representing excess that develops downstream sprinklers turned off. After modernization, range pressures on significantly increased. This opened up possibilities application. Studies have shown form execution without introducing rigid nozzle final pressure head part outlet. confluence flows, which injected initial similar streamlined body, not capable optimal ratios areas chamber, affect efficiency injectors.
