摘要：The computational and experimental work was carried out using the SolidWorks system. The main structural parameters of a hydrodynamic cavitation unit, designed to prepare irrigation water in the process of watering plants and pre-soaking seed before seeding, are determined. The unit has been manufactured and tested. It was established experimentally that the opening angle of the impeller wedge should be 40 and 800, and a sufficient rotor speed – 10.000 rpm. A more effective form of a hydraulic brake for this cavitation unit was determined, which made it possible to obtain irrigation water with a pH of from 7.2 to 8.5 on average, and an oxygen content of 4.6 to 6.5 mg / l. It is shown that cavitation allows the use of water for irrigation, even from polluted natural sources, since the process of purification of polluted wastewater proceeds in parallel.
