Abstract
The article critically analyzes traditional methods of forming drops of defoliants and liquid chemicals. As an object of study, a sprayer with a perforated turbulator was selected, which ensures the formation of fine droplets on a short spraying torch. The degree of crushing of the working fluid, design parameters and operating modes of the proposed sprayer are investigated. Based on theoretical studies, analytical dependencies that reveal the physical properties of the sprayed liquid are analyzed, a description of the device and the principle of operation of the sprayer equipped with a perforated turbulator is given. The above analytical dependencies allowed more purposefully improving the design of the proposed atomizer.
