SUBSTANTIATION OF THE KEY PARAMETERS AND OPERATING MODES OF THE DRUM-TYPE SPRINKLER
In the article the analysis of the works on the hydraulic design of a flexible pipeline wound on a screw line is carried out, the technique of substantiation of hydraulic and design parameters of a drum-type sprinkler is stated. The formulas are offered, which allow calculating a minimum admissible pressure at the water-supplying system input and selecting rational parameters of the flexible pipeline. The chart for definition of artificial rain characteristics and device parameters reflecting the results of theoretical research is presented. As a result of the experimental investigations the mathematical model of the response surface is constructed and, proceeding from the agrotechnical requirements on the artificial rain quality the optimal device parameters, at which the maximum productivity is reached, are determined.
