Justification of the regulation of the flow of sprinklers of wide-reach circular machines

Abstract

The article discusses the issues of substantiating the reliability of the movement of wide-reach circular sprinkler machines on elevated slopes by eliminating surface runoff in the movement zone of their running systems, especially in the end part, by equipping sprinkler machines with advanced membrane-type flow regulators. Laboratory studies have determined that the accuracy of regulation by the im-proved regulator is within the same limits as for its serial model, and is ± 5%. It has been found that the regulation of the flow rate of sprinklers in the end part of the DM on a sloping surface increases the value of the bearing capacity of the soil, from 40-50 to 80-90 kPa, or that at a specific pressure of running systems, on average, about 85 kPa, provides sufficient permeability
