Design of sprinklers from a resource-saving perspective

Abstract

Sprinklers created in the Soviet period and still widely used in the fields today, in many respects no longer meet modern requirements, do not guarantee high-quality watering and reliable operation. It is necessary to develop new design principles, concepts, new techniques and approaches, to clarify the required parameters and characteristics. It is important not only to modernize and restore the irrigation equipment in operation, but also to produce new reliable, high-quality machines. One of the current trends in the design of sprinklers is the principle of resource conservation. The article defines the directions of improvement of structural and technical parameters, presents the design concept depending on the operating conditions. The ways of reducing the metal consumption, and consequently the cost of machines, are considered. Obvious ways to reduce the metal consumption of machines include increasing the span between the trolleys and reducing the weight of the truss water belt by improving the design. Optimization of the truss water belt allowed to increase the span length by 22.1-33.8% with a slight increase in weight by 5.8-15.1%.
