TECHNICAL AND ECONOMIC RATIONALE FOR MODERNIZATION OF HIGH PRESSURE SPRINKLING MACHINES “FRIGATE”

Abstract

The article offers a feasibility study for the improvement and modernization of existing sprinklers in order to reduce energy consumption in the cultivation of crops. Here are some issues that need to be addressed. The purpose of the research on the possibility and expediency of modernization of existing obsolete high-pressure sprinklers “Frigate” in low-pressure modifications with simultaneous modernization of pumping equipment. It is proposed to re-equip the existing high-pressure sprinklers “Frigate” in the modification of low-pressure, which in turn will affect the improvement of soil cover. The characteristics and parameters of the proposed modern sprinklers are given. The example of calculation of economic efficiency of reconstruction of irrigation system is given, questions of introduction of energy saving technologies on irrigation system are considered, namely: re-equipment of sprinklers like “Frigate” of DMU B – 394–80 brand on modification of “Frigate” machine, DMU Bnm – 394-45 , by replacing high-intensity sprinklers with modern low-intensity and hydraulic cylinders; modernization of the pumping station, namely pumps of the brand 200 D 90 (200 D 60) on pumps 200 D 90 (200 D 60 b). The main technical and economic indicators before and after modernization are determined. The expediency and efficiency of the use of capital investments and their quick payback for the modernization of high-pressure sprinklers "Frigate" have been established.
