![]() ![]() Based on the information analyzed throughout this study from drawings, calculations and simulations, the developed prototype is technically feasible for agricultural applications since it presents reduced dimensions, adequate pressure and flow, and also simple mechanical requirements. The prototype operating equations showed values for the average flow rate Q = 0.00029134 m³ / s, specific energy supplied to the liquid Y = 22155.878 J / kg and pressure drop in the valves □□ = 0.9822 mca. ![]() The cracks found on the carcass during the failure analysis contributed with the computer simulation by the FEM, proving to be a reliable analysis. The prototype was tested at constant speed of 150 rpm, and also at constant speed of 300 rpm, presenting approximately 87 bar of working pressure before breaking off. The pump casing was subjected to a computer simulation using the Finite Element Method (FEM), which showed stress concentrating points along the working body and other aspects related to safety factors, torsion in the casing and others. The prototype under analysis has the advantage of a reduced size and high working pressure, ideal for spraying crops and transporting fluids between short distances, without using electricity. This study aims to explore the technical feasibility of a positive displacement hydraulic pump, with a double-acting axial piston, driven by the power take-off of tractors of various types. High quality Rexroth Bombas hidraulicas A10VO71 A10VO74 series LA 10VO74DFLR/31L-PSC12N00-S06 High Pressure Piston Pump. The development of a prototype that can be used in situations of scarcity of resources and activated by the tractor itself encourages the possibility of saving time for certain agricultural tasks, as well as the practicality of using simple maintenance and handling equipment. El fluido puede ser líquido, o una mezcla de líquidos y sólidos como el hormigón antes de fraguar o la pasta de papel. The use of this type of pump in remote locations presents restrictions due to the size of the equipment and its peripherals, the type of drive and even its mechanical complexity regarding maintenance. VEVOR Bomba Hidráulica 4L Bomba Hidráuli Eléctrica 2850R / MIN Bomba Hidráulica de Acción DC 12V Bomba Hidráulica con Tanque de Combustible 1. Máquina que transforma la energía (generalmente energía mecánica) con la que es accionada en energía hidráulica del fluido incompresible que mueve. The use of these pumps presents the possibility of working with viscous fluids and with suspended particles, either in pressurization or atomization services according to the working fluid. Among the existing types of pumps, positive displacement piston pumps operate with low flow and high pressures, with the fluid displaced from suction to discharge in defined and continuous volumes. Hydraulic pumps assign energy to the fluid to transport it by flow from one point to another, converting mechanical work into energy for operation. ![]()
