Resumo: | Hydraulic systems have gained widespread use and applicability to the industrial manufacturing process. Although the hydraulic technology is old, there are many modern applications such as presses, mechanical excavators, backhoes, loaders, forklifts and cranes. However, studies show that the stability of the supply pressure is a determinant for gain efficient of any hydraulic equipment. This study aimed to analyze the characteristics of the variation in supply pressure in a hydraulic system under different conditions of operation, through a test bench. Were first showed constructive and operating characteristics of the major components analyzed, these being the proportional directional valve, pressure relief valve direct operated (relief valve) and the accumulator. Subsequently, addressed the relationship between the operation of the relief valve and the behavior of the supply pressure. In the experiments, the proportional directional valve is subjected to different conditions of pressure difference and aperture alternating also, the use of an accumulator in the circuit. The results show the relation between the operating conditions of the hydraulic circuit and the change in supply pressure. |

Were first showed constructive and operating characteristics of the major components analyzed, these being the proportional directional valve, pressure relief valve direct operated (relief valve) and the accumulator. Subsequently, addressed the relationship between the operation of the relief valve and the behavior of the supply pressure. In the experiments, the proportional directional valve is subjected to different conditions of pressure difference and aperture alternating also, the use of an accumulator in the circuit.
