摘要
This article presents dynamic analysis of a selected hydraulic system provided with a lift valve, whose schematic diagram corresponds to the control of positive-displacement pumps in the feeding system of the pressure casting machine. A mathematical model of the lift valve which illustrates the effect upon the working dynamics of the hydraulic system exerted by control nozzle diameter values was presented.
Finally the simulation results, for different values of nozzle diameters were graphically compared together.
