| Abstract | ||||
| The industrial variable displacement of axial piston pump conical cylinder has wide application in hydraulic drives of mobile machinery in view of some advantages, such as good features good suction characteristics , low noise level,small dimensions and weight at high values of working pressure. Also good solutions in presses, milling production line machine, stucker in cement production line. Our pump with constant power regulator has many applications but is a good solution in deep drawing presses used in home appliance industry very spreader in Egypt .I replaced an old line of pumps. So the study of this pump with specified control is essential to develop a model validated. This paper is dedicated to investigate the steady state and dynamic performance of this class. The pump controller is of rocker-arm type, it serves to produce constant output hydraulic power. The study includes the development of non-linear mathematical model of the pumping mechanism and the pump controller. The mathematical models were used to develop computer simulation programs by using Simulink-matlab program. The study included an experimental part where the steady state and transient responses were measured. An acceptable agreement between the simulation and experimental results was observed, which validates the developed simulated model program.The simulation model program was used to conduct a parametric study. The results are presented and analyzed. | ||||
