dc.description.abstract | The paper presents a mathematic model of static and dynamic characteristics for casting machine. This machine has a hydraulic action for the casting chamber (her closing and introducing of molten alloy). This action is made by use an axial piston pump with the variable cylinder with pressure regulator. The mathematic model of how the injection pump functions (for molten alloy) can do by a computer simulation. This kind of approach for the study problem leads to the identification of key parameter and malfunction of these hydraulic parts. The malfunction simulation for the important work parameters (hydraulic force necessary to push the molten alloy in the shell, pressure compensated flow controls the strength to close the two rooms where the molten alloy is sent) show permanently the operator the place where a damage is produce and it is necessary his intervention. | ro_RO |
