Abstract:

In order to analyze the fault of hydraulic transformer which failed to work in long-stroke pressurizing because of its too long return time, a simulation model about hydraulic transformer system of 300MN forging hydraulic press was established based on AMESim software. The influence of opening height of drain valves and pressure of liquid-filled tank on the return time of hydraulic transformer was simulated quantitatively. The condition, which would result in fault, was obtained and used to analyze the actual fault. The result shows that the fault can be eliminated through reducing the space between the cam plunger and drain valve stem by 4.6 mm.
