AI Technical Summary
Existing hydraulic systems for large forging manipulators struggle to balance high control precision, energy efficiency, and reliability under heavy loads, large inertia, and strong impact conditions. Traditional systems suffer from throttling losses, severe heat generation, and insufficient impact resistance.
By combining the working chamber with a closed pump control circuit, and integrating the compensation chamber with a multi-stage pressure accumulator, the control unit identifies the operating condition type and matches the pressure source to achieve high-precision drive and energy management, recovering and storing energy to improve system energy efficiency.
It significantly improves the system's control accuracy and response speed, reduces installed power and heat generation, enhances operational reliability, and adapts to heavy-load, high-inertia, and high-impact operating conditions.
