A servo hydraulic system is a system that enables its output, such as displacement, velocity, or force, to automatically, quickly, and accurately follow changes in input, while significantly amplifying output power. The working principle of servo hydraulic press is that the servo motor directly drives the gear pump for oil supply, with stable pressure. The servo hydraulic press has high precision in the downward repetitive positioning of the spindle, adopts pump control technology, is energy-saving and environmentally friendly, has good rigidity, and low noise. High efficiency, good flexibility, hydraulic servo systems have been widely used in industrial control due to their unique advantages such as fast response speed, high load stiffness, and high control power.
