Product details
In servo hydraulic system, servo motor(s) and servo pump control the hydrocylinder(s). The output flow of oil pump depends on the rotation speed of servo motors. And the speed and positioning of the ram depends on the output flow of oil pump. The bending force depends on the torque of servo motor.
Since there is no throttle valve in the servo hydraulic system, all the energy generated by oil pump is transferred to hydrocylinder(s). No energy waste in the whole process, energy saving realized.
â– Â Â Lower Energy Consumption
â– Â Â Clearly Reduced Cooling Effort
â– Â Â Higher Operation Speeds, 35 % higher compared to hydraulic systems
â– Â Â Remarkable Noise Reduction, 50dB
â– Â Â Save more Than 30% Oil
â– Â Â Higher Stroke More Flexibility
