Servo hydraulic press adopts servo motor to drive the main transmission oil pump, and the hydraulic press cylinder is controlled by the hydraulic press is called the servo hydraulic press. Servo hydraulic press has been widely used in industry with its advantages of high positioning accuracy, energy saving and environmental protection, good product rigidity, low noise pollution, high working efficiency, good flexibility, and fast system response speed, large load stiffness. It can show the following advantages:
1, low oil temperature: servo hydraulic press generates less heat, reducing the cost of refrigeration, but also reduce the cost of hydraulic oil consumption: The servo hydraulic press system eliminates the relief valve control press, and the pressure oil will not cause heat through the relief valve, and the motor is not rotating when the standby time, so it will not produce excess flow rate and hydraulic resistance heat, the heat generated by the servo system is only 10% to 30% of the traditional hydraulic press. Because the pump of the servo system does not rotate most of the time, and there is less heat. Therefore, the oil tank can be smaller than the mailbox of the traditional hydraulic press, and the oil change time can also be extended, so the hydraulic oil consumption of the servo hydraulic press is only about 50% of the traditional hydraulic press.
2, digital control: the servo hydraulic press has a high degree of automation, good flexibility and accurate accuracy: the servo hydraulic press system is a full closed-loop digital control, which can reduce errors. The position, pressure and speed of the servo system are programmed for digital control and display to meet the needs of more precision press assembly production.
3, low noise: servo hydraulic machine noise is small: servo hydraulic machine oil pump generally uses internal gear pump, traditional hydraulic machine generally uses ordinary external gear pump and blade pump, after testing has proved that under normal working conditions, the noise generated by servo hydraulic machine is about 30% less than the noise generated by the traditional hydraulic machine of the same specification.
