Advantages of servo hydraulic press compared with ordinary hydraulic press

The new servo drive hydraulic press (referred to as servo hydraulic press) is an energy-saving and efficient hydraulic press that uses servo motor to drive the main transmission oil pump, reduce the control valve loop, and control the hydraulic press slide block. Servo hydraulic press advantages and functions are as follows:

I. Energy Saving

Servo hydraulic press compared with ordinary hydraulic press, the overall control of the system does not contain proportional servo valve or proportional pump link, the service drive hydraulic press has the advantages of energy saving, low noise, low temperature rise, good flexibility, high efficiency, easy maintenance, etc., according to the processing technology and production beats are different, servo drive hydraulic press can save 30% ~ 70% compared with traditional hydraulic press.

Second, low noise

Servo driven hydraulic pump generally uses internal gear pump or high performance vane pump, traditional hydraulic machine generally uses axial piston pump, in the same flow and pressure under the internal gear pump or vane pump noise is lower than the axial piston pump 5dB ~ 10dB. When the servo drive hydraulic press is pressed and returned, the motor runs at the rated speed, and the emission noise is 5dB ~ 10dB lower than that of the traditional hydraulic press.

Third, less heat, reduce costs

Because the hydraulic system of the servo drive hydraulic press has no overflow heat, there is no flow flow when the slider is stationary, so there is no hydraulic resistance heat, and the heat of the hydraulic system is generally 10% to 30% of the traditional hydraulic press. Due to the low heat output of the system, most servo-driven hydraulic presses do not have hydraulic oil cooling systems, and some of the large heat output can be set up a low-power cooling system.

Fourth, high degree of automation, good flexibility, high precision

The pressure, speed and position of the servo drive hydraulic press are fully closed loop digital control, with high degree of automation and good precision. In addition, the pressure and speed can be programmed to meet the needs of various processes, and remote automatic control can also be achieved.

5. High efficiency

Through appropriate acceleration and deceleration control and energy optimization, the speed of the servo control hydraulic press can be greatly improved, and the working beat is several times higher than that of the traditional hydraulic press, which can reach 10/min ~ 15/min.

Six, easy maintenance

The hydraulic system is greatly simplified because the proportional servo hydraulic valve, speed regulating circuit and pressure regulating circuit in the hydraulic system are eliminated. The cleanliness requirement of hydraulic oil is much less than that of hydraulic proportional servo system, which reduces the influence of hydraulic oil pollution on the system.
