3.Advantages of Servo System
Energy saving
Compared with the traditional variable pump system, the servo oil pump system combines the fast stepless speed regulation characteristics of the servo motor and the self-regulating oil pressure characteristics of the hydraulic oil pump, which brings huge energy saving potential, and the energy saving rate can reach up to 30%-80%.
Efficient
The response speed is fast and the response time is as short as 20ms, which improves the response speed of the hydraulic system.
Precision
The fast response speed guarantees the opening and closing accuracy, the position accuracy can reach 0.1mm, and the special function position positioning accuracy can reach ±0.01mm.
The high-precision, high-response PID algorithm module ensures stable system pressure and pressure fluctuations of less than ±0.5 bar, improving product quality.
Environmental protection
Noise: The average noise of the hydraulic servo system is 15-20 dB lower than that of the original variable pump.
Temperature: After the servo system is used, the hydraulic oil temperature is reduced overall, which enhances the life of the hydraulic seal or reduces the power of the cooler.

Safety blocks
Lock nuts are provided for movable parts
All action of press have safety interlock function, e.g. movable worktable will not work unless cushion return to initial position. Slide can not press when movable worktable is pressing. When conflict operation happen, alarm shows on touch screen and show what's the conflict.
Hydraulic System
1.Oil tank been set forced cooling filtering system(industrial plate-type water cooling device, cooling by circulating water, oil temperature≤55℃，make sure machine can steadily pressing in 24 hours.)
2.The hydraulic system adopts integrated cartridge valve control system with fast response speed and high transmission efficiency.
3.The oil tank is equipped with an air filter to communicate with the outside to ensure that the hydraulic oil is not polluted.
4.The connection between the filling valve and the fuel tank uses a flexible joint to prevent vibration from being transmitted to the fuel tank and completely solve the problem of oil leakage.
