Hydraulic Press in New Age --Drive your press with servo

2. Features, Advantages & Benefits 1. Introduction Contents 3. System detail 4. Case & Data

Pressure and flow double closed- loop control ESTUN servo system PQ Decoupling control algorithm Rexroth (or specified) Internal gear pump 1.Introduction-SVP SVP –Servo Variable-speed Pump (each pump 25cc ~250cc) SVP system is formed by pressure and flow double closed-loop control. The power and speed of whole press system is optimum adjustable, after SVP replaces the classic AC motor and pump system.

Triple protection high overload capacity 1‰ repeatability precision ±0.3bar accuracy ±0.1mm Injection Flow response 20ms Pressure response 70ms Decompression time120ms Permanent magnet synchronous servo motor PQ Decoupling control algorithm 40%~80% Energy saving Energy saving High Efficiency DurableAccuracy 1.Introduction-SVP
