Replace valve control technology with pump control technology, eliminate throttle loss, no overflow loss, energy saving effect is significant (can save 60% of electricity)
Tank volume reduced by 75%, reducing the use of hydraulic fluid.
Low heat balance temperature, no need for cooling device, extended life of hydraulic components
The servo motor can be significantly overloaded in a short time, and the actual installation power is only 50% of the theoretical installation power.
The high-performance special controller combines various advanced control strategies, such as pressure closed-loop, position closed-loop, position pressure compound control and synchronization control, to achieve the compound control of position, pressure and flow. The repeated positioning accuracy of the system is up to ±0.005mm, and the synchronization accuracy is within ±0.020mm
Electro-hydraulic servo press is the electro-hydraulic servo mix by controlling the servo motor driven hydraulic pump control system to implement two-way pump load position, speed, pressure closed loop control, maximizing the servo control and the advantage of two aspects of the hydraulic control, is the best way of combine the servo press and digital electronic hydraulic press.
DSVP electro-hydraulic hybrid drive system can achieve high precision pressure, position and synchronization control. The repeated positioning accuracy of the system is ±0.005mm, and the synchronization accuracy is within ±0.02mm.
Sensitivity demands of hydraulic oil particles decreased from NS7 to NS9.
Compared to the electric drive, there is no need to replace the ball screw and grease maintenance.
A 1000KN bending machine equipped with DSVP energy saving system can reduce co2 emissions by 6000Kg per year, equivalent to planting 330 trees. It can also save 150 liters of hydraulic oil and extend the life of oil products by three times. Save 6,000 KWH per year
