1.Name:Integrated Hydraulic Servo System for Bending Machine
2.Introduce:Integrated Hydraulic Servo System,the pressure and flow controlled double closed-loop,by control the motor speed to control the oil supply of hyrauluc power unit.
3.Model:Model choose according to the customer's requirement.
4.Application:Can be used on Bending Machine,Shoe Machine,Vulcanizing Machine,Hydraulic Press,Injection molding machine,Lathe,CNC,Pipe Bender,wood-working machine and so on.
5.Feature:
Integrated Hydraulic Servo System used on Bending Machine have a huge advantage to compare with the tranditional Bending Machine hydraulic power unit.
(1)Compare with the tranditional Bending Machine hydraulic power unit the noise and temperature is lower.
(2)Efficiency Improving:Compare with the tranditional Bending machine hydraulic power unit efficiency can inprove 30%.
(3)Easy assemble and operate convenience.Before delivery out the engineer will set all the parameters according to customer's equipment.After get the system customer only need to connect the power cable.If customer want to adjust some parameters only need to re-set on the keyboard(include keyboard type and terminal type) or PLC of system accroding to the manual document.
(4)Compare with the tranditional Bending machine hydraulic power unit the Integrated Hydraulic Servo System performance is more stable.
(5)Cost Saving:Design,assemble and service cost is lower.
(6)Low interference:Integrated Hydraulic Servo System is Integrated,the driver is far away from control cabinet.
