Hybrid Retrofit System for Hydraulics Machinery

Hybrid Retrofit System for Hydraulics Machinery Servo Hybrid System is a hybrid system composing of the most advanced DRIVE, MOTOR, PUMP and other parts adequate for injection molding machine, pressing machine and etc. It is an electric and hydraulic integrated system applied of the most advanced technology, achieving maximum power saving (75%↑), high precision, high responsibility and eco-friendly effect.

Servo hybrid system, which controls only the necessary pressure and speed at the perfect timing, has all of economic, technical and environmental effects with both of electric and hydraulic machine’s advantages.

  • Advantages of electric machine : high precision control by CLOSED LOOP, etc.
  • Advantages of hydraulic machine : high pressur maintenance, low preservation cost, etc.

By retrofitting hydraulic machine to hybrid machine, it can present the same advantages and effects of new hybrid machine by converting its performance, functions and features.

Servo Hybrid Retrofit Business

• Comparison of Hydraulic System and Servo Hybrid System of Injection Molding Machine

  Conventional Hydraulic System Servo Hybrid System
Control Method
  • Controls PLC-Proportional control valves –OPEN LOOP Control
  • Induction motor-vane, Gear hydraulic Pump
  • Controls PLC-Servo Drive-PID CLOSED LOOP
  • Servo Motor – Servo-Hydraulic Pump
Driving Principle
  • Operates electric motors and hydraulic pumps all the time (100%)
  • Delivers required pressure and flow rate from proportional control valves
  • Produces bypass waste of residual flow rate
  • Servo motor-pump sends only required flow volume-precision in output
  • Controls direction switch of actuator in Direction Control Valve
  • Controls required flow rate (Q) and pressure (P) feed back
Main Characteristics
  • More than 50% in motor utilization rate during no loading
  • Use high-capacity pump with 1200 rpm fixed motor
  • 180ms in response time of electric proportional value speed control
  • No operation during no-loading (0~10rpm)
  • Optimum pump as a 0~2300rpm servo motor
  • Precision pressure, flow control in servo drive
