Comparison of Servo Hybrid System

: Conventional Hydraulic System; Command; Controller ▶Proportional control valve command; Controller ▶ Pump operation command; Driving Principle; Continuous motor and pump operation; Proportional control valve delivers only necessary flow to the operating mechanism; The rest of the flow is bypassed (loss); Feature; Motor operating ratio more than 50% under no load condition; 1200rpm motor, large capacity pump are used; Electronic proportional control valve response time 80ms or above

: Servo Hybrid Hydraulic System; Command; Controller ▶Servo Drive▶Servo Motor▶Pump rotation; Driving Principle; Servo Motor and pump make a Optima necessary flow and pressure for operation; Only Directional control valve controlled the operating mechanism; Flow and pressure feed-back control; Feature; Motor was no operating under no load condition; 0~2500rpm variable speed control, make a large flow using small displacement pump; Response time 40ms(simila as Electric Machine); Precision machine control using servo system

01 Machine Diagnosis: Measure power consumption, examine the specification and performance of the machine to be remodeled; Refer to technical data (hydraulic & electric circuit drawings; Work Environment

02 Quotation: Quotation of the servo hybrid system based on the machine specification; Consult financing

03 Agreement: Discuss and set the delivery terms; Delivery schedule according to financing method

04 Remodeling and commissioning: Components involved (servo motor, servo drive, servo pump, Hydraulic block, hydraulic piping and electric box); No need to edit the program of the existing controller (Use existing electric signals)

05 Installation completion report: Power consumption rate testing; Training and machine transfer

Save energy by optimizing oil flow and pressure according to the machine operation.
During holding step, maintain pressure at minimum speed
During cooling step, no operation, using no energy
