Hydraulic Servo Energy-saving System

Saves 50%~80% energy. The whole series pairs permanent magnet synchronous servo motors with vector-controlled servo drives.

Why do traditional hydraulic systems consume energy?

The hydraulic energy-saving system integrates servo technology and hydraulic technology, and adopts the combination of oil pump and permanent magnet synchronous servo motor.

Benefit results after using Hydraulic Servo Energy-saving System

2-3×

High dynamic response

The whole series adopts permanent magnet servo motor, the speed response is more than 2~3 times higher than that of the induction motor (the hydraulic response time is within 0.1 seconds), with full-speed high-torque and high-efficiency operation.

-30%

Save water and oil

The oil temperature of the system is greatly reduced, the components inside the sealed oil circuit are more durable in use, the required maintenance times and oil change intervals are reduced, and the cooling water consumption can be saved by more than 30%.

-15dB

Reduce ambient noise

Reduce equipment noise and reduce operator fatigue.

35-85%

Energy saving and environmental protection

Energy saving benefits reaches 35%~85%. 25%~55% of the processing cost of plastic injection products is electricity, by using energy-saving systems, the competitiveness of products can be immediately improved.
