Hydraulic Servo Energy-saving System
The whole series adopts advanced permanent magnet synchronous servo motor combined with servo driver vector control technology
Why do traditional hydraulic systems consume energy?
Traditional hydraulic systems use a general purpose induction motor to drive the oil pump at a fixed speed. As long as the system starts, regardless of whether the equipment is actually running, it will continue to consume 30% ~ 40% of the rated power of the motor.
Due to the constant speed operation of the motor, when the equipment is in the stages of actuation, pressurization, pressure maintenance, cooling, material exchange, etc., the excess oil produced by the system returns to the fuel tank / pressure ratio valve / safety valve through a specific flow valve, which unnecessarily generates mechanical friction heat and noise.
How to save electricity and protect the environment in Hydraulic Servo Energy-saving System?
The hydraulic energy-saving system integrates servo technology and hydraulic technology, and adopts the combination of oil pump and permanent magnet synchronous servo motor.
According to the pressure and flow required by the equipment under different working conditions, pass through the dedicated hydraulic servo driver compared to the feedback signal of the pressure sensor, the speed of the servo motor is intelligently controlled after calculation to provide the actual pressure and flow required by the equipment.
The system has no standby overflow loss, greatly reduces power waste, and fully realizes simultaneous control of pressure and flow. It has the advantages of high efficiency and energy-saving, quick recovery of investment costs, high production efficiency and high precision control.
