Servo hydraulic press-high efficiency and energy saving

May 21st at 11:13am

Foshan hydraulic press is an energy-saving and efficient hydraulic press that uses servo motors to drive the main transmission oil pump, reduces the control valve circuit, and controls the hydraulic press slide. Suitable for stamping, forging, pressing, straightening and other processes.

 

Compared with traditional hydraulic presses of the same type, the positioning is more precise; Machine operation is more user-friendly, with a user-friendly human-machine interface. Pressure, position, and speed can be freely set and adjusted on the computer screen; Adopting closed-loop system control, high pressure accuracy. In fully automatic production mode, it can be used in conjunction with automatic production lines, which can shorten the production cycle by about 20% compared to traditional models; By adopting a proportional hydraulic system control, it can meet the requirements of different processes for speed and pressure changes, and the movement is more stable; The pressing speed is fast, and the working cycle for pressing a single product is 4-5 seconds.

 

Servo hydraulic press - efficient and energy-saving

 

The energy-saving hydraulic station dedicated to Foshan hydraulic press adopts "pump controlled servo" technology, which achieves precise control of flow and pressure by accurately controlling the torque and speed of the pump. It mainly consists of several parts, including an electro-hydraulic servo driver, a three-phase AC permanent magnet synchronous motor, a high-performance specialized servo pump, and a pressure sensor. Due to the fact that the output flow of the oil pump is proportional to the speed of the motor, the pressure in the oil circuit is proportional to the output torque of the motor. By using vector control, weak magnetic control, and specialized PID control algorithms to achieve precise control of the torque and speed of the pump through dual closed-loop control of system pressure and flow, precise supply of flow and pressure according to actual needs is achieved, eliminating energy losses caused by high-pressure throttling, overcoming the problem of rapid oil temperature rise caused by high-pressure throttling in traditional "valve controlled servo" systems, achieving energy-saving and power-saving effects. At the same time, the system oil temperature is reduced, with a maximum energy-saving rate of 70% and an average energy-saving rate of 30%.

 

1、 Energy saving and emission reduction: Hydraulic and electrical control adopt intelligent servo energy-saving systems, saving 50% -70% electricity

 

2、 Safe and Precision: Each machine is equipped with an infrared safety grating to effectively protect operators. The servo intelligent patented control ensures that the machine's repeated positioning accuracy can reach ± 0.03mm and pressure error can reach ± 1%

 

3、 Low failure rate: The servo intelligent patented control system does not perform useless work, the oil temperature is not easy to rise, and there is no negative pressure in the oil circuit system, which greatly reduces faults and extends the service life of hydraulic components. The electrical equipment is equipped with automatic fault alarm and one key reset function.

 

4、 Stable and Durable: The frame adopts a complete machine frame structure, and the slider is guided by precision guide rails for operation, with strong shock resistance and lateral pressure resistance. The whole machine is stable, precise and durable, suitable for various process applications such as material dropping, forming, and extrusion.

 

5、 Easy maintenance: The whole machine is designed into modular structures according to different functional modes, making disassembly and assembly easy. General faults can be directly viewed through the touch screen, making maintenance simple.
