Operating energy-saving principle:
The ordinary press oil pump is a quantitative pump. Due to the fixed displacement of the oil pump and the design of the maximum displacement of the oil pump, most of the hydraulic oil is released through the overflow valve during machine operation, resulting in a large amount of energy waste. Due to the use of a servo control system with dual closed-loop feedback control for pressure and flow, the servo system provides the required pressure and flow rate during machine operation. The current of the servo motor also changes according to the system's requirements, resulting in no energy consumption during operation. When the press is not in operation during filling, picking up, and other working conditions, the motor stops rotating, no current is generated, and the system does not consume any energy.

Characteristic advantages:
1. Energy saving:
The press adopts a servo system, with dual closed loops for system pressure and flow rate. The hydraulic system supplies oil according to the actual required flow rate and pressure, overcoming the high energy consumption caused by high-pressure overflow in ordinary quantitative pump systems. During high flow stages such as mold opening, mold closing, and stamping, the motor works at the set speed. During low flow stages such as filling and picking up, the motor speed is reduced, and the actual energy consumption of the oil pump motor is reduced by 25% -45%.
2. Rapid response and high production efficiency
The servo system has a fast response speed, with a pressure rise time and flow rate rise time of up to 30ms, which improves the response speed of the hydraulic system, reduces action conversion time, and accelerates the overall running cycle of the machine; When the hydraulic system of the press is running automatically, when a valve is opened, the system pressure will instantly decrease. The servo system can quickly replenish the oil volume within 30ms and restore the pressure to the set value.
3. Stable and precise pressure:
The servo system has strong adjustment ability, and the pressure closed-loop control mode makes the system pressure very stable. The pressure fluctuation is less than ± 0.5 bar, which improves the forming quality of the product.
4. Low oil temperature rise
The oil temperature of the press increases by 8 ℃ -10 ℃ from start-up to steady-state operation. At room temperature of 35 ℃, no cooling water is required, and the amount of cooler used is greatly reduced, which extends the life of the entire machine, especially the hydraulic oil and hydraulic vulnerable parts (such as oil seals).
5. Low noise
The noise of the hydraulic system is within 65dB, which improves the on-site environment for operating the machine.
