【Power Range: 0.75kw-400kw】
【Energy-saving efficiency: 30% -65%】
Operation energy-saving principle:
The ordinary press oil pump is the fixed quantity pumpas the oil pump displacement is fixed, moreover the oil pump displacement design is the maximum value. When machine working, most of the hydraulic oil vent by the relief valve, resulting in a lot of energy waste. As the use of servo control system, pressure, flow use dual closed-loop feedback control, the servo system will provide pressure and flow as much as it needs. The servo motor current will also change with the needs of the system, work without energy consumption. When the compressor is in the packing or other conditions without action, the motor stops rotating, no current, the system does not consume any energy.
Using the compressor with servo system, system pressure, flow dual closed-loop. Hydraulic system in accordance with the actual needs of the flow and pressure to fuel, overcome the ordinary quantitative pump system high-pressure overflow generated by high energy consumption. In the clamping, stamping and other high-flow work stage, the motor in accordance with the speed preset. In the filler, picking and other low-flow work stage, reducing the motor speed. The actual pump energy consumption reduced by 25% - 45%.
2.Rapid response, high production efficiency
Rapid response and high production efficiency. Servo system response speed, pressure rise time and flow rise time as fast as 30ms. Improve the response speed of the hydraulic system, reducing the action conversion time, speeding up the machine running the beat. When compressor hydraulic system automatically running, there is a valve open, the system pressure will drop instantly, the servo system can quickly replenish oil within 30ms, restoring the pressure to the value preset.
3.Pressure stability and precision:
High servo system adjustment ability. Pressure closed-loop control mode makes the system pressure very stable. Pressure fluctuation is less than0.5bar, improving the quality of the product molding.
4.Oil temperature is low. From the start, oil temperature will rise 8 ℃ -10 ℃. No cooling water is required at room temperature 35 ° C. Less cooler, to extend the lifespan of machine, especially hydraulic oil, hydraulic wearing parts (such as oil seal).
5.Low noise. The noise of the hydraulic system is within 65 decibels, improving the operating environment of the machine.
