省エネ射出成形機サーボ90Eからサーボ570Eへの切り替え

エネルギーの節約=地球を救う

成形条件のさまざまな設定によれば、Servo Eは、可変容量ポンプまたはインバーターを備えた機械よりも40％少ないエネルギーを消費し、固定容量ポンプを備えた機械と比較して平均60％少ない電力を消費します。

LESS VOLUME OF OIL & COOLING WATER CONSUMED

Servo E has no issues of oil heat generation caused by the flow relief valve in the IMM with a fixed pump, or oil draining by the IMM with a variable pump, so a smaller capacity of heat exchange and less volume of cooling water are required. The oil consumption is cut in half so, the oil storage and the cost of refilling are lower. The standard hydraulic design of the logic circuit shortens the response moment of the hydraulics and achieves pressure/speed control precisely.

ECONOMY SERVO ENERGY SAVER

The ASE servo pump unit consists of a servo driver from the global brand ABB, a Taiwanese, synchronous servo motor, and a German internal gear pump from Eckerle/Voith. The pressure is controlled by a proportional valve that is based on closed-loop processes, while the flow is supplied by a rotary speed servo motor, timing the displacement of the gear pump. A detecting encoder tunes the motor RPM to keep the correct speed and to get an exact system flow.

MORE BENEFITS FROM SERVO E MACHINES

Higher Precision: The closed-loop pressure and the flow controller, perfectly, transmit commands and real values for different functions. The controller receives the commands from the PLC. It inspects the real value of the working devices, and then it gives a feedback signal to the PLC for micro-tuning. The linear tolerance and hysteresis for pressure and flow is less than 1%. It substantially improves the precision in the molding.
Stable Operation: A perfect integration of the mechanical, hydraulic and control sections for upgrading the machine performance and the molding reliability.
Sufficient Motor Torque: Even under maximum rotary speed, the servomotor is steadily producing enough torque force to avoid pressure overshoot at the transition from the injection stage to the pressure holding stage.
