大有彩票开奖ALPHA6810S Energy Saver works intelligently in the injection cycles. The motor speed is controlled synchronously with the tracking of pressure and flow, which is equivalent to using a variable pump instead of the actual fixed-displacement pump. And the original hydraulic system works adaptively to the machine running power, eliminating the energy loss caused by high-pressure overflow in previous system. Furthermore, the AC Drive makes the motor stop running under non-action state (Mainly the cooling state) thus enlarges the energy saving space and reduces the running noise as well as machine wear and temperature-rise. This series of inverter perfectly combines the injection machine and the asynchronous servo controller’s advantages of rapid dynamic response and strong instantaneous over-current ability. Because of this, the energy saving of oil pump is 25%~70%, and hydraulic oil extends its lifetime to 3 years.
