Features: Energy saving; by controlling speed of pump, the flowing rate changes. Even the system requires few flowing rate with high pressure, the pump can deliver such flowing rate and pressure in low ratation speed. Precisely control system; the hybrid servo system controller accesses the signal feedback from the sensor to be controlled rapidly. It accurately controls and the pressure and position performance. Flowing space saving; by using special proportional valve to control the speed, thus the system saves the space from flowing valves. Multiple cylinders operation; controlling multiple cylinders with one pump by changing the controlled cylinder at its procedure, that also save energy. It minimized the investment. Comparing the energy consumption between ordinary and servo system. At each average, the servo system spends only half of the energy.
