ECO-RICH HYBRID POWER UNIT
Epoch-making energy saving 50% (Compared to our product, when pressure is retained)
- Drastic energy saving by reducing the motor rotating speed under pressure-retained condition
- Our original SR motor control unit of high efficiency and compact fixed-displacement pump are employed.
High-speed response
- Special SR motor, which has low inertia and generates high torque at low speed, and high-speed response inverter
- Response equivalent to or higher than conventional variable displacement pump (Pressure retained operation at maximum flow rate:0.1sec or less)
Autonomous energy saving pressure — flow rate control
-
Supplies required flow according to load condition by monitoring the pressure.
-
Holds necessary pressure and operates at the minimum rotating speed required to compensate for leakage from circuit in retaining pressure. Rotates at high speed and supplies required flow when hydraulic actuator operates.
Space saving and Resources saving
-
Resources saving type with compact, lightweight, and simple structure with no permanent magnet (50% compared to our conventional unit)
-
Minimized fluid is supplied at low-speed rotation to improve the hydraulic oil in deterioration
Easy Installation and easy operation
- Only connect to 200V commercial power source to operate
- Pressure and flow rate can be set on the touch panel.
- Pressure and flow rate are legibly displayed in digital.
