Energy-saving technology of Daikin
Fusion of oil hydraulics and motor/inverter technology
Energy-savings of more than 50% (In comparison of a conventional hydraulic system to our product while when pressure is retained).
The dramatic energy-savings is realized by reduction of the motor rotating speed under retained pressure condition.
The high-efficiency IPM motor will achieve energy-savings even in the general industrial machine field where the operation ratio of actuators is high.
Principle of energy-saving in terms of operating pattern (Case of Daikin SUPER UNIT).
The power consumption is dramatically
reduced under retained pressure
condition because of the variable
speed operation of our motor.
Differences between hybrid system and conventional system
Energy-saving
- ✖
- Constant motor rotating
speed at all time
- ◎
- Motor rotating speed is developed
as required
Noise
- ◎
- Quiet while retained pressure
Tank size
- ✖
- Large
(required for cooling of fluid)
- ◎
- Small (low heat generation
means less required capacity)
Machine configuration
- △
- Complicated (piston pump)
Cost
- 〇
- Low(on the parts of software)
- △
- High(Inverter is expensive)
- 〇
- Elimination of valves by use of
software & control reduces cost.
Engineering
- △
- Simple however there are
few people with oil hydraulic
skills and experience.
- 〇
- Technical skills are required. An
example is knowledge of how to set
software parameters is required though
the setting procedure is straightforward.
