Oil Hydraulics

Daikin’s unique oil hydraulic technology is changing the world's production sites
By applying IPM motor and inverter technologies cultivated from our air conditioning business to oil hydraulic systems, Daikin is pursuing the possibilities of power control technology that combines multi-stage pressure and flow rate control to provide energy savings for industrial machineries in the world.

Daikin Advantage

Daikin have focused on the process lines in a factory where 45% energy is consumed generally.
Daikin unique oil hydraulic systems which integrates oil hydraulic control and inverter motor technologies will be able to reduce power consumption significantly.

Energy consumption of process lines at factories

45% of total power consumption in factory is consumed in machining line.70% of machining line is the fixed consumption regardless of production volume.
Most of the fixed consumption consists of hydraulic unit, oil cooing, and coolant pump. Though it is important to reduce these three parts, nobody touched this area because of direct influence on production. Energy-saving activity by reviewing machining facilities is indispensable to protect environment and improve productivity.

Daikin Oil hydraulics with Energy Saving Technology

Integration of Daikin-original high efficiency IPM motor and Hydraulic technology

A rare-earth permanent magnet deeply positioned in the rotor can generate magnet torque (attraction/repellence between coil and permanent magnet) and reluctance torque (coil attracts iron). This electromagnetic structure attains high torque , highest efficiency and low heat generation.

Energy saving 50%

Drastic energy saving by reducing the motor rotating speed under pressure–retained condition.

Double pump system on Super unit

Significant energy saving and low–noise operation is attained by autonomous switching of fixed capacity double pump system.

Idling stop function

Utmost energy savings achieved in Super EcoRich with built-in idle stop function*1 that stops motor during pressure retained

  • *1 Idle stop function: A function that stops the motor once the required output pressure is obtained.

High Efficiency Standards for Electric Motors

In 2009, IE2 (high efficiency) standards were introduced to the U.S. and came into effect in Europe and China in 2013.
All countries are planning to introduce IE3 (premium efficiency) standards, and Daikin Hybrid Unit is free from Premium Efficiency Motors Regulation because the motor equipped on is the exclusive one for Inverter driven.

Daikin enables the manufacture of new oil hydraulic equipment that precisely matches the operations being sought.

Daikin offers a wide range of technology from general clamp systems to high precision oil hydraulic servo control systems.

Installation Examples

  • Machine tools (NC lathes, machining centers, honing machines, and grinders)
