Daikin Super-Unit (Inverter Hydraulic Unit)

1) The high-efficiency IPM motor drive system that utilizes the DAIKIN original air conditioning motor and inverter technologies provides a high energy-saving ratio-50%.

• By controlling the motor rotation speed, the SUPER UNIT controls the flow rate and pressure of fixed-capacity pumps. This system provides an energy-saving ratio is at least 50% in pressure-holding mode (compared with the conventional DAIKIN variable piston pump).
• Using the high-efficiency motor, the SUPER UNIT can even provide an energy-saving effect for general industrial machinery in which actuators provide a high duty ratio, as well as in pressure-holding mode.
• The single pump type is a highly-functional series created to be more useful.
• The double pump type uses the autonomously-switching, fixed-capacity double pump system, which combines large-and small-capacity pumps in a low pressure, high flow rate range, and autonomously switches to operate the high-pressure, small capacity pump only in the high pressure, low flow rate ranges. Thus, the double pump type ensures a higher energy-saving effect.

2) Four or sixteen pressure - flow rate setting patterns are available for cylinder control.

• The proportional control valve and proportional pressure control valve, which are utilized in the conventional actuator circuits, are not required.
• The pressure and flow rate can be set using the controller panel.
• You can select 4 or 16 pressure and flow rate setting patterns via an external input signal.
• The SUPER UNIT autonomously switches between the pressure control and flow rate control modes.
• --> Reducing shock during flow rate or pressure changes
• Depending on the acceleration time/deceleration time settings, the SUPER UNIT can reduce shock when the flow rate or pressure is changed.

3) Low noise level

• With double phase-differential pumps, the SUPER UNIT can reduce pulsation and the noise level.

4) Multi-stage P-Q remote control by communication

• Using a commercially-available PLC with RS-232C communication capabilites and a touch panel display, P and Q parameters, acceleration time, deceleration time, and other parameters can be set and viewed from the machine operator's side. The SUPER UNIT enables multi-stage pressure/flow rate control through remote operation.

5) The SUT series product lineup contains producrs with various capacities, from 7.0 MPa and 1.5 L/min to 20.6 MPa and 110 L/min. Furthermore, "pump & motor type" and "unit type" are selectable. Thus, the SUPER UNIT can flexibility meet almost any user's needs.

• The SUPER UNIT offers wide applications for machine tools and general industrial machinery such as press.
