We provide energy-saving solutions along with other benefits in Die-casting foundries with Baumuller Servo hydraulic systems.
- Complete servo-hydraulic system
It consists servo motor, gear pump & servo drive with an integrated “servo-hydraulics” technology package, along with necessary components I.e. control panel, line filter, brake resistors, line choke, bell hosing, coupling and cables for motor & Encoder. It is cost-effective for GDC, LPDC and lower tonnage HPDC machines.
2. Servo drive panels
It consists servo drive with necessary components i.e. line filter, line choke, brake resistors, encoder for motor & cables. This can be implemented without any hydraulic changes in the machine, as the motor & pump will be as it is. It will give fewer benefits compared to a servo-hydraulic system due to the limitation on induction motor minimum speed.
We can also supply servo drive & motors for linear motion control as per customer requirements.
Advantages of the servo-hydraulic system
- Electrical energy saving 60-70 % in GDC and LPDC and 25-50 % in HPDC machines.
- Reduces Hydraulic fluid temperature, as no flow during unloading or no operation conditions.
- Longer hydraulic components life due to less heating.
- Smooth and flexible change-over between pressure-and volume control
- Pressure control in 125μs-loop
- Very low pulsation of pressure and flow rate, So Excellent control behaviour and improved process quality.
- Flow & Pressure control proportional valves are not required, as it is controlled by a servo system.
- Operating cost is low.
