Servomotor for energy-efficient pressure control
With the SERVOTRON® high-pressure pump, an internal gear pump is coupled with a highly dynamic, frequency-controlled servo drive: The internal gear pump generates hydraulic pressure, which is converted into high water pressure by the intensifier and measured by a high-pressure transducer. This drive concept offers a crucial advantage: In comparison with asynchronous motors, the efficiency of this new drive concept with a frequency-controlled servo drive is approximately 15 % higher.
The operational states are measured here in the high-pressure line and passed on to the control system. This creates a control circuit which reacts directly to the required water quantity and water pressure. The motor can be accelerated to 2,700 rotations per minute in 60 milliseconds. If the cutting head is closed, the motor stops and does not consume any energy. This gives the SERVOTRON® a much higher efficiency – and an extremely energy-saving cutting process.
