Flottweg-SIMP-CONTROL®
2. Control of the scroll drive
The below listed features of the controller apply irrespective of its model, e.g. as
industrial controller or software component of a control programme.
2.1 Operating modes, function and selection
In the operating mode Manual operation, the differential speed (output signal Y) is set
directly by the operator and remains constantly at the stipulated value. The display of the
scroll torque is only for information purposes.
In the operating mode Automatic operation, the scroll torque (controlled variable X) is
adjusted to the nominal torque value (W) set by the operator.
The controller responds to a scroll torque exceeding the nominal value by increasing the
differential speed (output signal Y). Thus, more solids is transported from the centrifuge
and the torque decreases. If the torque drops below the nominal value, the differential
speed is reduced again.
The selection of the optimum operating mode depends on the properties of the
product, consequently this is only a recommendation.
Manual:
“Soft products” where a differential speed change hardly causes any torque change.
Typical here is a relatively low torque over a wide differential speed range.
Automatic:
Compacting product where there is an obvious connection between differential
speed change and torque change. Typical are high torques, primarily at low
differential speeds.
