Flottweg
Trouble shooting 4.2/2
PROBLEM CAUSE ACTION
Bowl drive motor
switches off
(overload converter)
Throughput too high Reduce throughput
Backpressure in the solids
discharge from the housing Eliminate backpressure; make sure
that discharge is ensured
(risk of motor
overloading)
Deposits in the housing slow
down the rotor Check; remove if required; adapt
rinsing measures;
Starting bearing damage in
the motor or centrifuge Replacement
(by authorised expert)
Incorrect direction of rotation
of the bowl
(at the same time, the centrate
is only discharged insufficiently
via the impeller disc)
Check; change if required; observe
the arrows showing the direction of
rotation;
in the event of wrong direction of
rotation, danger of gear and/or scroll
bearing damage
Scroll drive motor
switches off
(overload converter)
Excessive torque at the
scroll (blockage) After standstill
Switch on again at low bowl speed
(< 1000min
-1
). Discharge of solids via
the admission of water; if this measure
is not successful, disassemble and
clean (by authorised expert)
When putting the machine into
operation again, change the operating
parameters
(see ”Solids too dry“)
Bearing damage in the
motor Replacement or repair
(by authorised expert)
Damage in the gear Replacement or repair
(by authorised expert)
Controller triggers
Switching point 1
“Feed pump off“
Scroll tends to blockage;
Operating parameters are
not optimally set
(unless the
centrifuge has already reached
its performance limits)
Reduce paring diameter
Mount phase separation disc with
smaller inner diameter
Reduce bowl speed
Increase differential speed
Reduce dose of auxiliary agents
(if existent)
Controller triggers
Switching point 2
“Centrifuge off“
Scroll blocked; After standstill
Switch on again at low bowl speed
(< 1000min
-1
). Discharge of solids via
the admission of water; if this measure
is not successful, disassemble and
clean (by authorised expert)
When putting the machine into
operation again, change the operating
parameters
(see ”Solids too dry“)
