THE MACHINE DOES NOT START. THE ELECTRIC MOTOR DOES NOT WORK
THE MACHINE WORKS, BUT AFTER FEW SECONDS THE MOTOR STOPS
THE GEARMOTOR IS WORKING, BUT THE SCREWS DO NOT MOVE
THE SCREENED MATERIALS ARE NOT DISCHARGED WHEN EXITING THE MACHINE
Verify the electrical grid
Wrong electrical connections
Wrong motor protection settings
Grit tension is too low, Frequency is too high
Check the grid’s conditions
Check and replace the feeding screw
The gearmotor might have sustained some
damage
Check that the gearmotor is correctly
connected with the grid and that the 3 phases’
tension is the same that the one in the plate
The shaft bearings are damaged
High percentage of solid materials in the outlet
flow
Remove the materials blocking the exit
PROBLEMS IN TERM OF PERFORMANCE AND POSSIBLE SOLUTIONS:
1- Sludge at the outlet is not dry and/or a large
quantity of sludge comes out from the drum
2- Sludge screw press stops to discharge
the dried sludge
Flocculation is not good. Please check the flocculated
sludge at the inlet of the unit. Flakes must be big and
strong enough to be squeezed by the sludge screw press.
Please check the pressure of the pneumatic
counterweight. The pressure is probably very high. Please
check the activation instructions at page 23 of the present
manual.
Please check the inlet flow. May be that SD screw press is
receiving higher flow rate higher than the maximum
capacity.
