9.2 Check-list in case of fault
If you have been unable to solve the problem on the equipment (machine) even after having carried out
the operations suggested in paragraph “Trouble-shooting” please contact the plant technician/installer/or the
Manufacturer.
If technical assistance is required, in addition to the equipment data, the plant technician/installer or Manufac-
turer will also need information concerning the plant in which the equipment (machine) is installed, its installa-
tion and its working, for better identification of the problem that has occurred.
Obviously many of the checking operations which are requested have already been performed in the various
steps during installation, testing and start-up of the equipment (machine) concerned.
Danger - Warning
Before carrying out any operation “set the equipment (machine) concerned in safety” (see “Glossary
and terminology”), operate according to the indications on the “Operation and Maintenance Manual”
and in accordance with and in compliance with the standards in force as regards health and safety.
1) Information necessary
a)
Description of the problem
b)
Total working hours
c)
Running frequency (hours per day or month)
d)
Photo of the separator
e)
Picture of the plant and of all connecting pipes up to the collecting tanks / or similar lagoons.
f)
Video, if possible, that allows listening the noise of the separator while running and controlling the output of
solid, liquid drain and overflow discharge.
g)
Motor absorption.
h)
Material level at the overflow.
2) Checking the electrical parts
a)
Are voltage variations possible due to simultaneous start-up of various pieces of equipment?
b)
Is the plant equipped with a power generator?
c)
The thermal protection of the electric motor inside the panel has delayed action. Is its adjustment in line with
the data on the motor rating plate?
d)
Check the power input of the motor without load, at breakaway current and when the screw pump is operat-
ing at full speed!
3) Checking the separator
a)
Has the separator been assembled correctly?
b)
Has the separator been fixed properly?
c)
Have the pipes been connected properly with no bottlenecks?
4) Checking the material to be handled
a)
Description of the process the material undergoes before reaching the separator
b)
Define the nature of the material
c)
What is the percentage dry matter at inlet?
d)
Is there a system for mixing the material in the tank upstream the separator?
