MAINTENANCE AND INSPECTION
13.1 GEARBOX AND MOTOR
The gearbox and motor are delivered ready for operation. They are filled with the required volume of oil
and
maintenance-free
. After approx. 10,000 operating hours, but no later than every 2 years, the oil
must be changed and the bearing inspected; details on this work can be found in the gearbox and motor
documentation.
Perform a daily visual inspection during operation to ensure that the seals of the gearbox and machine
are tight.
Check the oil level of the gearbox roughly twice per year. Other than a regular supply of sealing medium,
the FAN press screw separator normally requires little maintenance.
13.1.1
Supply of Sealing Medium
NOTE
When using sealing media and grease it must be guaranteed that they are compat-
ible with the seals (material FPM). As a rule grease of viscosity class 2 is used
such as Alvania EP 2 from Shell, Beacon EP 2 from Esso or Aralub HLP 2 from Aral.
On a separator in operation, it is important to supply seal-
ing medium to the blocking seal, in the flange of the in-
flow housing, in order to protect the seals from the medi-
um being separated.
This can be accomplished with sealing grease
.
For this purpose, a grease
press must be used
every 125
operating hours or weekly
to
introduce roughly 3 to
5 cm
3
of
grease via the lubricating
nipple
.
The grease should be supplied while the machine is run-
ning to ensure that the entire seal area is filled with seal-
ing medium. The use of an automatic lubricator is even
better. Lubricate the other lubricating nipples on the
geared motor 1x per year.
To safeguard the function of the seal, check the inspec-
tion opening on the bottom of the flange of inflow hous-
ing. If sealing medium, water or foreign substances es-
cape here, the blocking seal is damaged or worn and
must be replaced. If the blocking seal is not replaced, the
supply medium can clog the inspection window over time
and also damage the second seal, allowing the medium
to damage the bearing and/or the
gearbox
. It is there-
fore very important to regularly check the inspection
opening on the bottom of the flange of inflow housing. No
medium should escape from this opening; otherwise, the
blocking seal is damaged and must be replaced.
