Constant-level oiler
Installation position of constant-level oiler
The constant-level oiler shall be mounted
depending on the direction of rotation as shown in
the figure above. The opposite hole shall be closed
with a plug.
Filling the constant-level oiler
Slacken the safety nut at the constant-level oiler,
draw out the oil reservoir of the constant-level oiler
and fill the reservoir of the constant-level oiler with
oil. Re-insert the oil reservoir of the constant-level
oiler and lock it.
As a general rule, oil should only
be topped up with the pump not
being in operation. Should it be unavoidable to top
up the oil of the constant-level oiler when the pump
is in operation, a temporary oil leakage might occur.
After a short time check whether
the oil level in the reservoir has
dropped. At least one third of the
reservoir must be filled with oil. If this oil level is
underrun, top up with oil.
The oil level must always be
below the vent opening arranged
at the top edge of the connection elbow! Make sure
the opening is always perfectly dry!
Oil Change Intervals
In order to ensure a long service life of the rolling
element bearings, the oil must be changed at the
following intervals:
1. Oil change after 300 operating hours
2. Oil change after 2000 operating hours
3. All subsequent oil changes after every 8000
operating hours, at least once a year.
The bearings must be cleaned thoroughly on every
oil change.
Always use clean oil!
Trouble
a) Oil reservoir empties,
oil level in the bearing housing rises.
Possible cause
Seal of oil reservoir is defective (air ingress).
b) Oil level in bearing housing falls,
no oil follows from the oil reservoir.
Possible cause
Vent opening at the connection elbow is clogged.
7.3 Dismantling
Before dismantling, secure the pump so as to
make sure it cannot be switched on accidentally.
The shut-off elements in the suction and discharge
lines must be closed. The pump must have cooled
down to ambient temperature, it must be drained
and its pressure must be released.
Dismantling and reassembly must always be
carried out in accordance with the relevant sectional
drawing.
