Maintenance - OLI MVE J Serie Handbuch

MVE
C
Follow the standards relating to connections and the use of electrical equipment in potentially
explosive atmospheres. The motovibrators must be handled, installed, put into service, inspected,
maintained, repaired and, if necessary, dismantled only by qualified and trained personnel in
accordance with the above regulations. These operations must always be carried out in the
absence of potentially explosive atmospheres.
Before carrying out any maintenance work, ensure the electric motovibrator and the equipment
to which it is connected are safe.
MAINTENANCE MUST BE CARRIED OUT BY QUALIFIED PERSONNEL ONLY AND WITH THE POWER
OFF.
Before performing any work, check that the temperature of the motovibrator does not exceed 55°C.
SPECIAL FEATURES
The machine is set up for the equipotential connection to the earthing network.
LUBRICATION
All OLI motovibrators can be fitted with ball or roller bearings, depending on their size.
The ball bearings are shielded and pre-lubricated by the manufacturer of the bearings themselves.
The roller bearings are instead pre-lubricated by OLI with specific grease, suitable to guarantee adequate lubrication for a number of hours
that at least covers the service life of the bearing itself (specified for each model in the TAB section from page TAB.166 to TAB.173).
This is why no motovibrator requires periodic lubrication.
Vibrators with roller bearings can be recognised by the sticker placed on the exposed conductive part covers reading "DO NOT GREASE
LIFETIME LUBRICATION".
Motovibrators with roller bearings are delivered with lubrication channels that can be accessed from the outside, but closed by threaded
screws.
If using the "periodic relubrication" method, this must be carried out every 3000 hours of operation by inserting special M6 lubricators into
the above channels instead of the screws. The amount of grease required is specified in the TAB section from page TAB.166 to TAB.173
Only use this kind of grease: MOBILITH SHC 100.
Do not mix different types of grease, even if they have similar characteristics.
At the end of the service life of the OLI bearing, it is advisable to replace both the bearing and the grease.
To remove the bearings, refer to the "REPLACING THE BEARINGS" paragraph.
Only use this kind of grease: MOBILITH SHC 100.
Remove spent grease from the flanges. Install the new bearing and apply the new grease in the amounts specified in the TAB section from
page TAB.166 to TAB.173.
Let the grease penetrate into rolling parts, paying great attention to ensure no impurities are introduced. The presence of residues or
impurities can damage the bearing while reducing its service life.
REPLACING THE BEARINGS
THE REPLACEMENT MUST BE CARRIED OUT ON A BENCH BY QUALIFIED PERSONNEL ONLY AND
WITH THE POWER OFF.
- Power off the motovibrator.
- Disassemble the motovibrator and place it on the bench.
- Remove the side covers.
- Remove the eccentric exposed conductive parts.
- Remove the bearing-holder flanges through the threaded extraction holes.
- Remove the bearing with the designated extractor.
- Take out the bush from the shaft.
- Replace the bearing.
- Reassemble the vibrator.
During the reassembly stage, maintain the parts perfectly at right angles, avoiding shifts that could irreparably damage the bearings and
bearing-holder flanges. Ensure the screws, washers and gaskets are not damaged.
If so, replace them.
