Hints and instructions regarding the use in
hazardous areas
5.6 Starting
The distance between the cover and the rotating parts must be at least 5 mm.
The cover must be electrically conductive and be included in the equipotential bonding. Bellhousings made from
aluminium and damping rings (NBR) can be used as connecting element between pump and electro motor if the
magnesium part is below 7,5 %. The cover may only be taken off after having stopped the unit.
During operation, please pay attention to
•
strange running noises
•
occurring vibrations.
!
C A U T I O N !
If you note any irregularities at the coupling during operation, the drive unit must be turned
off immediately. The cause of the breakdown must be found out with the table
„Breakdowns“ and, if possible, be eliminated according to the proposals. The possible
breakdowns mentioned can be hints only. To find out the cause all operating factors and
machine components must be considered.
5.7 Breakdowns, Causes and Elimination
breakdowns causes
danger hints for
hazardous areas
elimination
misalignment
friction at the
toothing of the
elastomer part
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) eliminate the reason for the
misalignment (e. g. loose foundation
bolts, break of the engine fixing, heat
expansion of unit components, change
of the assembly dimension E of the
coupling)
3) checking of wear see under point
Control
change of the
running noises
and / or occurring
vibrations
loose screws for
axial securement of
hubs
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) check alignment of coupling
3) tighten the screws to secure the hubs
and secure against self-loosening
4) checking of wear see under point
Control
break of the
elastomer part /
toothing due to
overload
---
1) put the unit out of operation
2) disassemble the coupling and remove
rests of the elastomer part
3) check coupling parts and exchange
damaged coupling parts
4) insert elastomer part, assemble coupling
parts
5) find out the reason of overload
break of the
elastomer part
operating
parameters do not
correspond to the
performance of the
coupling
---
1) put the unit out of operation
2) check the operating parameters and
select a larger coupling (consider
installation space)
3) assemble new coupling size
4) check alignment
