Hints and instructions regarding the use in
hazardous areas
5.8 Breakdowns, Causes and Elimination
Continuation:
•
No original KTR parts (purchased parts) are used.
•
The coupling used/the coupling protection used is not suitable for the operation in hazardous areas and does
not correspond to EC Standard 94/9/EC, respectively.
•
Maintenance intervals are not observed.
Breakdowns
Causes
Danger hints for
hazardous areas
Elimination
Change of the
running noises
and / or occurring
vibrations
Misalignment
---
1) 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
Loose shoulder
bolts, low micro
friction under the
screw head and at
the steel laminae
package
Danger of ignition due
to hot surfaces
1) Put the unit out of operation
2) Check coupling parts and exchange
damaged coupling parts
3) Tighten the shoulder bolts until
reaching the permissible tightening
torque
4) Check alignment, correct if necessary
Loose screws for
axial securement of
flange hubs
---
1) Put the unit out of operation
2) Check alignment of coupling
3) Tighten the screws to secure the flange
hubs and secure against self-loosening
4) Checking of wear see under point
Control
Break of the steel
laminae package
Break of the steel
laminae package
due to high shock
energy / overload
Danger of ignition due
to sparking
1) Put the unit out of operation
2) Disassemble the coupling and remove
the rests of the steel laminae packages
3) Check coupling parts and exchange
damaged coupling parts
4) Insert steel laminae packages,
assemble coupling parts
5) Find out the reason of overload
Operating
parameters do not
correspond to the
performance of the
coupling
Danger of ignition due
to sparking
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
