9 Maintenance
The torsionally rigid disk coupling POSIMIN
®
-PHP does not need maintenance during opera-
tion.
On the occasion of routine inspections or maintenance of the equipment, check:
•
alignment of coupling
•
state of disk packs
•
firm fit of all fastening elements
•
lost parts
•
remove dust deposits from coupling parts and disk packs.
9.1 Disk Pack Inspection
§
Danger of injuries!
§
Disconnect the drive before carrying out any work on the
coupling!
§
Secure the drive against unintentional re-start and rotating!
•
Visually inspect the disk packs after 2000 hours, however after 3 months at latest, after
the first start-up. If this first inspection does not reveal any damages such as cracks or
dents on the disks, further inspections may be conducted at regular intervals of 4000
hours, however, at least once a year, provided that the operation modes and service con-
ditions of the equipment are not altered.
•
If damages of the disk packs are already detected on the occasion of this first inspection,
verify whether the cause for the problem is listed in table 5 “Operation faults”. It is essen-
tial to adapt the inspection intervals to the prevailing operation conditions.
•
Under special operation conditions it may be necessary to perform inspections and main-
tenance operations at shorter intervals than stated.
