Assembly / installation
BURGMANN mechanical seals are super-finished and repeatedly tested machine
elements whose handling during assembly in particular of sliding materials and
elastomers requires special care during several procedures.
For installation the assembly drawing of mechanical seal has to be observed.
IMPORTANT!
The mechanical seal has to be installed under the cleanest conditions and
very carefully.
•
Unpack the seal and check seal face, seat and elastomer bellows for possible
damages.
"
Never place the seal faces or seats on their sliding faces without having covered
them adequately.
•
Check before starting assembly:
!
complete availability of all components by means of the drawing
!
all components have to be clean and in perfect condition.
•
Sprinkle the elastomer bellows and the shaft with low-surface-tension water (add
washing up liquid) or ethyl alcohol to decrease frictional force during assembly of
the seal.
Oil or grease
as assembly agent is not permitted in any case.
ATTENTION!
Do never force
during installation.
ATTENTION! Avoid unnecessary rotation
of the shaft (damage of the sliding faces is
possible).
ATTENTION!
Avoid knocking the seal!
Damage to mechanical seals has an adverse
effect on their safe operation.
Possible installation order:
•
Feed the
degreased
sealing element (o-ring, rubber cup) onto the seat.
If present:
•
At the seat mark the position of the rear slot beside the sliding face.
•
Align the seat with the torque transmission pin.
•
Cover the sliding face of the seat with a cardboard washer
•
Press the seat slowly and without interruption into its position.
"
Use plenty of water or alcohol as lubricant.
"
Use a distance sleeve, if necessary.
•
Remove the cardboard washer from the sliding face.
•
Check the rectangular position of the seat to the shaft axis.
