Fig. 17: Pump set with shim
1 Shim
✓ Misalignment of the coupling (⇨ Section 5.6.1 Page 30).
✓ The coupling guard and step guard, if any, have been removed.
1.
Unscrew the hexagon head bolts at the motor.
2. Insert shims (1) underneath the motor feet until the difference in shaft centre
height has been compensated.
3. Re-tighten the hexagon head bolts.
4. Check that the coupling and shaft can easily be rotated by hand.
Check that coupling/shaft can easily be rotated by hand.
WARNING
Unprotected rotating coupling
Risk of injury by rotating shafts!
▷ Always operate the pump set with a coupling guard.
If the customer specifically requests not to include a coupling guard in KSB's
delivery, then the operator must supply one!
▷ Observe all relevant regulations for selecting a coupling guard.
DANGER
Risk of ignition by frictional sparks
Explosion hazard
!
▷ Choose a coupling guard material that is non-sparking in the event of
mechanical contact (see DIN EN 13463-1).
5. Reinstall the coupling guard and step guard, if any.
6.
Check the distance between coupling and coupling guard.
The coupling guard must not touch the coupling.
5.7.3 Pump sets with belt drive
CAUTION
Incorrect tension
Insufficient power transmission! Increased wear of the V-belt!
▷ Always ensure correct tensioning of the V-belt.
✓ The belt guard has been removed.
✓ The tension of the V-belts is too low or too high (⇨ Section 5.6.2.4 Page 32)..
1.
Move motor bracket 81-54.01 up or down by turning threaded rods
904.23/904.24 until the V-belt is tensioned correctly.
Tension forces (⇨ Section 5.6.2.4 Page 32)
2. Check the tension of the V-belt with a belt tension measuring tool (measuring
tool not included in the scope of supply).
3. Check the tension again between ½ hour and 1 hour after initial operation.
