4.3 Grouting
4.3.1 Base plate grouting
a) Prepare the site for grouting. Before grouting
clean the foundation surface thoroughly and
provide external barriers as shown:
Barriers
b) Prepare grouting product (concrete, resin) in
accordance with manufacturers' instructions.
c) Use grouting products with anti-shrinking
components.
d) To grout up to the required level. Polish
surfaces. Take necessary precautions to avoid
air bubbles.
e) Lay-down the barrier, break external angles, and
polish the different surfaces.
f) After grout starts to cure, definitively tighten
anchor bolts.
g) Control the alignment such as described as
follows.
4.4 Initial alignment
Before connecting the couplings
verify the motor rotation direction.
4.4.1 Thermal expansion
The pump and motor will normally
have to be aligned at ambient temperature and
should be corrected to allow for thermal expansion
at operating temperature. In pump installations
involving high liquid temperatures, the unit should be
run at the actual operating temperature, shut down
and the alignment checked immediately.
4.4.2 Alignment methods
Ensure pump and driver are isolated
electrically and the half couplings are disconnected.
Ensure that the pump pipework, suction and
discharge, is disconnected.
The alignment MUST be checked.
Although the pump will have been aligned at the
factory it is most likely that this alignment will have
been disturbed during transportation or handling. If
necessary, align the motor to the pump, not the
pump to the motor.
Alignment
Parallelism and concentricity check:
Check the alignment at three or four
points, before pipeworks assembly.
with a rule with a comparator
Admissible margin for a motor with roller bearings:
= 0.15 mm parallel checking
= 0.1 mm angular checking
Angular checking:
with a sliding rule with a caliper gauge
The alignment will be definitive only
after pipework connection (see § 4.5.1).
