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.
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.
c)Use grouting products with
d)To grout up to the required level. Polish surfaces. Take necessary precautions to avoid air bubbles.
e)
f)After grout starts to cure, definitively tighten anchor bolts.
g)Control the alignment such as described as follows.
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 |
4.4 Initial alignment
The alignment will be definitive only
Before connecting the couplingsafter pipework connection (see § 4.5.1). verify the motor rotation direction.
