Rotation; Operation; Maintenance - Xylem Goulds Water Technology 3642 Manuel D'utilisation

Alignment MUST be checked prior to running. See
Figure 6.
Tighten all hold-down bolts before checking the align-
ment.
If realignment is necessary, always move the motor.
Shim as required.
Figure 6
Parallel misalignment (shafts with axis parallel but not
concentric). Place dial indicator on one hub and rotate
this hub 360º while taking readings on the outside di-
ameter of the other hub. Parallel alignment is achieved
when reading is 0.005" (0.127 mm) TIR, or less.
Angular misalignment (shaft with axis concentric but
not parallel). Place dial indicator on one hub and
rotate this hub 360º while taking readings on the face
of the other hub. Angular alignment is achieved when
reading is 0.005" (0.127 mm) TIR, or less.
Final alignment is achieved when parallel and angular
requirements are satis ed with motor hold-down bolts
tight.
NOTICE: ALWAYS RECHECK BOTH ALIGNMENTS
AFTER MAKING ANY MECHANICAL
ADJUSTMENTS.

To reverse three phase motor rotation, interchange
any two power supply leads.

After stabili ing the system at normal operating condi-
tions, check the piping. If necessary, adjust the pipe
supports.
On frame-mounted units, coupling alignment may
have changed due to the temperature differential
between pump and motor. Recheck alignment follow-
