4.7 Electrical connections
Electrical connections must be made by
a qualified Electrician in accordance with relevant
local national and international regulations.
It is important to be aware of the EUROPEAN
DIRECTIVE on potentially explosive areas where
compliance with IEC60079-14 is an additional
requirement for making electrical connections.
It is important to be aware of the EUROPEAN
DIRECTIVE on electromagnetic compatibility when
wiring up and installing equipment on site.
Attention must be paid to ensure that the techniques
used during wiring/installation do not increase
electromagnetic emissions or decrease the
electromagnetic immunity of the equipment, wiring or
any connected devices. If in any doubt contact
Flowserve for advice.
The motor must be wired up in
accordance with the motor manufacturer's
instructions (normally supplied within the terminal
box) including any temperature, earth leakage,
current and other protective devices as appropriate.
The identification nameplate should be checked to
ensure the power supply is appropriate.
See section 5.4, Direction of rotation
before connecting the motor to the electrical supply.
4.8 Final shaft alignment check
4.8.1 Horizontal pumps
a) Level baseplate if appropriate.
b) Mount and level pump if appropriate. Level the
pump by putting a level on the discharge flange.
If not level, adjust the footpiece as follows:
Mark 3A and ANSI 3 design
Add or delete shims [109A] between the
footpiece and the bearing housing.
Mark 3 design
Use the adjuster nut [6570.4B] to adjust the
footpiece up or down.
c) Check initial alignment. If pump and driver have
been remounted or the specifications given below
are not met, perform an initial alignment as
described in section 4.5. This ensures there will
be sufficient clearance between the motor hold
down bolts and motor foot holes to move the
motor into final alignment. The pump and driver
should be within 0.38 mm (0.015 in.) FIM (full
indicator movement) parallel, and 0.0025 mm/mm
(0.0025 in./in.) FIM angular.
Stilt mounted baseplates
If initial alignment cannot be achieved with the
motor fasteners centered, the baseplate may be
twisted. Slightly adjust (one turn of the adjusting
nut) the stilts at the driver end of the baseplate and
check for alignment to the above tolerances.
Repeat as necessary while maintaining a level
condition as measured from the pump discharge
flange.
d) Run piping to the suction and discharge to the
pump. There should be no piping loads
transmitted to the pump after connection is made.
Recheck the alignment to verify that there are no
significant changes.
e) Perform final alignment. Check for soft-foot under
the driver. An indicator placed on the coupling,
reading in the vertical direction, should not indicate
more than 0.05 mm (0.002 in.) movement when
any driver fastener is loosened. Align the driver
first in the vertical direction by shimming
underneath its feet.
f) When satisfactory alignment is obtained the
number of shims in the pack should be minimized.
It is recommended that no more than five shims be
used under any foot. Final horizontal alignment is
made by moving the driver. Maximum pump
reliability is obtained by having near perfect
alignment. Flowserve recommends no more than
0.05 mm (0.002 in.) parallel, and 0.0005 mm/mm
(0.0005 in./in.) angular misalignment. (See
section 6.8.7.2.)
