4.4.13 Install riser pipe, fasten power cable to
riser pipe
NOTE Not all components or sub-
assemblies of a pumping unit are
necessarily supplied by Flowserve
or part of this delivery.
These user instructions apply only
to the components or sub-
assemblies supplied by Flowserve
in this delivery, see Chapter 12.1
"Scope of delivery".
CAUTION Do not stretch the power cable and
the splices.
During the installation, observe the following pre-
cautions:
•
Support the pumping unit weight with riser
pipe elevator.
•
Keep the riser pipe centered in the well cas-
ing.
•
While lowering the riser pipe, hold the power
cable flat against the pipe and keep it from
dragging across the sharp well casing or
flange.
•
Avoid loss of power cable length.
•
Prevent rotation of the riser pipe so that the
power cable does not spiral wrap around it.
•
If used or out of round riser pipe is utilized it is
recommended to weld a steel strap across
each coupling to prevent unthreading during
start up or running.
Install the riser pipe(s)
1. Raise power cable installation wheel to 1.5
times the riser pipe length to facilitate power
cable alignment to riser pipe and well casing.
2. Arrange the random lengths of riser pipe with
their coupling ends facing one direction.
At five feet in from each pipe end, draw a
chalk mark to set the banding location.
3. Install the riser pipe.
Ensure that the flow direction is upward.
If the riser pipes are threaded:
•
Clean the mating pipe threads of the riser
pipe as shown in Figure 13, Page 30.
•
Apply thread locking fluid, e. g. Loctite
242 or DELO 5249/5349 or equivalent, to
the threads as shown in Figure 14,
Page 30.
•
Install the pipe using chain tongs (see
Figure 15, Page 31) and apply torque ac-
cording to Table 5, Page 31.
6. When the motor first enters the water, use the
surface end of the power cable to megger the
power cable and motor for ground and conti-
nuity. The reading should be 10 M
Ω or more.
If one or more vertical riser pipe check valves are
to be used on an installation, each valve, which
should have a bleed-back self draining feature, will
take the place of a riser pipe coupling.
The recommended installation is as follows:
•
One valve:
Locate the valve approximately 23 m (75 feet)
above the pump bowl assembly.
•
Two valves:
Locate the first valve 30 m (100 feet) above
the pump bowl assembly.
Locate the second valve at 3/5 of the distance
between first valve and the surface support
plate.
Fasten the power cable to the riser pipe
Use "BAND-IT" or equal stainless steel bands and
buckles to fasten the cable guard to the riser pipe.
Pull each steel band tight enough to fasten the ca-
ble guard onto the riser pipe, but do not over ten-
sion it.
Instructions for use of "BAND-IT" materials and
tools are shown in Figure 29, Page 41, to Figure
36, Page 42.
