SECTION E: PREVENTATIVE MAINTENANCE
As the motor is oil filled, no lubrication or other maintenance
is required, and generally Barnes Pumps will give very
reliable service and can be expected to operate for years on
normal sewage pumping without failing. However as with any
mechanical piece of equipment a preventive maintenance
program is recommended and suggested to include the
following checks:
1) Inspect motor chamber for oil level and contamination
and repair as required per section F-1.
2) Inspect impeller and body for excessive build-up or
clogging and repair as required per section F-2.
3) Inspect motor and bearings and replace as required
per section F-3.
4) Inspect seal for wear or leakage and repair as required
per section F-4.
SECTION F: SERVICE AND REPAIR
NOTE: All item numbers in ( ) refer to Figures 15 thru 18.
F-1) Lubrication:
Anytime the pump is removed from operation, the cooling oil
in the motor housing (6) should be checked visually for oil
level and contamination.
F-1.1) Checking Oil:
Motor Housing-
To check oil, set unit upright. Remove pipe
plug (39) from motor housing (6). With a flashlight, visually
inspect the oil in the motor housing (6) to make sure it is clean
and clear, light amber in color and free from suspended
particles. Milky white oil indicates the presence of water. Oil
level should be just above the motor when pump is in vertical
position.
F-1.2) Testing Oil:
1.)
Place pump on it’s side, remove pipe plug (39), from
motor housing (6) and drain oil into a clean, dry container.
2.) Check oil for contamination using an oil tester with a
range to 30 Kilovolts breakdown.
3.) If oil is found to be clean and uncontaminated
(measuring above 15 KV. breakdown), refill the motor
housing as per section F-1.4.
4.) If oil is found to be dirty or contaminated (or measures
below 15 KV. breakdown), the the pump must be
carefully inspected for leaks at the shaft seal (28), cable
assemblies (16) and (56 if used), square ring (27) and
pipe plug (39), before refilling with oil. To locate the
leak, perform a pressure test as per section F-1.3.
After leak is repaired, dispose of old oil properly, and
refill with new oil as per section F-1.4.
SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase
information stamped on the pump identification plate to the
available power.
D-2) Check Pump Rotation:
Before putting pump into service for the first time, the motor
rotation must be checked. Improper motor rotation can result in
poor pump performance and can damage the motor and/or
pump. To check the rotation, suspend the pump freely,
momentarily apply power and observe the "kickback".
"Kickback" should always be in a counter-clockwise direction as
viewed from the top of the pump motor housing.
D-2.1) Incorrect Rotation for Three-Phase Pumps:
In the event that the rotation is incorrect for a three-phase
installation, interchange any two power cable leads at the control
box.
DO NOT change leads in the cable housing in the motor.
Recheck the "kickback" rotation again by momentarily applying
power.
D-2.2) Incorrect Rotation for Single-Phase Pumps:
In the unlikely event that the rotation is incorrect for a single
phase pump, contact a Barnes Pumps Service Center.
D-3) Start-Up Report:
Included at the end of this manual are two start-up report sheets,
these sheets are to be completed as applicable. Return one
copy to Barnes Pumps, Inc. and store the second in the control
panel or with the pump manual if no control panel is used. It is
important to record this data at initial start-up since it will be
useful to refer to should servicing the pump be required in the
future.
D-3.1) Identification Plate:
Record the numbers from the pump identification plate on both
START-UP REPORTS provided at the end of the manual for
future reference.
D-3.2) Insulation Test:
Before the pump is put into service, an insulation (megger) test
should be performed on the motor. The resistance values
(ohms) as well as the voltage (volts) and current (amps) should
be recorded on the start-up report.
D-3.3) Pump-Down Test:
After the pump has been properly wired and lowered into the
basin, sump or lift station, it is advisable to check the system by
filling with liquid and allowing the pump to operate through its
pumping cycle. The time needed to empty the system, or
pump-down time along with the volume of water, should be
recorded on the start-up report.
