11.1.2 After first month of operation
Check spray valves for foreign matter, which may have accumulated from new piping.
Clean if necessary.
11.1.3 Semi-Annually
11.1.3.1 Inspect spray valves and preheater section for scale or dirt (thin scale
formations will not affect efficiency). Remove any accumulation of debris or scale if
necessary.
11.1.3.2 Clean oil separator trap if employed.
11.1.3.3 Inspect relief valve and vacuum breaker for proper operation.
11.1.4 Annually
11.1.4 1 Drain storage section and remove manhole. Flush out all sediment in storage
section and follow with manual cleaning, if necessary. Make certain pump suction
openings and piping are clean.
11.1.4.2 Inspect scrubber section. Flush out sediment through scrubber drain.
11.1.5 Frequently
Check deaerator gauge glasses frequently for the presence of oil. Oil is more damaging
than scale in a boiler. If detected, immediate steps must be taken to find its source an
eliminate it (Refer Section 12.0-Troubleshooting). After the cause has been found and
rectified, the deaerator should be drained and thoroughly cleaned before being
returned to service.
11.2 Pumps
11.2.1 Packing
Check packing glands – DO NOT run dry. Permit a few drops of water per minute to
drop from glands. This provides lubrication for the shaft, eliminating burned packing
and scored shafts. When tightening gland bolts, do so ONLY when pump is running.
Draw up evenly 1/4 turn at a time to allow gland pressure to equalize throughout
stuffing box.
Replace with Hi-temp packing after six (6) months to one (1) year, depending upon
severity of service. Remove all old packing first (do not intermix new and old packing).
Insert individual rings so that splices are staggered. When stuffing box is full, adjust
gland just tight enough to permit slight leakage as described above – DO NOT RUN DRY.
11.2.2 Bearings
These will require periodic lubrication, using the grease fittings in the pump frame. For
8 hours daily operation, this should be every thousand hours. Use ball bearing grease of
high quality; lithium, lithium soda or calcium base grease is recommended for both wet
and dry locations. Do not mix different brands.
Avoid over lubrication, which can result in overheating and bearing failure. Adequate
lubrication is assured if grease quantity is maintained at to the capacity of the bearing.
Approximately every six (6) months, bearing should be cleaned by flushing with kerosene
and relubricated.
