6.2.1 Routine inspection (daily/weekly)
The following checks should be made
and the appropriate action taken to remedy any
deviations:
a)
Check operating behaviour. Ensure noise,
vibration and bearing temperatures are normal.
b) Check that there are no abnormal fluid or
lubricant leaks (static and dynamic seals) and
that any sealant systems (if fitted) are full and
operating normally.
c) Check that shaft seal leaks are within acceptable
limits.
d) Check the level and condition of oil lubricant.
On grease lubricated pumps, check running
hours since last recharge of grease or complete
grease change.
e) Check any auxiliary supplies eg heating/cooling
(if fitted) are functioning correctly.
Refer to the manuals of any associated
equipment for routine checks needed.
6.2.2 Periodic inspection (six monthly)
a) Check foundation bolts for
security of attachment and corrosion.
b) Check pump running records for hourly usage to
determine if bearing lubricant requires changing.
c) The coupling should be checked for correct
alignment and worn driving elements.
Refer to the manuals of any associated
equipment for periodic checks needed.
6.2.3 Re-lubrication
For general guidelines refer to section 5.2.5,
Lubrication schedule.
Lubricant and bearing temperature analysis can be
useful in optimizing lubricant change intervals.
6.2.4 Mechanical seals
When leakage becomes unacceptable the seal will
need replacement.
6.2.5 Gland packing
Pump must be stopped and
electrically isolated when replacing gland packing.
There is a fan above the packing, close by, on all
high temperature builds of the pump.
On hot molten salt service nitrogen is fed with three
rings of metal packing and Nitrogen will leak across the
packing for cooling purposes.
Occasionally, a new ring of packing will be required to
keep the box full.
On jacketed molten sulphur pumps the stuffing box is
normally supplied with a lantern ring to enable it to be
lubricated to the centre of the packing with the required
Molykote 44 Medium or equivalent grease from a
Staufer or equivalent.
6.3 Spare parts
6.3.1 Ordering of spares
Flowserve keeps records of all pumps that have been
supplied. When ordering spares the following
information should be quoted.
1) Pump serial number.
2) Pump size.
3) Part name – taken from section 8.
4) Part number – taken from section 8.
5) Number of parts required.
The pump size and serial number are shown on the
pump nameplate.
To ensure continued satisfactory operation,
replacement parts to the original design specification
should be obtained from Flowserve. Any change to
the original design specification (modification or use
of a non-standard part) will invalidate the pump’s
safety certification.
6.3.2 Storage of spares
Spares should be stored in a clean dry area away
from vibration. Inspection and re-treatment of
metallic surfaces (if necessary) with preservative is
recommended at 6 monthly intervals.
