A guide for stuffing box inspection is provided in Table 16.
6.5.1.3
Sealing Water Systems. Make the daily checks for the sealing water
system that are listed in Table 14. If the leakage cannot be adjusted properly, repack
the stuffing box according to par. 6.5.1.2 and Table 16. Each year, disassemble the
sealing water lines and valves to make sure that the water passages are open.
6.5.1.4
Rotary Seals. If a pump has seals that do not have the conventional
follower and pliable, replaceable packing, consult the manufacturer's manual.
6.5.1.5
Shafts and Shaft Sleeves. Each year, when the pump is dismantled,
examine the shaft carefully at the impeller hub, under the shaft sleeves, and at the
a)
Shafts. The shaft may be damaged by rusting or pitting caused by
leakage along the shaft at the impeller or shaft sleeves. If antifriction bearings are
improperly fitted to the pump shaft, the inner race rotates on the pump shaft and
damages the shaft. Excessive thermal stresses or corrosion may loosen the impeller
on the shaft and subject the keyway to shock. Replace any shaft that is bent or
distorted. After the shaft has been replaced, check it for possible runout. The
maximum allowable is 0.002 inches (51 microns []).
