5.1.3.2 Pure Oil Mist
In this method all oil is drained from the oil sump, this
is sometimes referred to as a dry sump. Oil is
injected outboard at each bearing. To use this
method some modifications must be made to the
pump. If pumps are shipped for standard oil or
grease lubrication the pumps must be dismantled
and reworked. All oil return grooves that permit
movement of oil from outboard of each bearing back
to the sump must be block. These passages may be
blocked using epoxy filler or other compounds
compatible with the mist oil. Pressure inside the
center of the bearing frame must be controlled to
25mm (1”) H
2
O or less. Pressures greater than this
may result in excessive venting of oil through
outboard seals and could result in bearing failure as
mist is not forced through the bearing. It is
recommended that mist system operate for 24 hrs
before starting of the pump to ensure bearing
surfaces have been properly misted. Testing
completed has used an oil viscosity of 100 Cst. For
additional information refer to TR-3326, Pure Oil Mist
lubrication of FRBH and R/M Slurry Pumps. Thrust
bearings on frame 4 pumps to be changed to angular
contact ball Bearings. Oil mist not recommended for
frame 5&6 pumps.
