TPC 305 PUMP CORRECT FINALS QUESTIONS AND
ANSWERS SURE A+
✔✔Sodium soap greases - ✔✔Don't work well around water
✔✔Lithium soap greases - ✔✔Handle extremes of temperature well and resist water
✔✔Non soap based greases - ✔✔Complex is a complicated organic molecule that traps
metal ions in a lattice of atoms
✔✔Usual percentage of oil in greases - ✔✔70 to 90%
✔✔Grease Additives - ✔✔Keep the grease from undergoing chemical changes
✔✔Extreme pressure greases - ✔✔High film strength
✔✔Special load carrying additives to lithium soap greases - ✔✔Various sulfurized oils
✔✔Lamellar greases - ✔✔Effectiveness of a grease type lubricant can also depend on
the physical shape of the solid additive particles
✔✔Silicone greases - ✔✔Special synthetic liquid. Silicone is a compound polymer.
Soap or nonsoap types
✔✔Dry film lubricants - ✔✔Most dry films are applied the same way as ordinary paints
✔✔Lubricant delivery - ✔✔One aspect is the regulation of the lubricant
✔✔Gravity lubrication - ✔✔Frequently called drip-feed oiling
✔✔Natural Lubrication - ✔✔A portion of the machine housing is used as an oil sump
, ✔✔Wick or pad absorbent material - ✔✔In addition a number of lubricating devices use
saturated pads
✔✔Oil mist lubricator - ✔✔The pump will probably be a gear type pump
✔✔Oil mist - ✔✔It handles larger quantities of oil and operates on very low pressure air
and uses centrifuging to mechanically reclaim oil
✔✔Oil Lubrication pumps - ✔✔Increase pressure and meter the oil. Check valve and
direct lubrication system
✔✔Parallel tube - ✔✔Indicates flow but not rate
✔✔Flow indicators - ✔✔Higher pressure systems installed on intake or suction side
✔✔Header systems - ✔✔Control valve on discharge side reverses flow
✔✔Single line metering - ✔✔Slide valve
✔✔Progressive metering - ✔✔Centralized lubrication
✔✔When lubricants are stored outside, both weather and the specific plant ... must be
considered - ✔✔Environment
✔✔Grease introduced into systems - ✔✔At room temperature
✔✔Purification and Reclamation - ✔✔While in service- full flow filtration or separation
✔✔Centrifuges - ✔✔Separate the water and oil, disks or dams guide them
✔✔Absorbent filters - ✔✔Sintered metal used for final filtering .5 to 2 microns
✔✔Lubrication control - ✔✔ID number or asset number or sequence number
✔✔Anti friction bearings - ✔✔Less power demand because low starting friction is
required
✔✔Journal bearings - ✔✔Radial load and motion confinement
✔✔Thrust bearing - ✔✔Axial load and lateral motion confinement
✔✔Bending stress - ✔✔Spotty, uneven wear especially in sleeve bearings
