Lubricant Programs Flashcards
What should be the primary source of lubrication recommendations?
The OEM recommendation in conjunction with the lubricating oil supplier.
What steps should be taken when changing lubricant suppliers?
Follow OEM recommendations for each machine
Consolidate lubricants where possible
Test competitive products for compatibility, or flush thoroughly
Analyze new oil to establish a base line
What seven items should be listed on a lubrication survey?
Department (and/or location Equipment (components and lube points) Lubricant Amount Frequency Method Comments
Specifications for lubricants should be developed as a cooperative effort between what groups of people in a company that uses lubricants?
Purchasing
Maintenance Engineer
Plant engineer
Define “Root Cause” and how it applies to lubrication.
The primary reason for failure in a chain of events. Root cause analysis can prevent further failures by correcting the source rather than the symptoms of an event.
Define Failure Mode and how it applies to lubrication.
It is the sequence of events that lead to failure.
What are the 12 most common lubrication errors?
Wrong lubrication Water
Quantity Air
Viscosity Particulates
Amount Failure to assign lubrication to one person
Properties To adequately survey
Temperature To keep adequate records
Flow rate To investigate all mechanical malfunctions
Contaminations with another lubricant
To prevent unauthorized personnel from lubricating equipment
To updated and refine lubrication program
How might you determine if an oil change interval could be extended?
Oil analysis - viscosity Total acid number Spectrographic analysis Operating history In engines, look at oil consumption and fuel consumption
List five different application intervals that might be listed on a lubrication survey.
Weekly Monthly Yearly As required daily Every shift
What are the components of an oil mist system?
Oil reservoir air supply mist generator heater manifold piping reclassifier
What are the major differences between air mist and airline oiler systems.
Misted oil is reclassified, collected, and reused. Airline oilers push oil to the application and is a once through, not reused.
What is the generic name for an automatic lubricator?
Trabon
Where do you lubricate a roller chain? By what method?
Pin links and roller links. Apply to lower strand before sprocket gear. Brush, oil can, bath, spray, singer, drip, mist.
In a high loss system, what can be installed to help monitor oil consumption?
Oil level indicators, pump meter on dispensing equipment, inventory records.
What are the disadvantages of oil mist lubrication?
Difficult to set flow rates, environmental concern (stray mist), sensitive to temperature changes, high cost of installation.
What are the disadvantages of oil mist lubrication?
Difficult to set flow rates, environmental concern (stray mist), sensitive to temperature changes, high cost of installation.
______________ lubrication commonly saves lubricant, saves energy, and improves reliability where such systems can be used.
Mist
The principle of oil mist operation is based on the ability of oil particles to be ________________ by impact on a surface at high velocity.
Reclassified
What are some advantages of oil mist lubrication?
Constant supply of fresh lubricant Slight pressurization reduces contamination, No moving parts, Alarm systems monitor flow and oil level, Low lubricant consumption, Lower bearing temperatures due to lower internal friction, Prevents moisture intrusion.
What are ten extra costs incurred when high oil losses are tolerated?
- Cost of replacement lubricant 2. Cost of catching the spilled lubricant 3. Waste oil disposal cost 4. Environmental cost 5. Cost of in-plant transfer and resulting empty drums 6. Extra drum disposal cost 7. Temptation to switch to cheaper lubricant 8. Extra labor involved to maintain oil level 9. Shorter equipment life due to poor in service maintenance 10. Shorter equipment life due to lubricant starvation 11. Substitution of product due to emergency fill operation 12. Housekeeping costs.
What are three reasons why bulk packaging reduces costs?
Reduced transportation costs reduced repackaging (labor) lower disposal costs potential for discounts minimizes storage reduces inventory
Above ground oil storage tanks should have _________ to contain spills.
Dikes
Name four financial justifications for purchasing a new lubrication system such as an automatic dispensing system.
Reduces lubricant consumption, longer equipment life, reduced maintenance, reduced contamination.
List five goals of an oil conservation management program.
Reduce volume used segregate used oils reprocess used oils minimize wastewater contamination minimize environmental impact
