Lubrication - Lubricating Oils and Additives
Edward Brunet, Jr., P.E.
Overview
Lubricating oils are used in machinery to reduce friction
between two surfaces in contact. The improper selection of a lubricant can
result in wasted energy due to heat loss and premature wear of parts.
Lubricating oils are generally classified into two categories, refined and
synthetic. Refined oils are produced from the refinement of existing
petroleum or vegetable oils and synthetic oils are produced from chemical
synthesis. Synthetic oils are much more expensive than refined oils, but
provide lower pour points, lower coefficients of friction, better oxidation
stability and a better viscosity index.
In this course, the student will learn the basics of
lubricating oils including how they are manufactured and the relative merits
between different types. The course will cover Chapter 3, "Lubricating
Oils" and Chapter 7, "Lubricant Additives" in
the US Army Corps of Engineers document EM 1110-2-1424, "Lubricants and Hydraulic
Fluids".
The student must take a multiple-choice quiz consisting of
ten questions at the end of
this course to obtain PDH credits.
