Oil mist lubrication is used on literaily thousands of pumps and electric motors in the U.S. petrochemical industry. This lubrication method has been demonstrated to reduce rolling element bearing failures by as much as 90%, generating significant technical and economic advantages over other lubrication systems. Here is the complete explanatory guide to this modern reliability and profitability improvement approach. The comprehensive text explains how extensive research at Texas A&M University in the late 1980's and early 1990's has solidified our understanding of the underlying reasons why and how oil mist actually works in the safest, most reliable, and cost-effective fashion.

As of 2013, the accuracy of this text has been reaffirmed. The bearings of over 100,000 process pumps and many thousands of electric motor drivers are lubricated with oil mist as of 2013. Surprisingly, the cross-section views, photos and narratives found in this remarkable book are still current and relevant today---some 47 years after a facility in Venezuela converted its pumps to oil mist lubrication and 38 years after 14 unit-wide oil mist lubrication systems were commissioned as the "initial going-in" lube application method at a large petrochemical plant in Texas. We recently decided to use this text in a Master Class on Oil Mist Lubrication and recommend it as the best available book on the subject.

Page 9 - ... statistics. However, some generalized approaches are available and are offered later in this text. OPERATING PRINCIPLES AND SYSTEMS OVERVIEW As stated in the introduction, oil mist is a centralized lubrication system in which the energy of compressed gas, usually thoroughly dry air taken from the plant instrument air supply, is used to atomize oil, which is then conveyed by the air in a low-pressure distribution system to multiple points of lubricant application. In the hydrocarbon processing...

Between-bearing pump bracket receiving continuous oil mist lubrication (courtesy of Lubrication Systems Company, Houston, Texas). because the system pressure is very low, oil mist is a reliable lubrication method. Proper lubrication system operation can be interlocked with pump operation or an alarm system, assuring adequate lubrication. The savings due to lower preventive maintenance labor requirements, equipment repair cost avoidance, and reductions in unscheduled production...
