Download or read book Effect of Engine Operating Environments on Lubricant Load Carrying Capacity of High Gear Load Oils written by P. J. Mangione and published by . This book was released on 1979 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Load carrying capacity evaluations were made on current and advanced esterbased synthetic lubricants which were exposed to the operating environments of gas turbine engines. The program also investigated the cause/effect of changes in load carrying capacity as related to additive depletion and possible additive/metal interaction through an adsorption or reactive process. The results indicated that both current oils and advanced high gear load oils experienced significant degradation in load carrying capacity with time in both engine and simulated engine bearing compartment environments. The percentage loss in load carrying capacity was greater with the high gear load oils, but neither oil was significantly influenced by the engine type sampled. However, the absolute rating of the degraded XAS-2354 oil remained above the degraded MIL-L-23699 oil absolute ratings. The lower load carrying capacity of used oils, attributed to additive depletion, appeared to be recoverable with new oil additions of a high gear load oil. However, this capability would not be realized in normal operation of an engine lubrication system. An effective pre-conditioning treatment of gear tooth surfaces with a high gear load oil was demonstrated and recommended for use in the 'run-in' of new or overhauled helicopter gearboxes for improved resistance to surface damage and extended service life.

Download or read book Refining Used Lubricating Oils written by James Speight and published by CRC Press. This book was released on 2014-04-07 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Used lubricating oil is a valuable resource. However, it must be re-refined mainly due to the accumulation of physical and chemical contaminants in the oil during service. Refining Used Lubricating Oils describes the properties of used lubricating oils and presents ways these materials can be re-refined and converted into useful lubricants as well as other products. It provides an up-to-date review of most of the processes for used lubricating oil refining that have been proposed or implemented in different parts of the world, and addresses feasibility and criteria for selecting a particular process. The book begins with an overview of lubricating oil manufacturing, both petroleum-based and synthetic-based. It reviews the types and properties of lubricating oils and discusses the characteristics and potential of used lubricating oils. The authors describe the basic steps of used oil treatment including dehydration, distillation or solvent extraction, and finishing. They explore the combustion of used oil for use as fuel, covering chemistry and equipment, fuel oil properties, and combustion emissions. The book considers alternative processing options such as refinery processing and re-refining. It also reviews the major refining processes that have been suggested over the years for used oil. These include acid/clay, simple distillation, combinations of distillation and hydrogenation, solvent extraction, filtration, and coking processes. The book addresses economic, life cycle assessment, and other criteria for evaluating the attractiveness of an oil recycling project, examining various costs and presenting an economic evaluation method using an Excel spreadsheet that can be downloaded from the publisher’s website. The book concludes with a chapter offering insights on how to choose the most suitable process technology.

Download or read book Engineering Tribology written by G.W. Stachowiak and published by Butterworth-Heinemann. This book was released on 1993-06-30 with total page 901 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interdisciplinary nature of tribology encompasses knowledge drawn from disciplines such as mechanical engineering, materials science, chemistry and physics. The interaction between these different fields of knowledge to achieve the final result, the control of friction and wear, is reviewed in this volume. This interdisciplinary approach has proven to be a very successful way of analysing friction and wear problems. In many cases tribology is viewed as an inaccessible subject which does not produce useful answers. In this volume the authors redress this problem by providing a comprehensive treatment of the subject. A basic feature of the book is the emphasis on describing various concepts in an accessible manner for the benefit of non-specialists. This principle is applied from the beginning of the book, where the reader is introduced to the fundamental concept of tribology. This concept is then often used to show how the various topics in tribology are interrelated to form one coherent subject. A direct graphical illustration of the mechanisms controlling tribological phenomena is presented. Carefully prepared diagrams allow rapid appreciation of the basic ideas and facts in tribology. The numerical analysis of hydrodynamic lubrication is supported by a number of computer programs which are included in the book. The control of wear is given extensive treatment with a thorough discussion of lubricant additives, solid lubricants and surface coatings. The effectiveness of coatings in suppressing specific forms of wear is analyzed together with the methods of coatings deposition. The book contains 474 figures and 44 tables. More than 1000 references are provided to give the reader access to more specialized information if required. The volume is intended to provide graduates in engineering or materials science with an understanding of the fundamental concepts of friction, wear and lubrication.

Book excerpt: The constitution, properties, production and applications of lubricants and related fluids of all states of aggregation are reviewed in this volume. Special attention is devoted to synthetic lubricants and to additives for lubricants. Standards of quality are listed, together with systems of classification and the most important specifications and methods of testing the properties of lubricants and their performance in service. Future trends in lubricants are also discussed. Non-conventional lubricants and additives are examined in detail. The relationship between constitution and properties of lubricants, e.g., the viscosity -temperature -pressure relationship, the behaviour in ageing, the biodegradability, synergisms and antagonisms in the blends of lubricants, of additives and lubricant-additive are analyzed. Guidelines for the selection of lubricants and fluids in the design, service and maintenance of machines and machine parts are also given. The work will be of interest to all those involved in the research and development of petrochemical and machinery industries, as well as lecturers and students specializing in this field.
