This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts were made to develop a performance test for Viton O-rings to be used in 3000 psi hydraulic service. The service fluid may be either petroleum base or Cellulube 220. The test apparatus consisted of a piston with two O-rings which reciprocates 100 times/min in a vertical cylinder o 2.63-in. internal diameter. The piston travel is 1-1/2 in. The cylinder is held at 160 F. Teflon back-up rings are used on the downstream side of the O-rings. The pressure-on cycle lasts for 9 min; the pressure-off cycle lasts for 1 min. Leakage at both ends of the piston is collected. Difficulty was experienced in obtaining reproducible results with this equipment when the criterion was time required for a definite leakage (20 cc) to occur at 3000 psi fluid pressure. The test results show that Viton O-rings seal Cellulube 220 satisfactorily under these conditions and are not damaged by this treatment. The investigation is being continued wit the criterion changed t the number of cycles before the leakage in a 24-hr period exceeds 15 cc for either O-ring. (Author).

This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of dynamic performance tests of Viton B O-rings indicate that Viton B O-rings of 70 Shore A hardness with Teflon backup rings will perform satisfactorily at 180 F in 3000 psi hydraulic systems containing phosphate ester fluids. In addition, the results indicate that the O-rings will perform equally as well under these conditions in hydraulic systems containing petroleum base fluids. As reported previously, the Teflon backup rings do not stand up at 300 F under the test conditions. Backup rings made of a 90 Shore A Viton B stock showed even greater wear. (Author).

Book excerpt: Seals and Sealing Handbook, Sixth Edition provides comprehensive coverage of sealing technology, bringing together information on all aspects of this area to enable you to make the right sealing choice. This includes detailed coverage on the seals applicable to static, rotary and reciprocating applications, the best materials to use in your sealing systems, and the legislature and regulations that may impact your sealing choices.Updated in line with current trends this updated reference provides the theory necessary for you to select the most appropriate seals for the job and with its 'Failure Guide', the factors to consider should anything go wrong. Building on the practical, stepped approach of its predecessor, Seals and Sealing Handbook, 6th Edition remains an essential reference for any engineer or designer who uses seals in their work. - A comprehensive reference covering a broad range of seal types for all situations, to ensure that you are able to select the most appropriate seal for any given task - Includes supporting case studies and a unique 'Failure Guide' to help you troubleshoot if things go wrong - New edition includes the most up-to-date information on sealing technology, making it an essential reference for anyone who uses seals in their work

Download or read book Exploring Geoethics written by Martin Bohle and published by Springer. This book was released on 2019-03-13 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the potential of geoethics, as designed within the operational criteria of addressing the deeds and values of the human agent as part of the Earth system. It addresses three key questions: i) what should be considered 'geoethics' in an operational sense, ii) what is peripheral to it, and iii) is there a case therefore to establish a denomination, such as geo-humanities or geosophy, to capture a broader scope of thinking about geoscience and its interactions with society and the natural world, for the benefit of the geo-professionals and others. The book begins by framing, contextualising and describing contemporary geoethics, then goes on to cover several examples of geoethical thinking and explores the societal intersections of geosciences in the planetary ‘human niche’. The concluding chapter discusses the challenges facing the emerging field of geoethics and how it may evolve in the future. Bringing together a set of experts across multiple interdisciplinary fields this collection will appeal to scholars, researchers, practitioners and students within geosciences and social sciences, political sciences as well as the humanities. It will interest those who are curious about how ethical reflections relate to professional duties, scholarly interests, activities in professional geoscience associations, or responsible citizenship in times of anthropogenic global change.
