Description
Focusing on predictive maintenance, this book is a convenient guide to best practices for maintaining machinery and systems assets. It is a handy collection of graphs, charts, calculations, tables, curves, and basic rules of thumb that any engineer working with equipment will need. The authors share a wealth of professional experience in pointing out the most important factors that affect successful maintenance programs and the keys to ensuring that manufacturing systems perform reliably over time.
The book explains how to create and nurture a work culture that values predictive maintenance over reactive maintenance. It describes common technologies for performing predictive maintenance analyses, including vibration analysis, thermography, ultrasonics, and tribology analysis, and explains how to perform reliability analyses such as failure modes and effects analysis and root cause failure analysis. Common maintenance programs for mechanical and electrical components, including bearings, chain drives, belt drives, hydraulics, gears, compressors, packing seals, pumps, electric motors, and motor controls, are given. Also included are useful forms, checklists, and tips for checking maintenance schedules, inspections and tests.
