Preventive Maintenance, 3rd Edition

This new enlarged and updated edition of a best-selling classic shows how the investment in a preventive maintenance program repays a company in longer equipment life, smoother operation, planning, and scheduling. It includes enhanced techniques and insights along with new chapters dealing with computerized PM systems. Preventive maintenance means all actions intended to keep durable equipment in good operating equipment and avoid failures. New technology has improved equipment quality, reliability and dependability by fault-tolerance, redundant components, self-adjustments, and replacement of hydraulic and mechanical components by more reliable electronic and optical operations. However, many components can still wear out, corrode, become punctured, vibrate excessively, become overheated by friction or dirt, or even be damaged by humans. Fortunately, modern sensors and computers for condition monitoring and on-condition need-detection enable many equipments to "call home" to report they need PM before they fail. The preventive maintenance advantage is that you will pay less now to do planned work when production is not pushing versus very expensive emergency repairs that may be required under disruptive conditions and cause production to halt and lose revenue. Good PM saves money over a product's life cycle. The book addresses major types of maintenance; advantages and disadvantages of PM; designing a PM program; economics of PM; nondestructive testing; scheduling; metrics; data issues; and much more.
