Machinery Problem-Solving Sequence Course
Introduction:
Course Objectives:
The course presents a systematic approach to fault diagnosis and failure prevention. It firstly adopts a general approach to machine deterioration, the mechanisms involved and the ways in which common deteriorative modes can be combated. It then turns to component-oriented studies of failure mechanisms in common items of plant. For each component type or machine system, the on-line and off-line symptoms of deterioration are presented, with significant emphasis being placed upon an inspection-based approach. Statistical methods of failure analysis are presented and examples are used to demonstrate best practice in the collection, analysis and interpretation of such data. Finally, the course dwells upon the use of condition monitoring methods in a failure analysis and prevention role, and in particular upon the use of machinery vibration monitoring and analysis.
