R Beebe

6 points · 78 hours · Full-year subject · Gippsland/distance · Prerequisite: GEG7024

Objectives The student is expected to acquire understanding of maintenance philosophies, the application of condition monitoring of rotating and stationary machinery, including effects of hostile environments and approaches to fault diagnosis. The student will also recognise the importance of predictive maintenance and be able to set up and run a condition monitoring program.

Synopsis Maintenance strategies. Basic Weibull analysis to find which stage of the machine life cycle is occurring. Benefits of CM. Visual inspection techniques. Non-destructive testing. Analysis techniques for wear debris/contaminants in lubricants. Fault diagnosis from gaseous products in insulating oils. CM of electrical machine. Measurement of pressure, temperature, flow and other variables. Performance analysis applied to common machine types. Overall vibration level and severity. Frequency analysis. Vibration phase angle. Monitoring rolling element bearings. Balancing methods. How to justify investment in condition monitoring. Applying condition monitoring. Systematic ways of diagnosing faults in physical assets. Effects on plant life of hostile environments, such as temperature and corrosive surroundings and how the effects are detected, monitored and controlled.
