Abstract:

A predictive maintenance program was developed for a treatment plant with a large number of pieces of critical mechanical equipment. Using an inexpensive, portable vibration meter, data was accumulated to monitor the changing mechanical condition of critical pieces of equipment. Using a computer and database software, an information handling system for the predictive maintenance program was developed. Each piece of critical mechanical equipment in the predictive maintenance program had a dedicated file. Each file had a record containing the date of the vibration reading and the actual vibration readings. From the stored data, statistical and graphical capabilities of the software were used to analyze and graph the data to provide the facts for planning maintenance based on prediction. Utilizing this system, a decision could be made as to when equipment was to be repaired before a critical failure occurred.
