Preventive Maintenance
occurs when a machine, or parts of a machine,
are overhauled on a regular basis regardless of the condition of the
parts. While better than run to failure, preventive maintenance results in
excessive downtime due to unnecessary overhauls and the excessive costs
of replacing good parts along with worn parts.
Predictive Maintenance
is the process of determining the condition of
machinery as it operates, to predict and schedule the most efficient repair
of problem components prior to failure. Predictive Maintenance not only
helps plant personnel eliminate unplanned downtime and the possibility
of catastrophic failure, but allows them to effectively order parts, schedule
manpower, and plan multiple repairs during scheduled downtime.
5.1 Benefits of Predictive Maintenance
Documented experience proves that plants which establish a predictive
maintenance program are able to:
•
Improve Machinery Reliability
— reduced “unplanned failures”
•
Reduce Maintenance Costs
— knowing the exact problem to fix
•
Increase Production
— optimize machinery capabilities
•
Lower Energy Consumption
— less vibration usually means less
friction
•
Extend Bearing Service Life
— reduce vibration and lubrication
failures
•
Improve Product Quality
— where less vibration improves finish
The benefits are numerous and will vary depending upon the
implementation of your Predictive Maintenance Program.
