Predictive Maintenance

- What is it?
Regularly scheduled machine condition monitoring aimed at early detection and correction of machinery defects prior to failure.

- Why Predictive Maintenance?
Predictive Maintenance is the most cost effective method of maintaining critical machinery.  By identifying machinery defects early, costly and potentially catastrophic failures can be avoided.  Whereas Preventive Maintenance can also by utilized to minimize the risks of machinery down-time, with Predictive Maintenance, corrective action is recommended only when necessary.  Predictive Maintenance combines the old adages: "An ounce of prevention is worth a pound of cure" and  "If it ain't broke, don't fix it".

- How is it done?
Vibration Analysis is the primary tool in predicting machinery problems before they lead to failures.  Trend Analysis compares the latest parameters to historical and baseline data that was established with the equipment in good running order.  Frequency Analysis defines and looks for known fault frequencies such as bearing fundamental frequencies and motor rotor bar pass frequencies.  Phase Analysis compares how one part of a machine is vibrating in relation to another.  Temperature trending, and of course, the observations of an experienced and knowledgeable Technician are also used.
