Preventative maintenance is a schedule of planned maintenance actions aimed at the prevention of breakdowns and failures. The primary goal of preventative maintenance is to prevent the failure of equipment before it actually occurs. It is designed to preserve and enhance equipment reliability by replacing worn components before they actually fail. Preventative maintenance activities include;
- Equipment checks
- Oil changes at specified periods
- Minor repairs and adjustments
In addition, our technicians can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal preventative maintenance program would prevent all equipment failure before it occurs.
Value of Preventative Maintenance
There are multiple misconceptions about preventative maintenance. One such misconception is that a PM is unduly costly. This logic dictates that it would cost more for regularly scheduled downtime and maintenance than it would normally cost to operate equipment until repair is absolutely necessary. This may be true for some components; however, one should compare not only the costs but the long-term benefits and savings associated with preventative maintenance. Without preventative maintenance your run the risk of unscheduled equipment breakdown. Also, preventative maintenance will result in savings due to an increase of effective system service life.
Long-term benefits of preventative maintenance include:
- Improved system reliability
- Decreased cost of replacement
- Decreased system downtime
Long-term effects and cost comparisons usually favour preventative maintenance over performing maintenance actions only when the system fails.
