Maintenance
techniques have come a long way.
The first maintenance
technique ever implemented was the REACTIVE MODE (If it ain’t broke,
don’t fix it). Machinery would run until it failed and the
maintenance department would scramble to repair it.
Things had to change. The
competitive market place would not allow for uncontrolled losses
with money being spent on unplanned down-time and catastrophic
failures, which are normal for this type of maintenance strategy.
The next step in the
evolution of maintenance was the time based PREVENTATIVE MODE.
Bearings were greased, belts were changed, and machines were
rebuilt, according to wear and tear and the age of the machine.
This helped cut costs and
the amount of failure was reduced. However, machines would still
fail with no warning, causing the unplanned down-time and no one
knew if the machines and parts being repaired or replaced really
needed to be repaired or replaced. This can cut deep into the
pockets of any company.
As technology advanced and
the need for machine reliability increased, the PREDICTIVE and
PROACTIVE MODES were developed. It is now possible to collect and
analyze machinery information on a periodic interval. Using this
technique we can analyze such things as Vibration, Ultrasonic, Oil
and Temperature signatures and predict when maintenance should be
performed (Predictive Maintenance). Using these same technologies,
we can also determine why maintenance is needed and correct the root
cause of the problem (Proactive Maintenance). This allows a company
to plan down-time and repair machinery on a regular maintenance
schedule. The machinery and parts that need to be repaired or
replaced are, and the ones that don’t need to be repaired or
replaced aren’t.
The
evolution of maintenance strategies from the REACTIVE MODE to
today’s PREDICTIVE and PROACTIVE MODES means that your company can
now more accurately budget both time and money for machine
maintenance, a savings that will benefit your efficiency as well as
your bottom line. |
