As far as I am concerned, jargon is not really that important. As far as we both know that we are talking about the same thing. What I think as condition-based maintenance, you would know that predictive maintenance is not really that vital. As long as we are about to discuss about the underlying principles.
What is condition based maintenance and when can you apply it? In this article, we would learn about the various kinds of maintenance since there are a lot of people who are asking about it.
Corrective maintenance versus preventive maintenance
At the very outset, we see maintenance as either preventive or corrective. If you do preventive maintenance, it means that you are performing a task before failure would occur. And this task is aimed in preventing a mistake, decreasing the consequences of failure or evaluating the risks a failure would take place. But then again, when we say corrective maintenance, it means that the failure has already happened and we are just trying to reestablish the functionality of the equipment. To make things clear, corrective maintenance can be the result of a careful run to failure method.
What is preventive maintenance?
Preventive maintenance can be technically defined as “an equipment maintenance method that is contingent on restoring or replacing a valuable or asset at a preset interval regardless of its current status. Planned restoration tasks as well as replacement tasks are under your preventive maintenance tasks.
Preventive maintenance is also called as preventative maintenance, and this is basically a form of maintenance that is performed at regular intervals while the equipment is still at its best with the aim to prevent mistakes or decrease the chances that failure would take place.
And this type of maintenance is actually time-based, for instance, every week, every month, or every five months. On the other hand, preventive maintenance can also be constructed on the usage, for example, every 50 cycles, every 10000 hours, or similar to your car, service every 1000km.
In addition to time based maintenance or regular interval method, there are also other types of maintenance that is within the category of preventive maintenance and these are the following:
TBM or time based maintenance, FFM or failure finding maintenance, RBM or risk based maintenance, CBM or condition based maintenance and PDM or predictive maintenance.
The preventive maintenance includes a lot of different types of maintenance that are used before a failure would take place and predictive maintenance is also included in your preventive maintenance. When people would discuss about preventive maintenance, they mean time based maintenance which is replacing or repairing a fixed interval regardless of the current status of the equipment.
