![]() ![]() On the other hand, you may want to inspect a piece of equipment that halts production if it fails weekly to ensure everything is operating correctly.ĭepending on the task, and your preference, you can choose to schedule recurring tasks based on the day of the week/month (e.g., the 1st of every month) or the last executed date (e.g., 3 months from the previous time the task was completed). Depending on the PM task, you may need to set up maintenance work and inspections to occur daily, weekly, monthly, semi-annually, annually, or any other time-based maintenance interval.įor instance, manufacturers recommend semi-annual inspections and maintenance on HVAC units-once before the summer and once before the winter. This type of preventive maintenance is performed at set intervals of time and is most beneficial for equipment that needs to be serviced based on a calendar schedule. Consider the analogy of car maintenance, and the example of the car that doesn’t receive regularly mandated service, only to suffer a catastrophic, multi-system failure that suddenly demands extensive and expensive repairs.Īlthough adopting preventive maintenance measures requires budgeting in regular service activities and may necessitate the adoption of a computerized maintenance management system (CMMS), in an industrial setting it’s usually worth it, especially since when an industrial operation is down for unscheduled repairs, it can quickly cause stalled production or even lost revenues.While there are several types of maintenance management, preventive maintenance can be broken down into two basic categories: time-based and meter-based. The method selected - preventive maintenance or reactive maintenance - wouldn’t matter nearly as much except for the fact that reactive maintenance can easily become far costlier than preventive maintenance. On the other hand, preventive maintenance tries to anticipate equipment failure and take corrective action before mechanical breakdown occurs. Then the needed repair must be accomplished as soon as possible. Reactive maintenance adopts a “run-to-fail” policy whereby maintenance doesn’t occur at all until a piece of equipment actually stops working. One main aspect separates preventive maintenance from reactive maintenance: timing. Explore a predictive maintenance solution With machines generating constant updates about their activities and condition, predictive maintenance models are now getting the abundance of data they need to produce crucially needed maintenance predictions. ![]() Predictive maintenance flourishes in conjunction with IoT. Once armed with that extra data, predictive maintenance models can churn powerful predictions that let operators know with certainty when system failures will occur.Īnd because repairs scheduled through predictive maintenance occur exactly before they’re needed (and not according to a general timetable), no unnecessary repairs are made - which keeps maintenance budgets leaner. Information about the expected lifecycle of that equipment model is combined with historical data about the performance of that particular unit. Predictive maintenance, on the other hand, is considerably more precise, and because of this, requires substantially more data. We would know approximately when maintenance should occur. If we were practicing preventive maintenance on that equipment, we might use general information about that make and model of machine to formulate rough time estimates about when regular maintenance should be carried out on it. ![]() But predictive maintenance takes the concept even further.Ĭonsider a single piece of industrial equipment. Both types try to proactively anticipate and prevent mechanical failures. In reality, predictive maintenance is a more evolved form of preventive maintenance. Unfortunately, this attempt to frame the relationship in simple terms of preventive maintenance vs predictive maintenance misses a key point. ![]() There’s often an impulse to regard preventive maintenance and predictive maintenance as completely distinct entities. ![]()
