File Name: difference between preventive and predictive maintenance .zip
Last Updated: January 6, Greg Arbour 1 min read. The idea behind preventive maintenance PM is that by performing regular maintenance on equipment, you reduce the chances of that equipment failing. Preventive maintenance also called planned maintenance or planned preventive maintenance is driven by time, meter or event-based triggers.
The theory behind preventive maintenance is to take regular steps to prevent problems before they occur. Preventive maintenance has several characteristics:. Essentially, preventive maintenance is a collection of best practices and averages that zeroes in on an identified interval that gives you the best odds of catching issues before they start. It continues to be practiced because it is highly effective for many organizations. Like preventive maintenance, it is a proactive approach. While preventive maintenance relies on best practices and historical data, predictive maintenance takes measurements from machine operations as they are occurring and uses this data to raise red flags when indications of a problem are noted.
Both are effective strategies for asset maintenance , but you need to understand the differences between the two and how they work together. In a preventive maintenance strategy, facilities managers perform systematic inspections of assets and execute routine maintenance to prevent unexpected equipment downtime or failure. Unlike reactive or corrective maintenance where service occurs after the asset has malfunctioned, preventive maintenance requires performing maintenance before anything malfunctions. Different types of preventive maintenance involve the use of different triggers to determine when to service the equipment. Here are a few examples of preventive maintenance:. Preventive maintenance is appropriate for assets that are mission-critical for day-to-day operations and are more likely to fail as they age.
Across industry, many definitions are used when it comes to the different types of maintenance. As far as I am concerned terminology is not important. Other than making sure we are talking about the same thing. As long as we can sensibly talk about the underlying principles. At least, the way I see it:. Corrective maintenance is done after a failure has occurred either as Deferred Corrective Maintenance or as Emergency Maintenance. In the rest of this article, I will discuss each of these different types of maintenance I detail:.
It is not uncommon for people to use the terms Preventive Maintenance and Predictive Maintenance interchangeably. Although they are similar in that they describe maintenance measures that are designed to address failures or operating problems from occurring, the ways with which these steps are planned and then executed are very different. Read on to find out what the differences are. Preventive maintenance measures are planned and performed on equipment with the purpose of ensuring that failures do not occur and to mitigate the consequences of breakdowns. These are routine measures that are completed regardless of the current operating condition, i. These measures are usually determined by time e.
It can be difficult to determine how often a machine should be taken offline to be serviced as well as weigh the risks of lost production time against those of a potential breakdown. Currently, most maintenance organizations are forced to handle this dilemma with a complicated balancing act between maximizing the useful life of a part and asset at the risk of machine downtime. Thankfully, the rise of new connected technologies can enable machines to maximize the useful life of machine components while also avoiding machine failure. Maintenance strategies traditionally fall into one of three categories, each with its own challenges and benefits:. Reactive maintenance describes the strategy of repairing parts or equipment only after the asset has broken down or been run to the point of failure.

For a maintenance manager or supervisor, it is necessary to know the different types of maintenance. Preventive maintenance measures are planned and performed on equipment with the purpose of ensuring that failures do not occur and to lessen the consequences of breakdowns. A preventive maintenance plan is ideal when a maintenance manager can prevent any malfunction of their equipment or can predict and plan for this failure so it has the least possible impact.

The key differences between preventive vs. predictive maintenance are: Preventive maintenance occurs on the same schedule every cycle — whether or not the upkeep is actually needed. With predictive maintenance, repairs happen during machine operation and address an actual problem.SimeГіn M. 27.12.2020 at 10:06
Predictive maintenance (otherwise known as condition-based maintenance) differs from preventive maintenance in the sense that it requires predetermined and.
