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.

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. Example : An elevator undergoes regular inspections that include a diagnostic test to determine if parts should be replaced. It predicts when equipment failures might occur and to prevent the occurrence of the failure by performing maintenance.

Difference Between Preventive vs. Predictive Maintenance

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. Under a preventive management approach, the relevant parts will be removed, replaced, or rebuilt on or before the expected failure point. But preventive maintenance is not as simple as just always running maintenance on all your assets. Maintenance costs money, and you need to make strategic decisions about where and when to use it to keep your facility running optimally.

Reactive Vs. Preventive Vs. Predictive Maintenance

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. Reactive maintenance is appealing because it offers the maximum utilization and in turn maximum production output, of the asset by using it to its limits. The cost of repairing the asset after failure can potentially be more than the production value received by running it to failure.

Because they are somewhat similar, people tend to question the difference between the two. This helpful article helps define the difference between preventive and predictive maintenance and explains when your organization should be using one over the other. Preventive maintenance is a planned or scheduled maintenance, performed even when machines or the systems are in complete functional mode, to prevent any breakdowns or issues from occurring in the future.

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.

Preventive vs. Proactive Maintenance: What’s the Difference?

Preventive Maintenance : Preventive Maintenance, as name suggests, is a preventive action that is used to prevent any unexpected failure from occurring in future. Its main aim is to identify problems that are small at initial and can lead to major issue. After then, resolve it before major problem develops.

What Is the Difference Between Predictive and Preventive Maintenance?

 Сьюзан, - сказал он, волоча ее к лестнице, - уходи со. Клянусь, что я тебя пальцем не трону. Сьюзан пыталась вырваться из его рук, и он понял, что его ждут новые проблемы.

Мысли ее по-прежнему возвращались к сотруднику лаборатории систем безопасности, распластавшемуся на генераторах. Она снова прошлась по кнопкам. Они не реагировали.

У нее есть и свои слабости. Она ведь и сама кое-что себе позволяла: время от времени они массировали друг другу спину. Мысли его вернулись к Кармен. Перед глазами возникло ее гибкое тело, темные загорелые бедра, приемник, который она включала на всю громкость, слушая томную карибскую музыку.

 Отпусти ее, - раздался ровный, холодный голос Стратмора. - Коммандер! - из последних сил позвала Сьюзан. Хейл развернул Сьюзан в ту сторону, откуда слышался голос Стратмора. - Выстрелишь - попадешь в свою драгоценную Сьюзан.

Он забыл нажать кнопку, которая отключила звук. Этот прибор он купил в магазине электроники, оплатив покупку наличными, чтобы сохранить анонимность.

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.

The theory behind preventive maintenance is to take regular steps to prevent problems before they occur.
