Predictive, preventive, and breakdown maintenance tips
Predictive, preventive, and breakdown maintenance are common maintenance programs that provide their own unique benefits and plant managers should know when to employ them.
An established maintenance program helps save money, energy and time. That said, there are many different maintenance program options to choose. The most common are preventive, predictive, and breakdown. What is the difference between these maintenance programs?
There is often enough data to establish a predictive maintenance (PdM) program. PdM is not a type of program that determines if something has gone wrong. Rather, it prevents something from going wrong. A PdM program looks at the expected, or average, the life of the equipment and related statistics. The program determines when a problem is most likely to occur, either with the equipment or with a component within the equipment. In this way, the maintenance takes place before the problem occurs. One of the primary benefits of a predictive maintenance program is it limits downtime. It may be necessary to take the equipment offline to perform the maintenance. But since it is being done ahead of a failure, it allows the user to pick and choose the times when the maintenance occurs.
A preventive maintenance program looks for triggers that identify when a problem is likely to occur. It relies on testing, both online and offline, of any equipment that falls under the program. Preventive maintenance discovers any issues before a catastrophic failure. Preventive maintenance involves routine equipment testing and maintenance when identifying a problem. Applying an effective preventative maintenance program saves money by replacing or rebuilding a failing part.
Breakdown maintenance is perhaps the least desirable of the three different types of maintenance programs. This type of maintenance involves repairing or rebuilding the equipment, just as the other maintenance programs. The trigger event, though, is the actual breakdown of the equipment. Breakdown maintenance can be beneficial if it's used with preventive and predictive maintenance. It may still be necessary, at times, to use breakdown maintenance as a program when unexpected events take place. If it is the only type of maintenance in place, yet, it tends to be the most costly option.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
