What is maintenance and its type?

Maintenance, in general, can be defined as the efforts made to maintain the condition and performance of a machine always the same as the condition and performance of the machine when it is still new. Preventive maintenance aims to detect and fix problems before they occur. It is usually carried out in the form of regular inspections, which usually occur several times a year. The main benefit of preventive maintenance is that it can eliminate unplanned downtime, since the ideal is to detect problems before they occur.

Condition-based maintenance is sometimes considered a more advanced alternative to preventive maintenance. Instead of being inspected according to a schedule, machines and systems are carefully observed for changes that may indicate imminent failure. Simplify preventive maintenance, schedule work orders, and track inventory Here, you use a schedule of inspections and tasks to find and fix small problems before they have a chance to become major problems. Preventive maintenance is basically the idea behind the old saying that “An ounce of prevention is worth more than a pound of cure.

One way to understand the benefits of preventive maintenance is to analyze all the problems that are avoided. Default maintenance is simply following the manufacturer's recommendations for maintenance, including when to perform inspections and maintenance. For assets that don't fit either of these descriptions, it probably makes more sense to use preventive maintenance. As with many other strategies, you don't have to make a difficult decision between strictly one or the other.

When an asset is newer, you can use default maintenance. Later, when you have created a maintenance and repair history, you can begin to adjust the schedule to best suit your specific situation. Choosing the right maintenance strategy starts with understanding your options, benefits, and drawbacks. Execution to failure tends to get a bad reputation, but for a specific asset class and equipment, it's the best option.

Use when things are difficult or impossible to maintain, cheap to carry in inventory, easy to replace, or not essential to your operations. Preventive maintenance helps you find problems ahead of time when scheduling inspections and tasks. It also saves you money and frustration because you can plan everything in advance. For default maintenance, everything is basically the same as with preventive maintenance, except that it follows a schedule set by the manufacturer, not by your department.

Condition-based and predictive by relying on sensors and special software to collect and analyze data from sensors installed directly on or near your assets. For conditions, the software looks for readings outside the preset parameters. For predictive purposes, the software analyzes the data to predict future failures long before they begin to develop. In the end, there is no one and only perfect strategy for all time.

You need to choose the combination that works best for your assets, adjust your focus as your assets age and your department collects data. This type of maintenance is performed by technicians in charge of industrial maintenance before any failure or malfunction occurs. Refers to spare parts, components and machinery and equipment to reduce the risk of failure. The digitalization of industrial enterprises has provided many IT and technology solutions that allow technicians to effectively perform, monitor, track and plan preventive maintenance.

The emergence of data processing and analysis solutions, as well as artificial intelligence, has allowed manufacturers to plan predictive maintenance based on the prediction of failures and malfunctions. This type of industrial maintenance allows companies to anticipate problems by planning necessary interventions and maintenance operations based on forecasts. In this way, you can limit expenses caused by unexpected breakdowns, equipment downtime and production interruptions. This type of preventive maintenance is distinguished by its frequency.

Technicians perform this regularly and systematically at well-defined time intervals beforehand. This allows components and spare parts to be replaced regularly, improving machine productivity. Therefore, systematic preventive maintenance is based on the regular inspection of the various equipment, which allows maintenance technicians to gather the necessary information about the various components of the production line and effectively prevent breakdowns and repair costs. Conditional preventive maintenance consists of monitoring the key parameters and indicators of the operation of the property and implementing the necessary corrective actions to anticipate any failure or malfunction.

There are many emerging IT tools available to automate this type of industrial maintenance. Thus, technicians and maintenance workers can simplify and facilitate their work by opting for the digitalization of industrial maintenance processes. If during the routine maintenance inspection of a car you discover signs of severe wear and tear, you should perform corrective maintenance. Until recently, when talking about predictive maintenance (PDM), this was essentially synonymous with condition-based maintenance.

This is because this type of maintenance does not go through the scheduling process of full maintenance planning %26 because it is very urgent and is simply planned on the fly. Technicians apply unplanned corrective maintenance to react as soon as a fault is detected that could not be anticipated with preventive maintenance processes. If you have resource constraints, you need to ensure that you have high productivity during execution (read my articles on maintenance planning, scheduling %26) and that you don't waste your scarce resources on preventive maintenance tasks that add no value (read my article on the principles of modernity maintenance). Property maintenance is best defined as any preventive or corrective maintenance action taken to keep a property fully functional and operating in its best condition.

Predictive maintenance refers to a specific type of condition-based maintenance in which systems are constantly observed through sensor devices. When choosing corrective maintenance as a strategy, it is essential to ensure that the failure modes considered do not have the potential to become emergency maintenance. Whereas preventive maintenance is maintenance that has been identified to prevent or mitigate a failure mode. Therefore, emergency maintenance is the only type of maintenance that we really want to avoid as much as possible.

When routine maintenance can be performed on a daily, weekly, or monthly basis, planned maintenance can be scheduled once a year or as needed. A next-generation CMMS such as Mobility Work, a solution that offers a performance analysis tool capable of collecting all the data entered by the maintenance teams themselves, aims to progressively help plants evolve towards predictive maintenance. Among all the types of maintenance mentioned above, condition-based maintenance is the most complicated to implement. Even if preventive maintenance doesn't always allow maintenance teams to anticipate each breakdown or failure, since it's still very difficult to know exactly which components are about to fail, it helps them reduce the extent of errors.
