What are the 3 kinds of maintenance activities and its function?

The Three Types of MaintenanceCorrective Maintenance. Corrective maintenance is what to do when something breaks; it's better known as repairs. Preventive maintenance tries to spread costs by planning activities on a regular basis. 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 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. Unlike other styles, default maintenance is performed using rules and suggestions created by the original manufacturer, rather than the maintenance team. Technicians apply unplanned corrective maintenance to react as soon as a fault is detected that could not be anticipated with preventive maintenance processes.

Corrective maintenance can be planned or unplanned, depending on whether or not a maintenance plan has been created. But, in many people's minds, fault maintenance is urgent maintenance, maintenance that needs to be done right now. Predictive maintenance is generally considered to be the most advanced and intensive type of maintenance. Industrial maintenance processes and maintenance programs are the cornerstone of productivity and business reliability.

Therefore, emergency maintenance is the only type of maintenance that we really want to avoid as much as possible. Regardless of the decision you make, you need to provide maintenance teams with maintenance management software to ensure proper supervision of interventions, as well as smooth communication between technicians and other professionals. 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. Condition-based maintenance is sometimes considered a more advanced alternative to preventive maintenance.

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. For condition-based maintenance and predictive maintenance, for example, sensors mounted on your assets and equipment capture a constant stream of data that you can use to help determine when to schedule upcoming inspections and maintenance tasks. 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. .
