What are the two main types of maintenance?

Preventive maintenance aims to detect and fix problems before they occur. It is usually carried out in the form of periodic inspections, which are usually carried out 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.

Rather than inspecting them on a schedule, machines and systems are carefully observed for changes that could indicate an imminent failure. Another is that new technologies enable new strategies. When new technology gives us new capacity, we can take advantage of it in a new strategy. For condition-based maintenance and predictive maintenance, for example, the sensors installed 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.

Here, you use a program of inspections and tasks to find and fix small problems before they have a chance to turn into big 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 consists of simply following the manufacturer's recommendations for maintenance, including when to perform inspections and maintenance.

Basically, it's the same as condition-based maintenance, except that the data is analyzed to make accurate predictions about future faults. It now has the same maintenance costs depending on the conditions, plus the additional cost of even more sophisticated software that requires even more specialized training for its staff. For assets that don't fit any 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 choice between strictly one or the other.

When an asset is newer, you can use default maintenance. Later, when you've created a maintenance and repair history, you can start adjusting the schedule to better suit your specific situation. Choosing the right maintenance strategy starts with understanding your options, benefits and drawbacks. The tendency to fail usually has a bad reputation, but for a specific asset class and equipment, it is the best option.

Use it 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 detect problems early by scheduling inspections and tasks. It also saves you money and frustration, since you can plan everything in advance. For default maintenance, everything is basically the same as with preventive maintenance, except that you follow a schedule set by the manufacturer, not by your department.

State-based and predictive using sensors and special software to collect and analyze data from sensors installed directly on or near your assets. Depending on the conditions, the software searches for readings outside the preset parameters. For prediction, the software analyzes the data to predict future failures long before they begin to develop. In the end, there is no perfect strategy for all time.

You must choose the combination that best suits your assets, adjusting your approach as your assets age and your department collects data. While planned maintenance and scheduled maintenance seem the same, there are some essential differences between them. In a nutshell, planned maintenance details how and what work will be completed; scheduled maintenance determines who will complete the work and when it will be completed. Preventive maintenance is great because it helps an organization to anticipate problems before they occur.

Preventive maintenance can also help reduce downtime, especially for the unplanned variety, as the organization can prepare for maintenance. On the downside, preventive maintenance still doesn't guarantee that a machine or part won't fail. However, it helps to mitigate unexpected failures. Also on the downside, since preventive maintenance is based on performing maintenance before a failure occurs, organizations could be replacing parts or performing maintenance that isn't really necessary.

There are several preventive maintenance models for organizations to consider and determine which one is right for them. Preventive maintenance focuses on ways to stop a fault before it occurs. Corrective maintenance, on the other hand, is performed when a problem is detected or the machine fails. Because of this, corrective maintenance can result in prolonged downtime, as organizations struggle to find replacement parts or fix the problem.

On the other hand, organizations won't replace the good parts, only the bad. Obviously, preventive maintenance is the key to mitigating downtime and increasing efficiency. The most appropriate type of preventive maintenance depends on your organization and on which one works best for it, its processes, its machines and its equipment. Unlike other styles, default maintenance is carried out using rules and suggestions created by the original manufacturer, rather than the maintenance team.

Preventive maintenance systems can be expensive because of their large programming needs, while reliability-focused maintenance systems tend to have a higher initial cost. However, the problem is that most people think of traditional time-based maintenance when they talk about preventive maintenance. Predictive maintenance refers to a specific type of condition-based maintenance in which systems are constantly observed through sensor devices. All preventive maintenance must be planned maintenance, since it has been identified in advance and there is no reason why it should not undergo the normal scheduling process of maintenance planning %26.My point for further discussion: What about maintenance design as a way to improve capacity or reduce maintenance and other one-off maintenance opportunities?.

Unfortunately, books rarely specify this distinction, leading to the mixing of oranges and apples under the same general term of “maintenance tasks”, which is not precise enough to correctly describe other maintenance concepts within preventive maintenance. The most expensive type of maintenance is emergency maintenance, since it is the type of maintenance that is so urgent that everything is left to work and solve the problem. Time-based maintenance is basically a type of maintenance that is performed at regular intervals while the equipment is still operating with the goal of preventing failures or reducing the likelihood of failure. Corrective maintenance may or may not be planned, depending on whether or not a maintenance plan has been created.

An efficient and effective preventive maintenance program will have a combination of all these different types of maintenance. There are different types of maintenance because maintenance teams from different organizations have different budgets, equipment needs, and service-level agreements with customers and internal departments, such as production. While preventive maintenance is maintenance that has been identified to prevent or mitigate a failure mode. Maintenance planning is the process of determining what maintenance work should be done and how it should be carried out.

You can avoid that problem with ongoing property maintenance training offered by the Interplay Learning online course catalogs. Once the CMMS has analyzed all the information, maintenance teams can view all interventions, see how often a maintenance operation has been carried out, and anticipate unplanned downtime to react accordingly. . .
