What are the 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. This type of maintenance is carried out by the technicians in charge of industrial maintenance before any failure or malfunction occurs. Refers to spare parts, components and machinery and equipment in order to reduce the risk of breakdowns. The digitalization of industrial companies has provided many IT and technological 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 faults and faults. This type of industrial maintenance allows companies to anticipate problems by planning the necessary maintenance interventions and operations based on predictions. Therefore, it makes it possible to limit expenses caused by unexpected breakdowns, equipment downtime and production interruptions. This type of preventive maintenance is distinguished by its frequency.

Technicians carry it out regularly and systematically, with time intervals well defined beforehand. This allows components and spare parts to be replaced regularly, improving machine productivity. Therefore, systematic preventive maintenance is based on a periodic inspection of the various equipment, which allows maintenance technicians to gather the necessary information about the different components of the production line and effectively prevent breakdowns and repair costs. Conditional preventive maintenance consists of monitoring the parameters and key indicators of the operation of the property and implementing the corrective actions necessary to anticipate any faults or malfunctions.

There are many emerging IT tools available to automate this type of industrial maintenance. In this way, technicians and maintenance workers can simplify and facilitate their work by opting for the digitalization of industrial maintenance processes. It is well known that billions of dollars are lost every year due to unscheduled downtime and poor asset quality. In an endless battle to combat this statistic, organizations implement one of a variety of types of maintenance and often combine two or more.

The definitions of maintenance types vary from industry to industry, which can make it quite confusing to differentiate between aspects such as preventive and predictive maintenance, among others. Let's examine the most common types of maintenance used in the manufacturing and processing industries. For detailed information on types of preventive maintenance, how to design a preventive maintenance program, preventive maintenance tools, and more, see the link at the beginning of this section. While many organizations employ both predictive and preventive maintenance (76 percent use preventive and 65 percent use predictive, according to a recent survey by Reliable Plant), there are some key differences.

In particular, preventive maintenance does not require the condition monitoring aspect that predictive maintenance requires. This means that predictive maintenance uses condition-based technologies, such as infrared thermography, acoustic monitoring, vibration analysis and analysis. Another key difference is that preventive maintenance involves inspecting and maintaining assets regardless of whether the equipment needs maintenance (the maintenance program is based on a trigger). When it comes to types, techniques and costs of maintenance, the main types of maintenance can be compared with those of the human body to get an overview of the equivalent body maintenance task.

The following table uses an example of an energy generating asset and compares it to the human heart. Maintenance activators can be configured and used with various types of maintenance. Fault triggers are used with reactive maintenance or execution plans a. Predictive maintenance uses elements such as time-based triggers in the form of alerts to try to prevent a failure from occurring.

Other triggers that will be discussed include triggers based on events, usage, and conditions. Just as your car has its oil changed every 5,000 miles, any machine that performs operations with time or quantity restrictions can be configured with a usage-based trigger. The meter readings can be added to a CMMS and are used to set up alerts when the desired quantity or value is reached. Usage-based activators are a great way to keep equipment subject to irregular schedules and are most commonly used with predictive or preventive maintenance programs.

Technological advances prevail above all in condition-based monitoring, in the form of proactive and predictive maintenance. In this type of maintenance, technologies such as oil analysis, vibration analysis, thermography and motor current analysis can help determine the root causes and symptoms of faults, seek benefits such as extending machine life and early detection of faults, and reducing the Number and impact. The current technological revolution in the manufacturing industry has made it possible to reduce errors and defects, optimize production and reduce labor costs. Automated sensors that can continuously monitor machinery are among the biggest improvements.

Not only can they be used in various types of maintenance, but they can also generate an enormous amount of data that can be analyzed and used to improve processes. Regardless of the decision you make, you must provide maintenance teams with maintenance management software to ensure proper supervision of interventions, as well as smooth communication between technicians and other professionals. To clarify, corrective maintenance can be deliberate in the form of a maintenance strategy from execution to failure, which will be discussed below. Among all the types of maintenance mentioned above, condition-based maintenance is the most complicated to implement.

But, in the minds of many people, fault maintenance is urgent maintenance, maintenance that must be done right now i. I agree that in many companies losing a penny is a problem when it comes to maintenance, but I firmly believe that in those same companies maintenance teams do a great disservice by performing a lot of maintenance tasks that don't add value. Predictive maintenance can be implemented thanks to an intuitive and easy-to-use CMMS, which will make life easier for industrial maintenance technicians and will generate tables and graphs for them thanks to all the data entered by all their colleagues. However, since I am often asked questions about different types of maintenance, I decided to give a quick overview of the types of maintenance.

This type of maintenance is described as planned because it is based on well-established maintenance programs and concrete data. Preventive maintenance consists of proactively initiating maintenance tasks and plans to prevent faults from occurring. To be successful in the field of building maintenance, it is useful to understand the different types of maintenance methods that exist and how and when they are used. A next-generation CMMS, such as Mobility Work, a solution that offers an efficient analysis tool capable of collecting all the data entered by the maintenance teams themselves, aims to progressively help plants evolve towards predictive maintenance.

I don't think it's possible, fundamentally predictive maintenance is the same as condition-based maintenance, since it aims to prevent or at least mitigate the effect of a fault before the fault occurs. An efficient and effective preventive maintenance program will have a combination of all these different types of maintenance. However, the problem is that most people think of traditional time-based maintenance when they talk about preventive maintenance. .
