Preventive Maintenance – Concept, what it is for and types

We explain what preventive maintenance is, what it is for and what types exist. Also, its role in computing.

Preventive Maintenance
Preventive maintenance is often recommended by the appliance manufacturer.

What is preventive maintenance?

When we speak of preventive maintenance or prior maintenance, we refer to the set of actions of review and cleaning of equipment and facilities, which allow anticipating any type of failure or inconvenience through the preservation of its optimal state of operation.

In other words, preventive maintenance encompasses the different measures that can be taken in anticipation of equipment and machinery damage, rather than waiting for it to occur and then fixing it. That is its fundamental difference with corrective maintenance, which would be what is done to equipment that already shows damage or flaws.

Preventive maintenance usually consists of various methods of preservation of components and their functionality, often recommended by the manufacturer of the device, or on the advice of specialists and experts in the field.

What is preventive maintenance for?

As the name implies, the primary goal of preventive maintenance is prevent damage, or at least delay its appearance as much as possible, thus avoiding or at least mitigating its consequences.

To do this, the replacement measures (change of worn parts, burnt lubricants, etc.), addition (incorporation of missing substances, etc.) or cleaning (elimination of residues, etc.) that are necessary to extend the life of equipment and toolsespecially when it comes to sophisticated material.

Types of preventive maintenance

Predictive maintenance assesses the condition of the equipment.

Usually three possible types of preventive maintenance are distinguished, depending on their specific performance criteria:

  • Scheduled maintenance. It refers to the maintenance tasks that must be carried out when a certain milestone or limit is met in the operation of the equipment. For example, an oil change is recommended for cars every 10,000 kilometers driven.
  • Predictive Maintenance. It is one that is dedicated to evaluating the status of the pieces or components of a piece of equipment, in order to determine when and in what way preventive maintenance tasks should be carried out. For example, computer overhaul and maintenance programs.
  • Opportunity maintenance. In this case, maintenance occurs when the equipment is not in use, that is, taking advantage of moments of free use. For example, if we take the car to the workshop for a repair, it is likely that the opportunity will be taken to do other essential maintenance work.

Preventive maintenance in computing

In the case of computing, preventive maintenance covers both the operation of the computer software and hardware, since both aspects have a decisive influence on the operation of the system, which in turn translates into speed and agility of the system. .

  • Regarding software, there are preventive maintenance programs that scan the system to determine and correct errors and debris left by everyday use, such as invalid registry entries, missing shortcuts, and other such details. Defragmentation of the computer is also common, which consists of reorganizing the information on the hard disk in such a way that it does not take more time than is strictly necessary.
  • In terms of hardwareOn the other hand, preventive maintenance of this equipment is reduced more than anything to cleaning the exterior and the surroundings, to prevent the accumulation of dirt and dust inside the equipment and its peripherals. The internal cleaning of the computer is usually carried out by specialized technical personnel.
