What You Need to Know about Types of Maintenance

The term maintenance is defined differently in various industries. If you want to understand what maintenance is all about including the types of maintenance, then you are in the right place.

The major divisions of maintenance are corrective maintenance and preventive maintenance. Preventive maintenance is mostly done on a task before a failure has occurred. Besides, the task may be aimed at preventing a failure, lowering the consequence of the failure as well as assessing the risk of the failure occurring. In order to understand preventive maintenance, it is best to go through the types which include time-based, failure finding, condition based, predictive and risk-based maintenance.

On the other hand, we conduct corrective maintenance when the failure has occurred. The following are the types of corrective maintenance, they include deferred maintenance and emergency maintenance.

Here are the descriptions of the types of preventive maintenance. The main role of time-based maintenance is to change or renew a product in order to restore its reliability at a fixed interval, time and usage without minding its condition. In most cases, time-based maintenance is used to shield against the failure of wearing parts which are known to have predictable mean time between failure. In time-based maintenance, users tend to assume that the failure of a service or product is age-related.

Unlike time-based maintenance, failure finding maintenance aims at noticing the hidden failure of an item which is associated with protective roles. The main feature of failure finding maintenance is that it is only used when something has failed. Though failure finding maintenance is vital, it is impossible to use to determine whether a device is functioning under normal work conditions.

When you want to apply risk-based maintenance on an item, you will have to use risk assessment methodology to assign the limited resources to those that carry the most risks when a failure happens.

Suppose you find that something is in the early stages of failure, you may take action to avoid the consequences of failure. If you are looking for a strategy that can stop failure from happening, you may consider using condition based maintenance as it focuses on the physical evidence that an event is about to fail.

Predictive based maintenance is viewed as advancement to condition-based maintenance where a number of potential parameters sourced from online sensors to determine if an item is deviating away from normal operating conditions and heading towards failure. The types of maintenance discussed in this post are vital as they can assist companies to know the solutions to the situations they are facing.
