The term maintenance is defined differently in various industries. However, in this article, we will not base our discussion on a specific industry, however, we will explain the general meaning of the terminology as well as take you through the types of maintenance.
Universally maintenance is divided into two main groups, these are preventive maintenance and corrective maintenance. It is worth noting that if you want to apply the concept of preventive maintenance on an event, you must ensure that you do so before a failure has occurred. If you would like to apply the concept of preventive maintenance on a situation, it should be aimed at preventing a failure from happening, lower the consequences of the failure and assess 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.
If you would like to apply the concept of corrective maintenance, it is best to apply it when the failure has occurred. The main types of corrective maintenance include deferred maintenance and emergency maintenance.
In this section, we will take you through detailed descriptions of the types of maintenance that fall within 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. The beauty about time-based maintenance is that it can protect you from the failure of known parts that have been wearing out and which have known 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. This implies that under normal conditions, it will be difficult to know whether an item is still functional.
Risk based maintenance is different from time-based and failure finding maintenance since risk-based requires one to use risk assessment concept to assign the scarce resource to the ones that take much risks in the event of a failure.
There are cases where it is possible to stop an event from failing, this is where you happen to spot failures in the early stages. Condition based maintenance is ideal for preventing failures from happening since it looks for physical evidence that a failure is occurring or is about to occur.
In predictive maintenance, we pay attention to the features of an item that makes it move 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.
