The term maintenance is defined differently in various industries. Here, we will not talk about maintenance as used in specific disciplines, however, we will offer the general meaning of the term and also discuss the different types of maintenance.
It is worth noting that there are two main types of m, 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. We mostly use preventive maintenance to prevent a failure from happening, minimize the effects 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.
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.
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. 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. Furthermore, when we use time-based maintenance, we assume that failure is age-related and a clear service can be determined.
Unlike time-based maintenance, failure finding maintenance aims at noticing the hidden failure of an item which is associated with protective roles. It is worth noting that this type of maintenance is not necessary until 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.
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.
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. Therefore, when you understand the types of maintenance, you will be able to know the types to adopt in your operations depending on the situation at hand.
