Detailed Description of 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.

Universally maintenance is divided into two main groups, these are preventive maintenance and corrective maintenance. Preventive maintenance is mostly done on a task 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. The following are examples of preventive maintenance they 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. Unlike preventive maintenance which is classified into many divisions, corrective maintenance has only two divisions which are 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.

Failure finding maintenance, on the other hand, aims at finding the hidden failure associated with protective functions. If you want to use failure finding maintenance, you must ensure that the item you want to investigate 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. 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.

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.
