Condition Based Maintenance (CBM) is a maintenance strategy that focuses on the condition of equipment and systems, rather than on predetermined schedules or predetermined time intervals. This approach to maintenance is based on the idea that it is more cost-effective to repair or replace equipment when it is actually needed, rather than following a predetermined schedule. CBM involves the use of predictive and preventive maintenance techniques, such as vibration analysis, oil analysis, and infrared thermography, to detect the condition of equipment and systems. This allows for early detection of potential problems, so that corrective action can be taken before the problem becomes more serious. By monitoring the condition of equipment and systems, CBM can help to reduce the amount of downtime and repair costs, as well as increase the overall reliability of the system. CBM is an important part of any maintenance strategy, as it helps to ensure that equipment and systems are operating at peak efficiency, while minimizing the risk of unexpected downtime and repair costs.
