Corrective (or) Break down Maintenance  Scheduled Maintenance  Preventive Maintenance  Predictive Maintenance defination and difference

Corrective (or) Breakdown Maintenance:

1. Definition: Corrective maintenance, also known as breakdown maintenance, refers to the repairs and actions taken to restore equipment or systems to their normal functioning after a failure or breakdown has occurred.

Scheduled Maintenance:

1. Definition: Scheduled maintenance involves performing routine inspections, servicing, and repairs on equipment or systems at predetermined intervals to prevent failures and ensure their optimal performance.

Preventive Maintenance:

1. Definition: Preventive maintenance refers to the proactive measures taken to prevent equipment or system failures by regularly inspecting, cleaning, lubricating, and replacing components before they reach their failure point.

Predictive Maintenance:

1. Definition: Predictive maintenance involves using advanced technologies and techniques to monitor the condition and performance of equipment or systems in real-time. This allows for the prediction of potential failures and enables maintenance activities to be scheduled before any breakdown occurs.

Difference between Corrective, Scheduled, Preventive, and Predictive Maintenance:

1. Corrective maintenance is reactive and is performed after a failure or breakdown has occurred. It aims to restore the equipment or system to its normal functioning.

2. Scheduled maintenance is performed at predetermined intervals, regardless of the equipment's condition, to prevent failures and ensure optimal performance.

3. Preventive maintenance is proactive and aims to prevent failures by regularly inspecting, cleaning, lubricating, and replacing components before they reach their failure point.

4. Predictive maintenance uses advanced technologies to monitor the condition and performance of equipment in real-time. It allows for the prediction of potential failures and enables maintenance activities to be scheduled before any breakdown occurs.

In summary, corrective maintenance is performed after a failure, scheduled maintenance is performed at predetermined intervals, preventive maintenance aims to prevent failures, and predictive maintenance predicts potential failures and schedules maintenance activities accordingly.
