How does preventive maintenance differ from predictive maintenance?

• A. Preventive maintenance is condition-based
• B. Predictive maintenance is scheduled based on time or usage
• C. Preventive maintenance occurs when a failure is imminent
• D. Preventive maintenance is scheduled based on time or usage, while predictive is based on condition monitoring

Answer: (D)

Preventive maintenance is a strategy that involves performing maintenance activities on equipment at scheduled intervals, often determined by time or usage metrics. This approach is designed to reduce the likelihood of equipment failure by performing routine checks, service, and necessary repairs. The intent is to keep systems running smoothly and to prevent unplanned downtime. On the other hand, predictive maintenance relies on condition monitoring and real-time data to predict when maintenance should be performed. This type of maintenance aims to conditionally address potential issues before they lead to equipment failure, using tools like vibration analysis, thermography, or oil analysis to gauge the health of equipment at any given moment. The distinction between the two methods is crucial for effective maintenance management; preventive maintenance adheres to a fixed schedule, while predictive maintenance is more dynamic and adjusts based on the actual condition of equipment. This understanding aids in selecting the right approach based on the operational requirements and equipment lifecycle, ultimately improving efficiency and reducing costs.
