Maintenance Flashcards
What is maintenance in the context of engineering?
Maintenance is the process by which machines and equipment receive the appropriate care to keep them in good working order.
Maintenance is considered the ‘healthcare’ of machines and equipment.
What is the main purpose of regular maintenance?
To ensure that all equipment is operating at 100% efficiency at all times.
Regular maintenance helps detect and correct minor problems before they become major issues.
What is planned maintenance?
Planned maintenance refers to any maintenance activity that is planned, documented, and scheduled to reduce downtime.
It ensures that all necessary resources are available to carry out maintenance activities.
What are the two main types of planned maintenance?
- Planned preventive maintenance (PM)
- Planned unscheduled maintenance
PM involves scheduled maintenance before failures, while unscheduled maintenance focuses on quick repairs after failures.
List three advantages of planned maintenance.
- Reduces maintenance costs
- Improves overall equipment performance
- Decreases downtime
What is reactive maintenance?
Reactive maintenance addresses problems when they arise, triggered by equipment malfunctions and failures.
This approach is suitable for non-critical and low-cost equipment.
List two advantages of reactive maintenance.
- Fewer staff members needed
- No planning time necessary
What is preventive maintenance (PM)?
PM is the regular and routine maintenance of equipment and assets to prevent costly unplanned downtime from unexpected equipment failure.
What is condition-based monitoring (CBM)?
CBM is the process of monitoring machinery parameters during operation to identify significant changes that may indicate developing faults.
List three advantages of condition-based monitoring (CBM).
- Improves worker safety
- Optimises maintenance intervals
- Reduces the cost of asset failures
What does MRO stand for in maintenance terminology?
Maintenance, Repair and Operations/Overhaul.
MRO encompasses equipment, tools, and activities associated with daily operations of a business.
Give two examples of MRO activities.
- HVAC maintenance
- Facility lighting maintenance
What is operations monitoring?
Operations monitoring involves observing the performance of machinery over time by collecting key system performance metrics.
What does repair mean in a maintenance context?
Repair means responding to the breakdown of equipment and undertaking work to correct the problem to return the equipment to a working condition.
What is decommissioning?
Decommissioning is the process of removing something from active service.
This can involve putting facilities into storage, repurposing, or demolition.
What is the purpose of servicing machinery?
Servicing ensures machinery operates productively and safely, preventing dangerous emissions or parts that could fail.
Fill in the blank: The cost of regular maintenance is very small when compared to the cost of a major _______.

What is shutdown maintenance?
Shutdown maintenance can only be performed while equipment is not in use, often due to the nature of the defective part.
