Predictive and Preventative Maintenance Concepts

What is the primary purpose of preventative maintenance?

• To fix equipment after it has completely failed.

• To perform maintenance only when sensors indicate a problem.

• To regularly perform maintenance on equipment to reduce the likelihood of failure.

• To replace equipment with new models before any issues arise.

What is a key advantage of implementing routine inspections as part of preventative maintenance?

• It eliminates the need for any future repairs.

• It allows for the discovery of issues before they escalate or cause a breakdown.

• It guarantees that equipment will never require replacement.

• It significantly reduces the initial cost of equipment purchase.

How is breakdown or reactive maintenance characterized?

• Maintenance performed based on scheduled inspections.

• Maintenance performed on equipment that is still fully functional.

• Maintenance performed on equipment that has already failed and is unusable.

• Maintenance performed using advanced sensors to predict future failures.

What is the main goal of predictive maintenance (PdM) techniques?

• To perform maintenance on a fixed schedule, regardless of equipment condition.

• To repair equipment only after it has completely broken down.

• To determine the condition of in-service equipment to predict when maintenance should be performed.

• To replace all equipment components annually to prevent failures.

What is a significant long-term advantage of predictive maintenance compared to scheduled preventative maintenance?

• It is always cheaper to set up initially.

• It eliminates the need for any human intervention in maintenance.

• It allows maintenance to be performed only when truly needed, preventing over-maintenance.

• It ensures that equipment will never experience a breakdown.
