Read the first 6 Preventive and Predictive Maintenance flashcards as text
What is the primary difference between preventive and predictive maintenance?
Answer: Preventive follows fixed schedules; predictive uses condition monitoring data
Preventive maintenance performs tasks at predetermined intervals; predictive maintenance monitors actual condition.
What role does motor current analysis play in predictive maintenance?
Answer: Detects electrical and mechanical faults by analyzing current waveform variations
Motor current signature analysis detects both electrical defects and mechanical problems by analyzing current patterns.
What is the purpose of preventive maintenance optimization (PMO)?
Answer: To evaluate existing PM tasks for relevance, effectiveness, and interval optimization
PMO reviews assess each PM task to determine if it is valid, effective, performed at the right interval, and cost-justified.
What is the significance of the P-F curve in predictive maintenance design?
Answer: The progression from detectable potential failure to functional failure
The P-F curve shows how condition degrades from first detectable change to functional failure.
What is the role of a CMMS in supporting PM and PdM programs?
Answer: Automates PM scheduling, stores PdM data, manages work orders, and provides analytics
CMMS is essential for managing PM schedules, tracking PdM data, generating work orders, and maintaining equipment history.
What is condition-based monitoring of electrical systems?
Answer: Using technologies like insulation resistance testing and thermography to assess electrical health
Electrical condition monitoring uses various techniques to assess the health of electrical components.
