Encourage the right behavior 2. Difficult to manipulate 3. Easy to measure Condition Based Maintenance - -Vibration analysis Infrared thermography Acoustic/ultrasonic Oil analysis Electrical Shock pulse method Partial discharge and corona discharge Operational performance - pressure, temp, flow rates, etc. 3 Cautions with Preventive Maintenance - - 1. Intrusive inspections 2. Tasks must be reviewed frequently to determine accuracy 3. Equip,met is hazarded and frequently degraded by tasks Condition Based Maintenance Activities (3) - - 1. Condition Measurement 2. Condition monitoring and health assessment 3. Repair and maintenance actions Reliability Centered Maintenance - -A systematic, disciplined process to ensure safety, mission compliance, and system function Defines system boundaries and identifies system functions, functional failures, and likely failure modes for equipment and structures in a specific operating context 4 Essential Elements of RCM - - 1. Define system and required functions 2. Define functional failures and specific component failure modes that can defeat required functions 3. Prioritize the importance of the failure modes 4. Select the applicable and effective PM countermeasure for the high priority failure modes Key Players in the Work Process - -Coordinator - asset/resource Planner Scheduler Configuration specialist Craft supervisor Work performer Benchmark - % of Planned Work - - 90% CMRP CDC Benchmark - % of Schedule Compliance - - 85% Benchmark - % of Time the Right Part is Delivered - - 99% Economic Order Quantity - - 3 Key Parts of Asset Reliability - -Asset function Conditions under which Asset operates Mission time Reliabiltiy - -Probability that an item will perform its intended function for a specific interval under stated conditions Availability - -Function of reliability and maintainability Measured by degree to which an item or asset is an operable and committable state at the start of the mission when the mission is called at an unspecified time =MTBF/(MTBF+MTTR) Percentage of actual time that an asset is operated compared to how long it was scheduled to operate Cost Breakdown of Asset Life Cycle - -Design and development - 5-10% Installation - 10 -20% Operations and maintenance - 65 - 85% Disposal - 5% Key Elements of Reliability Specs - -Probability of successful performance Function to be performed Usage time Operating conditions Environment Skill or operators/maintainers Equipment Design Phase Analysis - -Reliability analysis Maintain ability analysis System safety and hazard analysis Human factors engineering analysis Logistics analysis Total Productive Maintenance Pillars (8) - - 1. Autonomous Maintenance 2. Focused Improvement 3. Planned maintenance 4. Quality maintenance 5. Training and development 6. Design and early equipment management 7. Office improvement CMRP CDC 8. Safety, health, and environment 5S Steps - -Sort Set in Order Shine Standardize Sustain (Safety) Overall Equipment Effectiveness (OEE) - -Availability x Performance x Quality Total Overall Equipment Effectiveness (TOEE) - -Utilization x availability x performance x quality Utilization - -Percentage of time equipment is used based on 24 hours per day and 365 days per year Reliability Centered Maintenance Principles - - 1. Primary objective is to preserve system functions 2. Identify failure modes that can defeat the functions 3. Prioritize function needs 4. Select applicable and effective tasks Primary Functions in RCM - -The reason the asset exists at all Secondary Functions in RCM - -Environmental integrity Safety/structural integrity Control/containment/comfort Appearance Protection Economic/efficiency Superfluous functions RCM 7 Critical Questions - -What are the functions? What are the functional failures? What are the failure modes? What are the failure effects? What are the failure consequences? What are the proactive tasks and task intervals? What are the default actions? RCM Analysis Process - -System selection and info collection System boundary definition System description and functional block diagram System functions and functional failures Failure Mode and Effects Analysis (FMEA) CMRP Logic Tree Analysis Selection of Maintenance Tasks Task packaging and implementation Continuous improvement RCM Benefits - -Reliability Cost Documentation Equipment/parts replacement Efficiency/productivity Broadband Vibration Analysis - -Broad view of machines vibration Total vibration of a machine Narrow bend trending Vibration Analysis - -Monitors total energy for a specific bandwidth of vibration frequencies More specific Signature Vibration Analysis - -Provides visual representation of each frequency component generated by a machine Ultrasonic Testing - -Leak detecti
