PROGRESSIVE MANUFACTURERS HAVE CHANGED THEIR MAINTENANCE PRACTICES

BECAUSE THEY BENEFIT FROM:

º Reduced Maintenance Costs
º Increased output through reduction of down-time
º Greater safety and environmental protection
º Increased product quality
º Increased costumer service
º Longer operating lifetime of expensive equipment
º Significant energy saving

GOALS OF RELIABILITY-BASED MAINTENANCE
• Elimination of machinery breakdowns
• To provide information regarding plant production capacity based on the status of plant machinery
• To minimize labor costs through management’ s commitment to elimination of machinery failures
• To anticipate and carefully plan for maintenance needs
• To provide reasonable and predictable work hours for maintenance employees
• To allow Maintenance and Production to function as partners to schedule and maintain plant production capacity
• To increase profits by incurring significantly lower plant maintenance costs

COMPONENTS OF RELIABILITY-BASED MAINTENANCE:
PROACTIVE MAINTENANCE

Proactive maintenance uses a variety of technologies to maximize the operating lifetime of your machinery. Reactive maintenance is virtually eliminated.

Maximum returns are obtained by identifying and correcting the root causes of machinery failures.

The proactive philosophy of maintenance incorporates features of preventive and Predictive maintenance.

New and rebuilt equipment is tested against stringent specifications to ensure the quality of parts and labor.

Precision alignment and balancing are performed to maximize equipment life.

Applications
Periodic vibration monitoring may be used on all rotating and reciprocating equipment. Analysis of vibration data can detect and differentiate problems with rotor related sources ( rotor behavior and forces at play)
1. Unbalance Static, couple, dynamic or combined
2. Misalignment, Angular, parallel and combined
3. Bent shaft
4. Rubs
5. Rotor- casing
6. Rotor-product or moved fluid ( when dense or solid)
7. Shaft-sleeve bearing
8. Gear coupling-jaws
9. Belt-pulley
10. Sliding ( instead of rolling) elements
11. Rolling elements themselves onto raceways ( through lubricant film)
12. Rolling elements and retaining cage
13. Fluid and casing or piping
14. Eccentricity
15. Whirl ( of shaft or of the shaft within a fluid-film bearing) and whip
16. Torsional vibration

Process related sources ( what the machine does)
1. Hydraulic or aerodynamic forces
2. Blade / vane pass ( BPF) or blade rate ( BRF) vibration
3. Eccentricity relative to casing
4. Rotor mesh ( lobes or screws)
5. Cavitation, recirculation, turbulence, stonewalling, surging,
6. Compressed fluid wave or pulse ( pipes, etc) , turbulent flow
7. Reciprocating forces ( can come close to shock)
8. Shock ( presses, etc)

Drive related sources

1. Electromagnetic torque pulses from a motor and the interaction between armature and stator components, rotor-bar and slot pass frequency
2. Pulses used to recreate Variable Frequency altered electrical line frequency
3. Coupling problems ( lock-up, wear, etc)
4. Belt or chain drive w. eccentricity, belt problems, belt slip, cogs
5. Gear mesh and gear problem related vibration
6. Hydraulic or aerodynamic forces from gas, steam or water turbines
7. BPF ( Blade Pass Frequency) from turbines
8. Reciprocating forces from engines, unbalanced cam action
9. The most easily recognized of these are looseness and resonance.
10. Critical speeds of a rotor could be assigned to resonance
11. Oil whirl on sleeve bearings

Reactive Problems
1. Dynamic misalignment ( occurring from loads moving component positions)
2. Resonance
3. Looseness ( really a change in response due to lessened stiffness)
4. Instability ( rotor, hydraulic, oil film, other)
5. Base and retaining / supporting mechanism or structural problems
6. Distortion from pipe strain
7. Transmitted vibration ( structure borne transmission from nearby machines)

Many other problems normally associated with machinery. Awareness of the vibration level and condition of monitored equipment allows outages to be scheduled and prevents catastrophic failures.
