CAUSES OF VIBRATION

1. Imbalance
2. Misalignment
3. Broken rotor bars
4. Mechanical looseness
5. Bearing faults
6. Vane wear

In contrast to Preventive Maintenance, in which critical components of the machines are replaced as per a predetermined schedule, in Vibration Monitoring, replacements are called for only when deterioration in their condition is observed through monitoring and these in-turn results in considerable savings in the maintenance and spare part inventory costs.

• Reduces unscheduled machine down time
  
• Minimises unnecessary repairs
  
• Allows maintenance and repair intervals to be extended
  
• Identifies lead time for required repairs - helps planning of maintenance
  
• Reduces spares inventory
  
• Minimises maintenance time and cost
  
• Improves product quality
  
• Increases plant safety

• Natural frequency and modal shape calculation of structure using Finite element analysis
• Machinery Problem Diagnostics
• Vibration Analysis of Rolling Element and Journal Bearings
• Gear-box analysis
• Natural Frequency, Critical Speed and Resonance Condition identification
• Vibration Signature Analysis
• Vibration Time & Phase Analysis
• Coast up and Coast down data
• Setting of acceptable Standards/carpet levels for Vibration
• Vibration Analysis of Industrial Fans and Blowers
• Ground vibration measurement
• Condition Monitoring of Electrical Motors
  
  
• In-Situ Balancing of Rotating Machine elements like
• Spindle-Chuck assemblies
• Fine Boring Machine Spindles Motor-Pulley assemblies of all capacities
• High Speed Machine Spindles
• Alternator/blower fans
• In-Situ Balancing of rotating machines are being done upto a balancing grade of G 0.4
