Vibration measurement and analysis

Vibration measurement and analysis

Vibration measurement and analysis can identify most mechanical faults in rotating machinery, such as imbalance, misalignment, looseness and even lubrication and bearing defects. All of these faults produce their own particular vibration signatures which our skilled engineers can recognize as potential faults at the very early stages. Vibration analysis is a significant aid in any predictive maintenance program.

Vibration data gives an insight into the design, base frame stability, installation etc. It is easier to resolve these problems at the initial stage before it becomes chronic and starts affecting other components in the machine other than the problematic area.

As shown in the plot below the failure rate is very high at the initial stage of the machine life span. Thus, the vibration data collection and eradication of the root cause of the problem at this stage is indispensable. It is a proven fact that most machines that survives infancy continues to operate for a longer period of time. Moreover vibration data can be used to monitor the health trend of the equipment.

Data sampling of Primary & Secondary Signals:

The following parameters will be sampled:
  • Rotating Machinery bearing housing vibration analysis
  • Overall bearing housing Temperature
  • Motor Ampere’s consumed
  • Machinery Load Conditions
  • Centrifugal Fans & Pumps (Dampers & Value opening/ operating %
  • Permanent marks for sampling @ Load zone
  • Generating “Asset Information Sheet”

Scope of work:

  • Identification of vibration measurement locations on your machine.
  • To carry out vibration measurements in the horizontal, vertical and axial directions at each selected bearing locations.
  • To plot vibration profiles on the relevant locations and to carry out frequency analysis.
  • To classify the machine health condition as Excellent, Good, Normal, Alert, Alarm and Dangerous.
  • To interpret the vibration data and identify the defects and inaccuracies in each machine.
  • To prepare Action Plan for maintenance / corrective actions.
  • To submit detailed Report on the Maintenance actions, corrections required.
