The workshop

This practical workshop provides a detailed examination of the detection, location and diagnosis of faults in rotating and reciprocating machinery using vibration analysis. The basics and underlying physics of vibration signals are first examined. The acquisition and processing of signals is reviewed followed by a discussion of machinery faults diagnosis using vibration analysis, and rectifying the unidentified faults. The latest approaches and equipment used together with current research techniques in vibration analysis are also highlighted in the workshop.

The training will be in preparation to the vibration institute of USA Category 1. The vibration analyst certification uses body of knowledge compliant with ISO 18436-2 and is enhanced by a job- task analysis conducted by the Vibration institute Certification Committee.

ISO 18436-2 specifies the general requirements for vibration analysis personnel who perform machinery condition monitoring and diagnostics of machines. Certification to this standard will provide recognition of the qualification and competence of individuals to perform machinery vibration measurements and analysis using portable and permanently installed sensors and equipment ISO 18436-2:2003 a four- category certification program that is based on the technical areas discussed herein.

Pre- requisites

This is not an advanced workshop but one aimed at the fundamentals. A basic knowledge of electrical and mechanical concepts would be useful.

Job Titles

  • Maintenance Manager
  • Engineering Manager
  • Reliability Manager
  • CBM Engineer
  • Facility Engineer

Coming from the following industries

  • Power Generation
  • Petrochemicals
  • Transportation
  • Automotive Manufacturing
  • Pulp & paper
  • Earth-moving (Mining)
  • Primary metals (steel Manufacturing / smelting)
  • General manufacturing
  • Process manufacturing

Vibration Analysis is used in the following objectives:

Early Detection of mechanical fatigue or breakdown

  • All rotating equipment vibrates to some degree, but as older bearings and components reach the end of their product life they begin to vibrate more dramatically, and in district ways
  • Ongoing monitoring of equipment allows these signs of wear and damage to be identified well before the damage becomes an expensive problem

Accurately monitor health of your plant machinery

  • It is a useful tool to identify unbalance, misalignment, eccentricity, bent shaft crack, mechanical looseness, journal bearings faults, rolling elements. Bearing faults, rotor rub, cavitation, electrical motor problems and gear faults.

Decrease downtime and increase savings

  • This process is generically known as ‘condition monitoring’. When used correctly, it can result in huge cost savings when compared to traditional maintenance methods
  • Traditional maintenance methods are preventive components are replaced on a fixed schedule whether worn or not and reactive maintenance in which components are repaired only after they have broken down.
  • Neither of these methods is ideal, although both are very common throughout the heavy industry sector, and both tend to incur much higher costs than those methods that use vibration analysis.
