Rotating Machinery: Troubleshooting Analysis


Who should attend?

  • This course aims to enhance the maintenance staff skills through a clear understanding of online monitoring and failure analysis.
Audience :
  • Maintenance supervisors, engineers and all technical staff involved in rotating machinery maintenance, reliability and technical inspection.

Level : Proficiency

Course Content


      • Drop of the machine performance analysis: loss of flowrate, loss of process fluid pressure, increase of process fluid temperature.
      • Monitoring results analysis: high vibrations levels, lubrication and seal circuit parameters, abnormal values, oil quality.
      • Component failures: seal leakages, bearing damages, rotor sags, impeller cracks, misalignment.
      • Hydraulic phenomena: cavitation, unpriming, volute effect, surge.
      • Reliability improvements to increase time between failures.
      • Applications, exercises and dynamic simulator: troubleshooting analysis of pumps, compressors and turbines.

      • Process operating parameters: monitoring and analysis of the machine process data and logs.
      • Monitoring tools dedicated to the machine type: vibration monitoring, PV card indicator, rod drop, bearings temperature.

      • Material analysis: Non Destructive Tests (liquid penetration inspection, radiography, magnetic particle inspection, ultrasonic inspection). Destructive tests after rupture: hardness, welding sample test, tensile test. Analysis of the specific failure surface morphology.
      • Performance analysis: vibration analysis reports, thermographic analysis report, efficiency follow-up reports, noise analysis reports, oil analysis reports. Appreciation of standard failures.
      • Solutions to avoid failure: design parameters, stress limitations, operating parameter conditions, online monitoring.
      • Case studies: rupture and wear examinations of typical machine components (bearings, mechanical seals, rotors, crankshaft); analysis of most common failures on centrifugal pumps, reciprocating compressors, centrifugal compressors and gearbox.
        vibrations and oil analysis reports. Use of a Portable Data Analyzer, when available.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • facilitate troubleshooting investigation from failure analysis and monitoring,
  • prevent mechanical failure and reduce operating costs,
  • explain operating constraints,
  • propose improvements on machinery reliability.

Ways & Means

  • Case studies based on industrial and actual feedback.
  • Teamwork: mini projects dedicated to industrial cases.
  • Use of a dynamic simulator for centrifugal pump, reciprocating compressor, centrifugal compressor, steam turbine.
