Trainer for the study of mechanical vibrations

VBR-01/EV

Vibration diagnosis is a technique for checking the condition of rotating machines (e.g. mechanical). By performing this procedure regularly, you will be informed in advance about potential failures before the machine reaches the breakdown condition (that is, before having to apply corrective maintenance). This is of a great advantage for large motors and generators, avoiding expensive overhauls. It is also very important for those critical machines (sometimes even low power machines) that can stop a complex and costly industrial process. The periodical measurement, recording the values and evaluating the collected data performs one of the most important functions of PREVENTIVE MAINTENANCE. Briefly, with the information supplied by this technique, you decide the optimum moment to stop the machine for repairs; you control the situation, instead of being “controlled” by the machine condition.

 

Training program

  • The importance of vibration measurement.
  • Study of the factors that can cause vibration of the rotating parts.
  • The vibration measuring parameters used in industry: overall RMS and PEAK velocity, overall RMS and PEAK acceleration, overall RMS and PEAK displacement, bearings fault detection, acceleration enveloping measurement.
  • Influence of the RPM on the measured parameters.
  • Selecting the optimum machine points for the vibrations checks.
  • Preparing the surface of the measuring points. Precautions to be taken.
  • The vibration measurement instrument: input sensors, outputs, measured parameters.
  • Classical industrial measures on rotating machines related with mechanical vibrations: unbalanced masses, axis misalignment, machine looseness.
  • Evaluation of the collected data and further actions to be taken
