Course Objectives

Understand Vibration and the measurement and analysis of the vibration.

Course Description

Condition Monitoring and in particular, Vibration Measurement and Analysis have become increasingly important in maintaining the reliability and efficiency of plant machinery during the last 20 years, due to escalating running costs.

The aim of this course is to familiarise the attendee with methods of vibration measurement and analysis and to make them aware of the concept of vibration, its causes, and consequences should the vibration continue and be allowed to increase.

Who Should Attend

The course is targeted at technicians and engineers involved in the operation maintenance of rotating machinery. Experienced maintenance specialists also benefit from attending this course, as will those managers concerned with maintenance, scheduling and repair aspects of rotating machinery.

Pre-Requisites

All Attendees should have a sound engineering background.

Course Outcome

At the end of this course you will be able to measure and analyse vibration.

Course Outline

Days 1 - 5

• Introduction
• Introduction to the concepts of vibration as related to rotating equipment.
• Define vibration terms and units of measurement.
• Be able to state the common causes of machinery vibration.
• Describe standard types and applications of vibration, measurement and analysis equipment.
  • Vibration transducers
  • Vibration meters
  • Vibration analysers
• Be able to describe and utilise vibration graphic representations
  • Trend charts
  • Vibration signatures or spectrums
  • Time wave form data
  • Orbit diagrams

Days 6 - 10

• Operate an Vibrotest 60 Analyser:
  • Carry out correct set-up procedures for the Vibrotest 60 analyser
  • Obtain unfiltered amplitude readings in velocity and displacement
  • Obtain filtered amplitude readings in velocity, displacement and frequency
  • Using vibration identification and severity charts provided, be able to predict probable causes of problems in equipment operation
• Apply the knowledge and practical skills gained, to carry out single plane balancing using the Vibrotest 60 analyser, strobe light and rotor kit; i.e.
  • Take necessary readings of amplitude, frequency and phase
  • Construct a vector diagram using the data
  • Apply the new weight and position data calculated to the rotor
  • Take the new readings of amplitude, frequency and phase and compare with original
  • Repeat the sequence as necessary
