VIBRATION ANALYSIS

COURSE DESCRIPTION

Condition Monitoring and in particular, Vibration 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 familiarize the attendee with methods of vibration 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.

COURSE OUTLINE

• 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 and analysis equipment.
• Vibration transducers
• Vibration meters
• Vibration analyzers

• Be able to describe and utilize vibration graphic representations
• Trend charts
• Vibration signatures or spectrums
• Time wave form data
• Orbit diagrams

• Operate an I.R.D. 350 Analyzer:
• Carry out correct set-up procedures for the I.R.D. 350 analyzer
• 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 350 analyzer, 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
