OTSVMA001 VIBRATION MEASUREMENT & ANALYSIS - Mechanical

VIBRATION MEASUREMENT AND ANALYSIS (REF:OTSVMA001)

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.

Days 3 - 5

Operate an portable Analyser:

Carry out correct set-up procedures for the 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 analyser 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
