Machinery Fault Diagnosis

by Hamid Karimi and Mohammad Moshtaghi

Vibration analysis is a valuable technique in machinery fault diagnosis. Although lesser time is spent on the acoustic emission technique (AET) in comparison to vibration to make it applicable in industries, many years ago, listening to machine sounds using a screwdriver or a sound scope was the first step a technician took to detect a fault in machinery.

The Absolute Basics of Orbit Plots and Centerline Plots

Have you ever wondered where orbit plots and centerline plots come from? Have you wondered what they mean and how they provide diagnostic information about the bearing and rotor? In this highly visual presentation we will provide an introduction to the proximity probe measurements and then use a software simulator to demonstrate exactly where the orbit and centerline plot comes from. If you have any involvement with sleeve bearing machines (e.g. steam and gas turbines), then this Webinar should be a real eye-opener.
