Rolling stand vibration analysis - Issues with data collection Mill stands have had manual vibration data collection conducted monthly since 2010 and although this method was beneficial in finding issues such as alignments, looseness, bearing and gear wear We were still having delay events caused by faster-moving defects in between manual readings.
What is important to know is that vibration monitoring techniques that are widely used at present generate the domain of informative features of equipment defects in a form that is extremely problematic for automatic systems. The main issue is...
Electrical failure modes can be divided into four main categories. This tip will briefly discuss these categories and their associated thermal patterns to help the field thermographer better understand and identify thermal anomalies found in the field...
If you are used to vibration analysis, you may be wondering whether ultrasound analysis allows you to diagnose faults as well. Adrian Messer explains…

Ensuring assets are reliable means leaning heavily on condition-based maintenance strategies.......
The concept is based on friction. If a bearing needs grease, there is an increase in friction and, therefore, an increase in noise. What we want to see happening is…
Some people wait until a holiday or a plant shutdown to use ultrasound to look for air leaks. When the plant is quiet, they can hear the leaks with their own ears, but with ultrasound…
The Poor Man’s ODS will be a five-part series; today's tip is Part One: the introduction to the Poor Man’s ODS. ODS stands for operation deflection shape analysis; this is a study of how a machine is moving in relation to a fixed reference point…
