Torsion Vibration Measurement and Analysis of Flue Gas Fan

Torsion Vibration Measurement and Analysis of Flue Gas Fan Torsion vibration can influence the operability and technical life of drive systems such as fan-motors or automatic trains. Typically, torsion vibration is weakly coupled (in the XYZ direction) with axial vibration when the drive system is straight. It can be nearly impossible to detect torsion vibration from axial vibration measurement because of this weak coupling. This section discusses various ways to detect the presence of torsion vibration and how to quantify torsion vibration when troubleshooting. The phrase torsion vibration...

DIY Encoder for RPM and Torsion Vibration Analysis

Torsion vibration can be difficult to detect in rotating machinery as vibration occurs in a rotating component or drive train. Torsion vibration may result in equipment damage as loads increase and machine internal timing is affected. This post is about optic sensors and the use of a Do It Yourself (DIY) encoder to detect torsion vibration. A tacho signal can consist of one or more pulses per revolution. It can be picked up using e.g. a rotary encoder placed at a free shaft end, magnetic or optic sensors for the purpose of torsion analysis. Torsion analysis can be made using other...
