Adding vibration monitoring can lead to extended bearing life, and ensure your bearings reach their L10 potential. Vibration velocity measures in inches per second (IPS) how the equipment in question is being fatigued from vibration, ultimately influencing its longevity. The standard IOM (Installation, Operations, and Maintenance) manual recommends keeping vibrations under .124 inches per second for industrial fans operating in the installed state.
Proper Vibration Monitoring for Extended Bearing Life
Vibration monitoring is a straight-forward process of drilling and tapping into the bearings with vibration sensors at up to three key locations per bearing: vertical, horizontal and axial. That’s where it’s most important to keep them under the recommended .124 inches per second.
Drilling and Tapping for Vibration Monitoring
It’s common to focus on the vertical and horizontal angles as the two most critical areas where vibration is likely to show up. At each location drill a port into the bearing, and tap in with the vibration sensor. Once the two or three vibration sensors are installed, you’ll connect them into the control loop to the control room. As a result, you’ll always pick up any vibrations at your bearings.
