Advanced Diagnostic Services and Preventative Maintenance

A major steel mill was looking to upgrade their maintenance practices thru predictive maintenance vibration analysis. There were several meetings with Brad Barton of Horner’s Electrical Mechanical Diagnostics Service (EMDS) group to identify equipment and understand their expectations. The EMDS reporting was covered in depth, a vibration collection route was laid out and frequency of reporting established. The machines identified ranged from 10,000 hp AC motors to smaller AC and DC motors in the range of 100hp up to 1250 hp as well as gearboxes. Horner’s field service group installed remote accelerometers on equipment deemed not safe for personnel to enter [...]

Motor Vibration: Things Are Not Always As They Appear

Three pumps sat beside one another on a concrete foundation. Two of the motors on the pumps operated with low levels of vibration. The third motor had high levels of 120Hz vibration. As with the previous case, when the good motors were put in the third location, the 120 HZ vibration was high. A resonance test was performed and it was discovered that where the vibration levels were high that the foundation had a 120Hz vertical resonance that was not present under the other two motors. When the foundation under the bad location was jack hammered out, it was discovered that [...]
