EMDS Motion Camera Alerts Cement Plant

EMDS was called to evaluate the E51FN05 Fan, at an aggregate plant, which had been running smoothly until a defect in the fan bearings necessitated their replacement. Continued abnormal motion was detected around the unit, prompting EMDS to acquire and analyze Motion Amplification Video, alongside traditional velocity and acceleration vibration data. The motor and fan were mounted on a substantial concrete base, supported by below- grade caissons, and surrounded by a concrete apron serving as a walk and work platform. Moisture pressing out around the expansion joints while the fan was operating, and noticeable vibrations underfoot raised concerns. An earlier attempt [...]

Horner Electro-Mechanical Diagnostic Group – Coal Fired Power Plant Vertical Motor

At Horner Industrial Group, we take pride in our commitment to excellence and preventative maintenance solutions. Recently, our EMDS department had a significant impact on the operations of a coal-fired power plant, showcasing the vital role of hands-on data collection and analysis in preventing potential disasters. Our client, a coal-fired power plant, relies heavily on rotating equipment to maintain its operations. Every month, our vibration technician Joe Roseberry, performs vibration data collection and analysis on all rotating equipment at the plant. One critical piece of equipment under Joe’s watchful eye is an agitator, which plays a crucial role in an environmental [...]

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 [...]

From Scrap To Like New

A brick manufacturer had a large fan that pulls air, brick and cement dust thru an overhead duct system into a bag house then through the fan and up a stack. The baghouse requires cleaning frequently and during the cleaning cycle the baghouse is bypassed and the material goes through the fan. This causes buildup on the fan blades and thus an imbalance and vibration. The vibration is so severe it cracks the motor base, bearing base and fan housing. The customer has attempted to deal with this by filling the fan base with concrete, welding large angle iron to the [...]

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 [...]

Loose Motor Bases: Motor Vibration (A Simple Solution)

When analyzing motors, it is easy to read more into a problem than actually exists. This case history illustrates the need to always look for the simple solution first. While at a power plant working on a large fan, the vibration analyst requested that a large mill motor be examined. The motor had been sent out to motor shops twice. In each instance, the vibration remained high when the motor was put back into operation. Attempts were made to field balance the motor, however, they were unsuccessful. The motor continued to have amplitudes of 8 mils of vibration, all of which [...]
