This month we are spotlighting Steve Bigler. He works at Kankakee Industrial Technology, a division of Decatur Industrial Electric. He has been with the Company for over 17 years. He performs service repairs on welders, motors, generators, pumps and more. You may also see him at your facility when he is out on service calls. In his free time he enjoys gardening, landscaping, and spending time with his wife.
When establishing current demodulation band alarms for belt frequencies associated with a 2-pulley belt driven system, remember both the 1x belt frequency and 2x belt frequency should be taken into consideration. Initial band alarms for the 1x belt frequency are recommended at baseline + 10% for caution and baseline +20% for severe. Initial band alarms for the 2x belt frequency are recommended at baseline +25% for caution and baseline +50% for severe. Based on test results from known defects, analysis of the 1x belt frequency focuses more on the system alignment while 2x belt frequency focuses more on belt condition and looseness.
For more information on establishing band alarms for mechanical defects read the short article "Advanced Spectral Analysis" found on the PdMA website.
Does this sound familiar? Run a motor to failure. Buy a new motor. Rinse and repeat.
When a motor runs until failure it causes unplanned production downtime and emergency maintenance. At that point, the cost to repair the motor is generally not economical and a new motor has to be purchased. As the preferred vendor for this customer, we instituted a tracking spreadsheet to note when a motor was removed prior to failure and the cost to repair versus running a motor to failure and the cost to replace. The difference in cost proved how predictive and preventative maintenance practices offered through Decatur Industrial Electric can extend motor life and increase reliability.
