With the availability and decreasing prices of technology to help diagnose rotating machinery health, machine failure should be a diminishing concern. Thermal imaging cameras can be expensive; however, these cameras have very detailed diagnostic abilities and high resolution. Reduced cost Thermal Imaging has recently become available through various sources. I recently purchased an infrared camera…

In industrial machinery, the centerpiece of vibration analysis is the ability to detect bearing problems BEFORE the bearing fails. Even more beneficial is detecting the root cause of a bearing problem before damage is done. The bearing really is the heart of the rotating machine. There’s a plethora of bearing types and designs. There…

I have been in industrial maintenance longer than I have not. A portion of that time was spent in Maintenance Management. One lesson I learned was, that in order for a team leader (or company as a whole) to be successful, the entire team needs to be successful. I tend to simplify things, maybe to…
Read MoreDoes the z axis affect alignment? In short, no it does not. There are aspects of the z axis that could affect the running of a machine, but rotational shaft alignment is not of them. What is the z axis? The X and Y axes are references to horizontal and vertical planes respectively. With regard…
Read MoreIn today’s lean manufacturing, RCM (Reliability Centered Maintenance) is becoming more prevalent. Condition Monitoring is a big part of RCM. However, continuous monitoring is typically only done on “critical” equipment which amounts to approximately 20-25% of the equipment. The other 75-80% might get picked up during vibration rounds, which will then have to be analyzed,…
Read MoreMachines vibrate for lots of different reasons-some good, others not so good. Over the next few months, we are going to write about some of the most common machinery vibration causes, and possible solutions. COUPLING MISALIGNMENT One of the most common problems in coupled rotating equipment is misalignment. Simply stated, misalignment is when the driving…
Read MoreDuring the field portion of a recent training class vibration readings were taken before and after the precision shaft alignment of a pump and motor. This was done with a hand held vibration meter with a single plane accelerometer. The readings were approximately as follows: Motor NDE V-.07, H-.07, A-.11. Motor DE V-.07 H-.07 Pump…
