Vibration Sensor Mounting Tips

| | |

By on September 13, 2018

Accelerometers by nature are sensitive tools. This sensitivity is heavily influenced by how the sensor is mounted. Standard accelerometers are mounted several ways based on need and application. Typical route-based data collecting will be done with a rare earth magnet. The magnet can be either flat or a two-pole type. This provides good data with […]

What is the Difference between Unbalance and Runout?

| |

By on September 5, 2018

Unbalance and runout are two terms that we hear frequently in the predictive maintenance community. Both unbalance and runout can be serious issues and need to be addressed to prevent inefficient functioning and damage to machines. Unbalance occurs due to corrosion, erosion of the fan wheel, or if a correction weight is removed. Runout occurs […]

How to Measure Your Machine’s RPM

| | |

By on September 4, 2018

Determining the RPM (revolutions per minute) of your machine is an important part of conscientious condition monitoring. Significant loss of time and productivity can occur if your machinery is not operating at the correct RPM. That’s why it is imperative to be able to quickly and accurately determine the RPM. In this post we will […]

Condition Monitoring Basics: The Importance of Routes

By on July 31, 2018

One of the basics of condition monitoring is establishing routes so that you can efficiently check the diagnostics of all your machines in an orderly, structured way which does not disrupt the daily tasks of other workers in your plant. Routes help to guide the mechanic to the next machine in a logical order rather […]

Using the Smart Machine Checker as a Lubrication Tool

| | | | |

By on July 10, 2018

The Fixturlaser Smart Machine Checker (SMC) is a great mechanic’s tool, for evaluating the overall health of rotating machinery.  But did you know it’s also a lubrication tool for greasing bearings?  Let me explain. One of the vibration measurements in the SMC is called Bearing Defect Factor.  The Bearing Defect Factor is a measurement of […]

At the wrap up of a recent Hawk/SMC class the discussion was around what rotating assets to collect vibration data on going forward. The conversation quickly turned to a few keys assets that had the ability to impact large percentages of the downstream processes. The area technicians said that even though the machine was very […]

By on March 13, 2018

When using the Fixturlaser Smart Machine Checker (SMC) or any of VibrAlign’s Condition Monitoring Tools, there are typically only two variables you need to know for an accurate diagnosis of your machine.  You need the horsepower of the motor and the correct rotating speed.  This information will usually be stamped on the motor data plate.  […]

The Soft Foot Primer (Part 2) Vibration and Alignment Problems Related to Soft Foot

| | | | |

By on February 26, 2018

Most industrial maintenance mechanics who are involved with precision shaft alignment are familiar with the phenomenon of soft foot.  From an alignment standpoint, soft foot causes: Changes in alignment values, between when the hold down bolts are loose, and when they are tight. Non-repeatability in alignment measurements, especially if the bolts are not tightened in […]

Soft Foot! Or Are You Just Pulling My Leg?

| | | | | |

By on February 12, 2018

It’s no joke that many machines operate with high levels of vibration due to soft foot.  These same machines often have a decreased life span due to this condition. Soft foot is a condition that should be eliminated during the precision shaft alignment process, if you’re performing proper alignments at all.  This condition can manifest […]

By on December 27, 2017

James Pekarek, one of our trainers, wrote a blog entitled “Performing Alignment Checks as Part of Your Preventive Maintenance”. https://vibralign.com/shaft-alignment/performing-alignment-checks-part-preventive-maintenance/ It is a great article, and good advice.  I recently shared this blog post, and the advice, with a customer of ours.  Here’s why. I taught a training class at a large water plant in […]

I Just Changed My Motor Bearings and They’re Bad Again!

| | | | |

By on December 20, 2017

When performing vibration analysis, it is observed that machines with VFD drives have a more frequent occurrence for changing motor bearings.  If you’ve been diligent in the installation and maintenance of these machines, ensuring the alignment and balance are within specification and the bearings are properly lubricated, but still have frequent bearing failures, it may […]

By on November 1, 2017

For years, vibration analysts have depended upon the ISO Vibration Severity Chart for the determination of machinery health.  Typically, this chart provides a level of certainty that would allow the analyst to look at the vibration levels, and if acceptable, move onto the next machine for analysis.   Some defects are determined in the waveform […]

By on October 26, 2017

One of the hallmarks of a good maintenance technician is the ability to troubleshoot – not just using vibration tools, or volt meters, or laptops with Ethernet plug-ins, but the ability to troubleshoot machinery in their minds.  In other words, the ability to visualize what the problem might be. “Fix the easy things first” is […]
