9 Causes of Unbalance

September 27, 2022

Unbalance can be caused by many possibilities such as listed below but not limited to just this list. Possible sources could be many more than those listed. Generally, if the rotor is dirty, clean it, as this alone may correct any unbalance. If it has damage fix it; if it’s loose tighten it, if a […]

3 Signs your Gearbox, Pump and Motor Shafts are not in Alignment

September 20, 2022

If your machine’s gearbox, pump and motor shafts are not in alignment, the cost of failures and repairs can be drastic. Misalignment of this nature will significantly reduce its performance and mean time between repairs, as well as the functional longevity of the gearbox, motor, and the machines as a whole! It’s important to be […]

9 Belt & Chain Storage Best Practices

September 6, 2022

A few simple practices could help to prevent damage to your spare belts and chains: Label chains and belts by type, size, number, and date stored. Label shelves in accordance with in-house MRO guidelines. Maintain constant temperature and relative humidity. Store in a clean and dry environment to prevent ingress contamination. Keep belts out of […]

Preparing for the Balancing Job: A Few Things to Keep in Mind

August 30, 2022

The following facts are principles that form the basis for the balancing of machinery. When a person determines that a rotating machine needs to be balanced, a few things should be kept in mind The vibration caused by imbalance always occurs at 1× RPM of the unbalanced rotor. The vibration is directly proportional to the […]

Are You Using Coupling Tolerances to Align Your Machines? You’re Doing It Wrong!

August 23, 2022

If we want to get into precision maintenance, we need to be aware of the differences between shaft alignment tolerances and coupling tolerances. I just recently read an article from an online Reliability Maintenance website. It’s from a well-known organization that sells training for Reliability Centered Maintenance and Condition Based Maintenance programs. The title read: […]

Is Everyone Aligned with your Company Standards?

August 17, 2022

I recently spoke to a reliability engineer who was rolling out our alignment and vibration equipment to fifteen plants across the U.S. He involved us early on in the process. His company didn’t just set aside budget money for the equipment purchase, but also enough to properly train their field service personnel in how to […]

In the field of vibration analysis, there is an abundance of technical terms. We provide definitions for some of these terms that you might hear from an engineer or technician as well as read in reports and might need further clarification. We welcome you to check out our glossary of terms relating to vibration analysis, […]

Environmental Compliance Through Efficient Work Practices: Part 3

August 2, 2022

We previously discussed in this series, Environmental Compliance Through Efficient Work Practices: Part 2. In this blog, we discuss goals for efficient work practices like bearing lubrication and fan pitch/balance. Upgrading tools and introducing more complete training should be part of any company’s operating plan, so we will see how much impact can be made by […]

1× RPM Vibration is Not Always Caused by an Unbalance, Here Are 9 Other Faults

July 26, 2022

Caution: While unbalance always causes vibration at 1× RPM, 1× RPM vibration is not always caused by an unbalance. Other problems are: Misalignment: Misalignment can cause a 1× RPM component in the data, but it also generates a 2× RPM component and sometimes an elevated axial vibration at 1× RPM. Bent/Bowed Shaft: Generally, this fault will […]

What is Machinery Installation And Why is it Important?

July 19, 2022

What is machinery installation? Machinery installation is an essential phase in every machinery’s lifecycle. It’s the first moment of bringing machinery into production. Why is proper installation necessary? The installation process has a direct impact on the machinery. It’ll determine the operating conditions in the performance and lifecycle cost. How the machine gets installed determines […]

5 Best Practices for Inspecting Steam Traps!

July 12, 2022

What is the proper technique for performing steam trap inspections? My short answer never changes. It involves two readings…one was taken a few feet upstream of the steam trap to ensure there is flow, and the other reading was taken immediately after the steam trap. If the steam trap is operating correctly, you will hear […]

In this blog, we discuss goals for efficient work practices like proper alignment and belt alignment. Upgrading tools and introducing more complete training should be part of any company’s operating plan, so we will see how much impact can be made by […]

How to Grease Your Bearings Using Ultrasound?

June 28, 2022

Inspection Technique Greasing of bearings using ultrasound, often described as best practice, helps us understand how much grease needs to be applied. Ultrasound is a good measure of friction – too little or too much grease in a bearing produces elevated friction levels. Using ultrasound, the right quantity of grease is determined by assessing the […]

4 Best Practices Leakage Assessment Steps

June 21, 2022

  Obviously, getting leakage repaired after the detection effort is done is extremely challenging and sometimes frustrating in today’s economy. But, where many plants fail, others do extremely well in managing their leakage levels. The latter plants are the ones using best practices. In conducting leak assessments four important steps come up when researching the […]

Frequency is Everything!

June 14, 2022

In the world of vibration analysis frequency is everything.  Frequencies are generated by many sources within a machine. The running speed of the machine is one example frequency; this is the velocity of the rotating element which in many cases is a drive shaft connected to an application (like a fan or a pump). Each frequency will […]

Environmental Compliance Through Efficient Work Practices: Part 1

June 7, 2022

The current business operating culture is experiencing a sea change. Some are being brought on by local and global political shifts, but more is being brought about by a worldwide pandemic and the challenges of having properly trained people available to keep equipment running as expected. Lofty goals have been promulgated in boardrooms, investor meetings, […]

What is Unbalance?

May 31, 2022

Unbalance occurs when a rotor’s center of rotation does not correspond with the center of the rotational mass. Simply stated, there is a “heavy spot” on the rotating element. Mass is seldom evenly distributed throughout a rotor. Equal distribution of mass is not required for the rotor to be “balanced.” However, the mass variations should […]
