Machine condition monitoring vibration analysis

Vibration analysis allows you to detect early signs of machine failure/deterioration. This allows your technicians to replace or repair machinery before catastrophic system functional failure takes place.

A trained vibration analyst can easily understand the basics of vibration analysis as well as the failure modes of the equipment.
Predictive maintenance helps in preplanning all maintenance tasks as well as any unavoidable downtime.
Vibration data acquired from reactive maintenance can help replace or repair the parts which are exhibiting signs of wear and tear.

Vibration Analysis in Maintenance

If you engage in maintenance practices, you will want to ensure your technicians can make the replace-or-repair decision before complete system failure of key components takes place. The easiest way to manage this risk is with vibration analysis.

It is well known that, all rotating equipment vibrates and as components begin to either reach the end of their serviceable life or begin to deteriorate, they start to vibrate in unique ways, and they may also start to vibrate more.

This is why it’s so important to consistently monitor your equipment. Using vibration analysis, qualified technicians are able to identify any of the known failure mode indicators of wear and tear. Also, they can assess the possibility of future damage before it becomes unfixable and of a financial impact to the business.

Where can Vibration Analysis help technicians?

Now that we’ve briefly explained the importance of vibration maintenance, let’s look at exactly how vibration analysis helps in maintenance. Key components that can vibration monitoring and analysis can detect problems with include, but not limited to:

Misalignment
Bearing health
Impeller operational issues
Gear defects
Bent shafts
Component or machine balances
Loose bolts, mounts, fasteners, etc.
Electrical issues
Process flow issues

Avoid serious equipment failure with vibration analysis

Essentially, vibration analysis will enable you to evaluate equipment health to avoid failures. How? Well, with modern vibration analysers you can get a comprehensive snapshot of what is happening with a particular machine.

This is possible because many modern vibration analysis units are able to display the complete vibration frequency spectrum and time of three axes at the same time.

Of course, for this information to be of any value, the person analysing the data has to understand the basics of vibration analysis, the failure modes of the equipment under analysis and how to apply this.

The vibration data and what to do with it

When gathering data, you want to ensure you’re gathering the complete data set. In other words, you need to get a full vibration signature for the vertical, axial, and horizontal axes on the driven equipment as well as both ends of the motor. And ensure that you will be able to resolve any indications of failure from the components within the asset.

Sometimes busy personnel may only get a read on one axis and this is problematic because oftentimes the problem is only one of the three axes. So, if you don’t test them all, there’s a good chance (1 in 3) that you’ll miss the problem.

And since unexpected machinery failure usually harms the vibration program credibility, this can result in an unfixable problem. On the other hand, careful and comprehensive vibration analysis can predict problems.

In predicting problems, it makes it easier to successfully carry out beneficial predictive maintenance.

Thermography tests

The Infrared thermography service is available to a wide range of industries and has numerous applications.

The Infrared thermography service is available to a wide range of industries and has numerous applications. Infrared thermography as a predictive maintenance inspection technique is a widely-recognized and effective non-destructive (NDT) testing tool used often to check electrical and mechanical systems, buildings, roofs, and facilities. IR is also used to improve manufacturing processes and is utilized in R&D applications.

A thermal image (thermogram) is a digital representation of a scene and a measure of the thermal radiation emitted by the pictured objects. Thermal images are captured via thermographic cameras, which are devices capable of sensing this radiation in the form of infrared light. Mano Enterprises only uses high resolution FLIR Cameras for our survey work.

Typical applications include:

Electrical Surveys – Electrical panels, distribution boards, transformers, HV switchgear etc
Mechanical Surveys – Motors, fans, pumps, gearboxes conveyors etc
Refractory – Boilers, incinerators, thermal oxidisers, freezers
Process – Production processes
Buildings – Heat loss, water leaks etc

Mano Enterprises Infrared Thermography service engineers have at least 20 years experience in this field. All surveys are carried out to the highest safety standards under a Permit to Work with detailed Risk and Method statements.
