How to become an expert in Vibration Analysis

[@ashshettyar]

Beautiful explanation sir , please keep sharing your knowledge

[@coltruiz7126]

Can I use this device in marine engine vibration analysis? Where was the best location to put the probe? Can I put it on the engine footing/mounting? Thanks

[@AdashCompany]

Our vibration analyzers can be used on any rotating machinery, therefore also on marine engines. There are actually hundreds of these Vibrio M devices on all kind of vessels worldwide. Sensors should be ideally placed on bearing houses. This way you will get an info about a bearing it self and also about mechanical faults related to shaft speed. Placing the sensor on engine mounting makes sense only if you are looking for loose foot, loose anchoring bolt basically. See this video about sensor mounting: kzbin.info/www/bejne/h5-rnWSCmpeCjqM

@@AdashCompany thanks for your reply and for the additional video link. In our case we're more on checking the quality of the newly overhaul engine and it's alignment after installation during sea trial. Usually the engine and transmission were coupled to a shaft going to the propeller. Bearing problem is unlikely to happen since new parts were used. It's more of a workmanship check rather than predictive maintenance purposes. Usually our engine alignment was affected by the hull and vessel frame strength and the stress and strain it absorb while sailing especially on rough waters

[@AdashCompany]

​@@coltruiz7126 Keep in mind that bearings could have been installed incorectly. Misaligned machines are also trouble for bearings because then they are stressed by unwanted load from the shaft. Therefore don't overlook bearing monitoring... Anyway, please write to our sales / technical department. We will guide you to apporiate Adash dealer in your country who can help you to find suitable solution for you. Email: [e-mail]

Good information.

[@demohmand]

Another great informative video, great job team Adash!

[@mohammadalabsi5360]

Hi, thank u for ur good presentation, pls advise if we have a level problem for pump or foundation which causes a high vibration, what can we consider this ? Is it unbalance? Or what ? Thnx

[@AdashCompany]

It could be unbalance, looseness, resonance and other problems. It is really impossible to answer to your question. You would need to perform some vibration analysis on your machine.

[@tahirkamboh147]

We have reduced the unplanned downtime to Zero, by using Adash Vibrio M

[@toomuchdebt5669]

Not all problems vibrate.

[@prashantdhule4815]

For vibration severity: iso10816 which RMS velocity did u consider (overall RMS velocity or individual RMS velocity ?

[@AdashCompany]

Overall RMS velocity.

[@Basith-007]

Can anyone pls suggest me a college for vibration analysis.... The best college with excellent practical studies

[@AdashCompany]

Look for example on LinkedIn where you can find plenty of vibration diagnosticians and you can contact them.

[@imajit8970]

Thank you for great information

[@nukulkhadse5253]

In the calculation, 25Hz x 60 = 1500 RPM, how did you consider the value 60 into calculation?

[@AdashCompany]

1 Revolution per minute is equal to 1/60 Hertz. Hertz is the SI base unit of frequency defined as one cycle per second.

Hi, how much the training fee for Vibration analysis category 1

[@AdashCompany]

We are not a training company sir. We are manufacturer of vibration analysis tools and software.

[@mayank1up]

Thak you for this very useful information. Could you please elaborate what does high horizontal and vertical vibration (in mm/s) mean given that the relative vibration in axial direction is less.

[@AdashCompany]

That is quite complicated question. Horizontal and vertical vibrations usually gives us info about imbalance, mechanical looseness etc. Axial direction is important while looking for misalignment problems. Write us more about your troubles on [e-mail] and we will try to guide you.

Very informative, Thank you very much!!

I need to buy one, in Bangladesh where we can buy..?

[@nagarajnaga5969]

How do you find the lubrications issues from accelerations.

[@AdashCompany]

Bearing with lack of grease will of course vibrate more than greased bearing. Try to grease the bearing while measuring acceleration and see if the value decreases. If yes, then you solved your lubrication issues.

[@guillermocardozo8458]

Excelent explanation; this is the first time that I see something like this....Adash could you please send this information in pdf format?

[@AdashCompany]

Thanks for your comment. We are actually preparing our educational videos in PDF. We will place them on our website once available. Stay tuned :-)

[@AdashCompany]

​@Jack Lu You measure it with just one sensor. From accelerometer you get acceleration in g. Then the analyzer converts acceleration into velocity in mm/s by integration.

Great Video and very informative

[@egzonkastrati35]

Great information, well done!

[@MrT79shakeshake]

Good clear concise video.

[@MrAnthemboy]

Using a loose cable between DAQ/signal reader and the accelerometer like this will induce vibrations that will affect the accelerometer. This should definitely be avoided for accurate measurements

[@AdashCompany]

Yes, you are right. But the influence from cable vibrations is very low. We can overlook it in the field / route measurements and concentrate on this cable issue for laboratory measurements where we need really precise reading. There are another interferences in factories such as electromagnetic fields which also influences the measurement.
