I would like some unbiased opinions. If you were handed a vibration report the like the one I’m trying to post what would be your assessment based on the limited information. Would anything warrant concern?
Note: The measurements represent individual measurement points. The samples were collected by a walk around operator using an overall vibration level meter set to in/sec (Peak). One other thing of interest is that the levels are not trending upward over time and as a result the levels listed are said to be operating baselines. It is assumed that everything is in good working order and the mechanical integrity of the equipment is not in danger of being compromised.

Dear Waylon,

So much for the numbers...

What is the application, etc.
It all depends where they were taken also.
I must say that I could not make head or tail of this array of numbers.

Sooooo much more info is missing.

Marko Leo

Hello Waylon

First I would be suspect about the fact that these measurements follow such a close numerical order.Also that so many readings are exactly the same, possible yes.But something does not look right!!Like 13 measurements at .13 I have a hard time doing that on the same measurement point from collection to collection.But to have this many is a bit far fetched as far as I am concerned.Defective data collector?Are you able to manualy enter data on this collector?Also you say the trend is not increasing.Are they decreasing?Can machines live at 3.25 in/sec?Have you the ability to follow the data collector person to see if it is his or her technique?No matter which way you look at it it does not seem like real numbers.Got me. Hope someone has a real idea as to this phenom cause I would like to know.By the way what is your opinion on this Waylon.

Sorry for the confusion. Each number represented a measurement point on a machine such as motor fan end. The reason so many numbers are the same is due to the placement of the decimal point on the machine. Apparently the mechanics like fewer digits because it’s easier for them to write down on a log sheet. As a result the numbers get rounded up or down. That’s why so many numbers are the same. I also sorted the numbers descending in amplitude. Here is a short example of a log sheet. I promise the numbers are real.

Vibration Coupling End = MCE
Vibration Fan End = MFE

Equip. # MCE MFE
Motor 1 0.36 0.3
Motor 2 0.32 0.39
Motor 3 0.64 0.29
Motor 4 0.12 0.11
Motor 5 0.11 0.13
Motor 6 0.18 0.14
Motor 7 0.18 0.13
Motor 8 0.23 0.29
Motor 9 0.39 0.36
Motor 10 0.18 0.16
Motor 11 0.15 0.18
Motor 12 0.21 0.32
Motor 13 0.13 0.15
Motor 14 0.8 0.79
Motor 15 0.4 0.39
Motor 16 0.39 0.69
Motor 17 0.33 0.4
Motor 18 3.25 1.68
Motor 19 0.78 0.64
Motor 20 0.16 0.25
Motor 21 0.12 0.14
Motor 22 0.08 0.07
Motor 23 0.05 0.06
Motor 24 0.4 0.56
Motor 25 0.47 0.53
Motor 26 0.4 0.34

What kind of equipment? How long have these levels been trended?

Yep.. I would want to see the spectrum and waveform data, especially on:

Motor 18
Motor 19
Motor 14
Motor 15
Motor 3

but I just glanced thru your list.

How are you doing ? Hope all is well at your new job.

Mike

I would prioritize: adress the worst first.
1 & above
0.75 and above
0.50 and above
0.3 and above
Need a good RCA

Assuming you're limited else you would have posted more. You have OA levels from vibration. Operating parameters within limits? Heat or temps from an IR meter? Oil analyses? Visuals of cracked bases, coupling grindings, bldgs shaking???????????????????????????/ you know the rest!

Request alignment records: always good for a laugh. Get histories and frequencies of rebuild, etc... Find the most POed guy in maintenance and ask, 'what do you think'. He-he.

Hey Mike it's been a while. The jobs great everything fun as usual with lots of new battles to fight. Thanks for asking. 
Hey Sam how have you been? Yes I am limited by what I say. I try not to point fingers. I just wanted to see what first response others would have to the numbers. By the way, I think I need some new key-stock. Mine’s probably bent.

“Well, some people create their own opportunities; others go where opportunities are the greatest; others fail to recognize opportunity when they are face to face with it.” (Walter P. Chrysler)

Waylon,

Looks like a hell of a lot of measurement points have high vibrations! So get busy and figure out what is wrong and how to fix it. That's what you were asked to do, isn't it?

Walt
