im a technical inspector in sugar cane factories. in our factory i have a routine inspection for rotary equipment with a termometer & vibropen monthly.and list my out of range dataes.then i check those equipment with a VMI Vibro-Analyser and analyse The dataes with Spectro-Pro software.
Now I Whant to know What is your opinion about it?lead me in my way.

That is a good start, go ahead build-up expertise, credibility, network on this forum, and probably 3 years from now, you will have other (maybe better) equipment and techniques.

Vahid,

I have not used Spectra-Pro software, but it does not appear to include demodulated spectrum, overall level and frequency band trending/alarms, and spectrum/waveform comparisions (two or more traces on same plot), and fault frequency markers. These tools can be very helpful for maintaining a routine monitoring program. There are several data collector and software products that include these features.

Before you consider changing or updating your tools, be sure you are getting the most effective results from the tools that you have. In many cases a more training and improving procedures should proceed a tool upgrade. Can you answer these questions?

Does the condition monitoring detect most of the developing faults with adequate warning time?

Does the analysis correctly identify the type of fault and severity?

Do you make (report) practical recommendations for corrective actions in a reasonable time?

Do other plant personnel believe in your work (credibility)?

Has your condition monitoring efforts proven to be cost effective (labor and expense Vs savings in repairs and downtime)?

Are you taking Proactive steps to reduce failures (precision alignment, precision balancing, structural modifications, lubrication, detailed purchase and repair specifications)?

I commend you on taking the initiative for self evaluation.

Current version of SpectraPro do have bearing database and trending. At least Easy-Viber do have envelop processing so the work to be done is to collect data at good places, look at the levels and spectra and trending, and now the tricky: judge what must be done and what is requiring some work to be done right now and what can wait. Is it the hi level machine that been like that forever, is it that 500% increase from nothing to something? On a new site one way to have a reference is to compare to ISO or some other favoured set of standards, then look at those machines that violate the standard limits, then look at those that have a dramatic trend increase, and those where the data look funny and where the machine behaved funny during data collection etc. and on and on. You never stop learning. I will now go and have a look at a machine that makes those funny holes around postage stamps. Things people invent never stop to amaze me. Have fun and keep collecting and looking at the data. Olov

Vahid:

Consider your needs before selecting processes or equipment/instrumentation. It may even be that you have the necessary capabilities for your purposes already.

I recommend you review the attached, which can be applied to considerations for any type of system, prior to moving forward with suggestions.

Vahid,
You have one of the most challenging enviroments to work within. A sugar mill can offer many challenges. The ones that I know of in Australia only run about six months of the year. For the rest of the time the machines sit idle. This in it self provides some major obstacles.
As mentioned by some of the other replys make sure you are doing it for the right reason.
Things to keep your eye on as you go about your work.
1. These machines often fail due to lubrication issues, They work genrally through the hotter times of the year and sit still for the colder times. Seal leaks, contamination due to condensation/water etc are big things to be aware of.
2. Special attention to balance and misalignment conditions on your machines will help improve the reliabilty of the equipment.
3. Educate as many people as possible to why your work is so important. It is a proven fact that these sugar mills have very small budgets and unplanned stoppages affect everyone. So it is Imperitive that all no the impact of a good Condition Monitoring program.

If I was in your position I would be trying to get to as much training as possible in the field of vibration, ultrasonic leak detection,thermography & oil analysis. I would also keep reading as much on this forum as you can, there are some very interesting topics with very practical solutions.

Do not be afraid of out sourcing some of your testing, there are many consulting companys around the world that can help you with this type of work.

Good luck.
