Brg Temp Monitoring/ Protection w/o Rack

Shurafa ·
For critical equipment with journal bearings, it is typical to have online racks to monitor and protect (trip) the machine if bearing temperature exceeds the set point. I'd like to hear from people working in O&G, chemicals, petrochemicals and power if you find it really necessary to have the protection though the rack vs through DCS/ESD. In most temperature problems I encountered (with all common machines: motors, turbine, gears, pumps and compressors), the real faults develop at rates...

Over the past few years, many SME were established focusing on condition monitoring technologies and taking advantages of the recent developments related to smart devices and internet. Many cute portable tools, add-on gadgets, phone applications, internet based systems etc have been introduced and they gradually mature as alternatives to the classic pricy products/services. That is good for the industry and may/may not be that good for the large player. A few major acquisitions were made...

Re: Condition monitoring integrated software

Shurafa ·
It would be much easier to select a new program that can handle different technologies than to find one that can talk to existing systems from different vendors. I do not have a specific recommendation for a company or model but I suggest to consider the reliability and effectiveness of running different systems over the convenience to have all the inputs in the single depository. In many cases, at least in my environment, one technology will be a main tool for the condition monitoring and...

Re: What is the Best Parameter to Monitor the Slow Speed vibration ,I have 43 RPM Calciner Support Roller brgs

Ramos_ ·
Collect time waveform set to 5-8 revolution. Sampling rate should be fast enough to capture transient event, set high fmax. For 43 rpm that means you need to set twf collection time to ~12sec for 8 rotation of the shaft. This is good enough to see event on the bearing for 8 revolution. If your software is capable to overlaid plot then that that help to visualize any changes. Trigger during data collection of this twf is also a good consideration so all twf collected starts at trigger event.

Don't expect too much of vibration analysis on slow equipement. To see a defect is not hard but to know the level of degradation and to estimate how long it will last is quite difficult. Keep the expectations of your boss/client low until you get a solid history on this particular bearing.

Early detection of equipment problems in my plant means that we can shedule parts, manpower, and take down our plant in a controlled manner which saves huge sums of money. When an autoclave goes down in an emergency they are a nightmare to get started back up and start up isnt even an option within 24 hrs of said emergency outtage. When your plant loses 100K an hour....well.... you do the math. We catch one critical peice of machinery a month and our equipment and wages are more than paid...

With the HVA sheme, it is easier to understand direction/orientation of the plot. With RAT scheme, I always knew which transducer I was going to use Demodulation for (T). Other than that, it really depends on your preference; so I'm not sure there is a right or wrong answer. Always keep good records of exactly where you mounted and how you oriented the pad (assuming that's what you have) so that anyone can properly re-mount and orient it properly.

Re: Will Giant Corporations Acquire More Vibration Startups? Why?

I have an opinion on this one. I think things are definitely moving towards online wireless senors and remote cloud based monitoring for balance of plant equipment. This will require automated diagnostics however and IMHO (In my humble opinion) most of the top selling vibration software programs use archaic alarm systems, do not have diagnostics, have not updated their technology in 30+ years (when it comes to alarms and diagnostics) and are simply not up to the task. I bet most of them do...

I have not used the product but I believe they are only taking RMS overall values and Ultrasound readings. They have very good marketing but you might notice there are no detailed product specifications on their website (that I could find)...

My interpretation is that Augury system makes a digital recording and then spectrum/waveform analysis and diagnostics are made at a remote location. I did not see any grey hair people in the company photos, so perhaps there is a lot of energy and not so much experience. I guess time will tell of capabilities and company survival. Walt

They are advertising for level 3 Vib analysts on the site( and require experience working on at least 3 of the main players Va systems), so I presume they are trying to add some clout/gravitas to what they are doing. Though why they have gone for rms is puzzling, then again they are aiming at Hvac and ahu guys.

A while ago, one did not see too many using machinery protection systems for this. Machinery control systems often do this. Your DCS can do this. If the temperature does increase suddenly, which it can, often there is substantial trouble with a shutdown needed.

Bill, As you may guess, the driver for this is to extend the range of the monitored equipment from the highest critical to a lower level but without spending the same large amount of money. So for instance, assume a plant operates a fleet of medium size water pumps which are (according to the plant standards) not mandatory to protect online. However, real maintenance and reliability demonstrate the value of online monitoring even if the alarms are received 5 minutes late (compared to...
