Title: PdM Managers’ Workshop #4: Predictive Maintenance Program Implementation and Integration

Date: Friday, May 18, 2007

Time: 11:00 AM - 12:30 PM EDT

Please join Jack R. Nicholas Jr., CMRP for the 4th of a 10 part series of Predictive Maintenance (PdM) Program Management.

In the 4th Workshop Jack discusses:

* Predictive Maintenance Program Implementation
* Creating a Predictive Maintenance Program Implementation Plan
* Integrating the PdM program with your current Maintenance Program
* The role of CMMS in a PdM Program

There are several polls conducted throughout the Web Workshop that provide a real time snap shot of attendees PdM practices. Results will be discussed to highlight workshop lessons.

There is no fee to attend the Web Workshop

Space is limited. Reserve your Web Workshop seat now

RCM Training is Only the Beginning

Many RCM programs today fail within the first year because of one simple problem: The lack of guidance and real-world experience. Classroom training is only the beginning when it comes to starting an RCM program. Every experienced RCM professional will tell you that attending classroom training and trying to start a program on your own is a recipe for failure. The best practice in starting an internal RCM program is to find an experienced professional to guide your team through a few projects until your team is ready to be self-sustaining. This OJT, along with classroom training, is part of the foundation that will lead to long-term success of your RCM program.

Scan Your Bearing with the Scanning Module!

When scanning so many bearings that you cannot possibly make contact with them, use the airborne scanner. Always approaching the bearing at the same angle and using the same sensitivity. Scan the area first to listen for competing background sounds that may be in the ultrasonic range. Scan and set a baseline and set a decibel alarm level so that you can identify a deteriorated bearing and schedule a removal or replacement if needed.

Great application! Particularly for conveyor systems were bearings are not always accessible.

Garbage in…Garbage out.

Even the best laser system in the world is only as good as the craftsman that operates it. If you put inaccurate information into it, you will get inaccurate information out of it. Albert Einstein once said that the definition of insanity is to do the same thing over and over but expect different results. Be as accurate as your system requires when inputting required data. If measurement results are not repeating, determine why before making corrections. Remember, machinery corrections are calculated from the measurement results. If they don’t repeat, neither will the corrections and you will be making many unnecessary moves; you will be doing the same thing over and over but expecting different results, garbage in…garbage out.

A New Report by Allied Reliability!

The value of Reliability-Centered Maintenance is proven!

It is a logical, sensible approach that helps companies better understand their equipment and improve reliability.

Yet most companies are not getting the return on investment they expected.

They see RCM as too much trouble for too little reward. That’s why we published this report.

You’ll find out why your current RCM projects aren’t working, what needs to change and how to put RCM to work at YOUR company so it doesn’t become a Resource Consuming Monster.

There’s a reason many RCM projects fail to deliver results.

We want you to find out why and How to Avoid the 5 Biggest Mistakes that Lead to False Starts and Dead Ends in your RCM program.

Recently I was asked to find the source of a bad vibration on a production line.

I couldn’t access the measurement point because it was behind a guard so the machine had to be stopped and locked out before I could mount an accelerometer at the various locations. I used real time spectral monitoring to zero in on the source, which was located quickly. I identified the problem bearing to the mechanics and went on my way. I have done this type of job previously, but because the 2120 can’t store the spectral results from this reading, I decided to also capture the same data using the acquire spectra method.

When I got back to my office, I brought up the data and tried to analyze it.

The bearing I thought to be good now had the highest amplitude vibrations; the one I thought bad had very low amplitude.

I quickly tried to stop the work, but was too late. My first diagnosis proved to be correct and I returned to my office puzzled. What had happened?

After checking settings and thinking about it, the embarrassing answer was revealed!

When I was looking at the vibration in real time, I was seeing unaltered data. I had noticed there wasn’t really a one time peak, there were several occurring in a band.

When I captured the data for later analysis, I left the settings for route collection which included averaging the collected data 5 times. Since there was no repetitive peaks in spectral data for the bad bearing, they averaged close to zero. On the other hand, the good bearing had a normal signature and averaged out correctly.

I am now a more knowledgeable analyst that hopefully won’t be caught by this phenomena again.

Constant Level Oilers – Oiler Location

As the name implies, constant level oilers are designed to supply lubricant, as needed, to maintain a constant level within a bearing housing. Its function is to replenish lubricant lost by leakage through seals, vents and plugs in the bearing housing. If the lubricant level within the sump lowers below the control point, the seal at the control point is broken, allowing air to enter the reservoir, displacing the lubricant. The lubricant from the reservoir will flow into the surge chamber until the seal is re-established constantly maintaining the lubricant at the optimum level. However, problems can arise when reverse flow to the oiler occurs.

Bearings create currents and flows in the housing as the shaft rotates. The location of a constant level oiler relative to shaft rotation can effect how the oiler dispenses - especially in higher speed applications.

On start-up, as the shaft rotates, it will pull the lubricant to one side of the bearing housing. The oiler should be mounted so that the lubricant is pushed towards the oiler. If it is mounted on the incorrect side, and the lubricant is pulled from the oiler, the oil level momentarily drops below the control point, causing the oiler to feed. Over the course of several start-ups, the lubricant level within the bearing housing will increase above the optimum level.

In high-level operating conditions, the bearings will require additional energy to go through the high-level lubricant. This energy converts to heat in the lubricant, causing it to lose its viscosity. In addition, “churning” of the lubricant will occur, accelerating the oxidation rate as a result of the excessive air and heat.

The most common fix for this condition is to mount the oiler on the opposite side or on the bottom of the housing to eliminate mis-feeding due to currents created by the bearings.
