Keeping your operation up and running consistently is not a matter of fixing problems as they occur. Rather, it is identifying those problems prior to the time that they become a large issue that is really going to make a difference in reducing any downtime that you may experience. This is achieved through predictive and preventative maintenance services, part of which is a roll roundness profile analysis. In this article, we will identify what this analysis can achieve and discuss how often you should have it done. We will also look into other predictive maintenance services that can help with the operation of your facility as well.
Press rolls are under an extreme amount of pressure and any type of irregularity that exists is going to reduce the quality of the end product. Ensuring that your press rolls are round is one of the best ways that you can ensure consistent quality. Having a roll roundness profile analysis included in your predictive maintenance program can help to reduce any irregularities that may exist in your products.
The analysis is done by measuring the relative motion that takes place between the press rolls. Doing so can help to detect any irregularities that may exist, however, small they may be. Keep in mind that any small issues with irregularities today could quickly become larger issues tomorrow. In addition, since one part of the line is ultimately going to affect other parts of the line, you would want to ensure that there were not any irregularities at any time.
As far as how often a roll roundness profile analysis should be done, this really depends on your particular circumstances. Of course, it should always be done at startup and any time that you move or adjust the machinery, but it should also be done as required, according to the needs of your facility.
Along with a roll profile analysis, you can also include other tests in your preventative and predictive maintenance program. Here are a few additional services that you may want to consider.
Vibration Analysis – This type of analysis can detect issues that may be occurring within the machine early so that repairs can take place before the problem requires extensive repairs. In many cases, it may help to limit a problem with machine failure.
Infrared Thermography – Thermal imaging equipment can be used to detect the temperature of the equipment without coming in contact with it. In most cases, we will be looking for hotspots but there may be instances in which locating cooler areas can identify a problem before it becomes a bigger issue.
Oil Sample Testing – Monitoring the oil that is used within the equipment can often assist in anticipating problems, recognizing engine wear and determining if a repair is necessary before it becomes a catastrophic issue.
These are just a few of the additional options that may be beneficial if they are included in your predictive maintenance program. By using them, it can help to protect your investment and ensure that costly repairs are kept to a minimum.
