www.machinerylubrication.com | November - December 2021 | 31 ML ML ML Do modify your equipment and review your tools. Machine modification can be a daunting task, but it doesn't have to be. Look at your reliability goals for that piece of equipment. Look at the aspects that might prevent you from reaching those goals, i.e.: Does this machine need to breathe? Does it have clean and dry air to breathe? What do I need to do to make sure that it does have clean and dry air to breathe? Are there tight targets for cleanliness? Do I have a way of getting clean oil into the machine? Would something like hydraulic quick connects help prevent unwanted contaminants from entering my machine? Is this machine susceptible to water contamination? How is water/moisture getting into my machine? Am I using lip seals where I should be using labyrinth seals? Are there any early warning indicators, like bottom sediment and water bowls, or even moisture sensors, that can be installed? Don't buy every sensor on the planet and put it on your machine. Sensors, quick connects and desiccant breathers are great tools, but not every piece of equipment warrants the investment. A non-critical piece of equipment may be more efficient if left to die on its own versus using every piece of technology available to extend its life. ere is no magic bullet when it comes to setting cleanliness targets or reliability goals for your facility, but doing proper contamination control doesn't have to be some daunting task. e first task should be to figure out your reli - ability goals for any given piece of equipment. Once that is figured out, you need to determine what cleanliness target will help you reach those goals. Here www.machinerylubrication. com/Read/29526/oil-cleanliness-targets is a great calculator to help you out with cleanliness and dryness targets (remember, moisture is the second most damaging contaminant to your oil and machine). Great! Now that we know how clean and dry we need to get our oil, how often do we actually sample it to make sure we are hitting our targets? We made a calculator (Figure 1) for that too! Now, using these two calculators in tandem, along with your overall criti- cality, you should be able to easily determine what sensors or modifications should be performed to help you achieve your goals. If you are still having issues, or have ques- tions about criticality and how to calculate that, send us a message, we will be happy to talk you through it (we might even have some tools available for that, too).
