We are very excited to be both speaking at and sponsoring the IDCON Pulp and Paper Industry Reliability and Maintenance conference March 19 – 22, 2017 in Raleigh, NC. Save those dates! Their schedule is packed with high-impact presentations, technical sessions, workshops, and networking opportunities. The conference keeps its long tradition of fostering an environment where attendees share information and experiences and walk away with new, practical knowledge.
Our own presentation is a 2-hour workshop titled The Six Hydraulic Reliability Checks You Aren’t Making. Most industrial plants regularly change their filters and maintain the oil level in their reservoirs. Unfortunately, this is where hydraulic reliability ends at many facilities. When the system fails, there is little or no reference information available to be used in troubleshooting. Hydraulic components are often thought to be like light bulbs – they work great until they fail, then suddenly they are no good. Yes, it is possible for some components to fail without warning, but most wear is very gradual and easy to track.
Almost all components will display symptoms of wear throughout their useful life. Usually when most components wear they will leak. This is obvious if they are leaking onto the floor, but mostly they leak internally, which we call “bypassing”. This will result in a pressure drop across the component. Whenever a pressure drop occurs that does not result in useful mechanical work, heat is generated. Almost all hydraulic components have pressure drops across them, so some heat generation is normal, but unless we have some idea of what “normal” is, it can be hard to tell when the temperature gain is abnormal.
In this presentation, we will discuss what, in our experience, are the six hydraulic reliability checks that are usually not performed but should be. If you know what to look for, components that are about to fail can be replaced during the next scheduled outage BEFORE they cause an expensive outage! None of these checks are very time consuming and none require expensive diagnostic equipment. You probably already have everything you need to increase your hydraulic reliability and reduce your downtime. Just a few minutes a month can save hundreds of thousands of dollars in lost production.
