Web Based Vibration Analysis Programs

A preventive maintenance program adopted at the mill has clearly improved the reliability of 16 raft-mounted mixers that help stimulate the biological treatment process removing organic solids from process effluent. The proactive approach to maintaining the mixers, utilizing factory-authorized service, has corrected problems with the previously rebuilt units and delivered significant savings to the mill.

Vibration analysis, properly done, allows the user to evaluate the condition of equipment and avoid failures. Maintenance personnel can minimize unplanned downtime by scheduling needed repairs during normal maintenance shutdowns. How can you interpret — at a glance — the comprehensive spectrum information available? In layman's terms, here is how to interpret the vibration signature of rotating equipment. You can learn to recognize misalignment, a defective bearing, bent or loose parts — and tell them apart.

Equipment inspections is key to keeping your production running but many plants don't tap into all the resources available. IDCON Reliability and Maintenance Management Consultant, Michael Lippig has a simple decision chart that will help you decide what tasks can be done by what roles.

The potential-to-functional failure interval (P-F interval) is one of the most important concepts when it comes to performing Reliability-Centered Maintenance (RCM). Remarkably, the P-F interval is also one of the most misunderstood RCM concepts. The failure mode analysis becomes even more complicated when you are dealing with several P-F intervals for one failure mode. This paper will help clarify the P-F interval and the decision-making process when dealing with multiple P-F intervals.

The next step that we talked about was, "How did the component fail…the grid coupling?" This is something that a lot of times, once we start doing this, for a grid coupling, if we set up a PM for this you can probably step straight to what kind of inspections would you do and you guys could tell me in three minutes and they’re probably pretty much right on. But I’m using something simple because I didn’t know who’s going to be in the class and what kind of technical skills you guys have. But using something simple and showing you the steps of how we break this down.  I think if we say how would you inspect a coupling that’s going on the run or doing what kind inspections do we need to do and shut down. I think you guys can tell me that. I’ll show you steps anyways so you can see the thinking process using something fairly simple.

For over 20 years, users of oil analysis have used the ISO cleanliness code to help determine solid contamination levels in both new and used oils. The current ISO standard for reporting cleanliness is ISO4406:99. Using this standard, analysts and end users alike have managed to establish cleanliness goals and develop key performance indicators (KPIs) with the expectation to allow for preemptive action to avoid early machine damage. While this has produced some success, relying specifically on the ISO cleanliness code as it is currently reported has its limitations.
