Ultrasound World IV (2008)

Ultrasound World IV Program Abstracts
The Ultrasound World IV program was full of exciting presentations packed with useful information. Here is a selected sampling of Presentations that were offered throughout the conference. 
 

Abstract: If used properly, ultrasound instruments can provide valuable information to plants in determining grease volumes for bearings and grease components. In an actual plant application the portable instrument provided the information to calculate the exact volume of grease to maintain a film for maximum bearing life. With this tool, as with all predictive tools, understanding how to effectively use them maximizes the cost benefitselection.

What is the most effective method for applying grease to a bearing? Most bearings generally need a constant film of lubricant in the range of 2-10 microns. The film of lubricant prevents the rotating elements from making metal-to-metal contact.  This presentation will discuss how our plant moved from scheduled lubrication (preventive scheduling) to condition-based lubrication using a specialized ultrasonic grease level instrument.  The method and results will be explained in detail.

Abstract: To answer the question "why are we still having lubrication related failures?" maintenance and reliability professionals often times find themselves digging through RCFA' s, the CMMS, and other documentation in search of a predominant causal factor. Some of the most often overlooked modes of failure are incorrect lubricant applied, insufficient lubrication, or over lubrication. The fact is the very detailed nature of an effective and successful lubrication program necessitates the utilization of a detail oriented, highly skilled, conscientious resource. As important is the implementation of a color coding system that insures proper lubricant selection.

But what about the insufficient or over lubrication issue?

In the hands of a trained, conscientious craftsman an ultrasonic listening device is a valuable resource that enables the user to insure the " right" amount of lubricant is used when servicing the asset. Simply by listening to the assets ultrasonic frequencies as interpreted by the ultrasonic listening device, the user can take a proactive approach to eliminating the root causes of over or under lubrication in rotating assets, while also identifying defects in the early stages of failure, thereby allowing the maintenance department to plan and schedule the appropriate defect elimination strategy.

This presentation will provide details about the use of common sense practices for implementation of a successful lubrication program.
