Ultrasound World VI Program Abstracts

Presentation: Monitoring of Variable Speed Bearings Using Structure Borne Ultrasound
Presenter: Dr James Neale, Senior Research Fellow, Energy Research Group, University of Waikato, Hamilton, New Zealand

Abstract: The condition monitoring of rotating bearings is a well know application of structure borne ultrasound, however this is traditionally been limited primarily to fixed speed applications. With increasing focus on plant automation and energy efficiency many traditional fixed speed motor driven applications are being fitted with variable speed drives, resulting in variable machine loads. Traditional instantaneous condition monitoring techniques, such as structure borne ultrasound, rely on a fixed baseline reference frame to determine any abnormality for further investigation. Under variable load situations it is important to differentiate between a change in the load condition and the presence of a condition abnormality.

This presentation will demonstrate the successful implementation of a structure borne ultrasound condition monitoring programme for variable speed applications in the New Zealand Dairy Industry. Initially basic equipment was isolated and tested under laboratory conditions to determine the correct monitoring methodology, followed by in-plant testing of live production equipment. The critical system parameters required to successfully monitor variable speed bearings will be discussed, including the characterisation of the required speed window, application load and recommended alarm levels. The primary benefits of this programme are the rapid testing of more equipment than would otherwise be possible, thereby increasing the level of plant coverage for the same maintenance budget spend. 

WORKSHOP
Energy Efficiency Workshop: How to take your Energy Efficiency Program to the next level.
Presenter: Dr James Neale, Senior Research Fellow, Energy Research Group, University of Waikato, Hamilton, New Zealand

Abstract: Energy Efficiency, "Green", Sustainability, and Greenhouse Gas Emission - the clichés could go on - many of these terms have become overused and their true meaning is often lost on most people. The debate will rage on but at some point the discussion must result in actions that bring about a real and significant step change to how we do business. 

Most businesses have focused on the simple things and have had a program that has "turned off the lights", but this is not enough. How can we take the success of these initiatives and step up to the next level? A holistic approach to the energy efficiency and reliability of processes, systems and equipment can yield a far greater benefit in the long term.

This workshop will provide you with real examples of not just how to implement energy efficient programmes but also how to build the robust business case for them in today's difficult economic times. Using real case studies as examples topics covered will include the impact on specific energy efficiency of plant reliability, process quality and process efficiency. The importance of holistic system wide analysis and auditing will be demonstrated along with how you can tap these resources for your own plant.

The use of ultrasound will also be specifically covered in relation to higher level applications, including compressed gas systems, motor driven equipment and process heat systems.
