Tuesday, 5/20, 3:00-4:00pm. Gilpatrick Room. The National Fluid Power Association recommended practice for viscosity selection criteria in hydraulic equipment was adopted in 2002. This standard was the first specification to define a process for selecting the appropriate hydraulic fluid viscosity based on OEM minimum and maximum viscosity requirements and the temperature operating window of the hydraulic fluid. Recent studies have established that hydraulic system efficiency is dependent on the hydraulic fluid viscosity after shear. It was further shown that the amount of fuel consumption in mobile hydraulic systems is reduced by using a high viscosity index (VI) shear stable hydraulic fluid. Energy savings of greater than 10% were demonstrated. Studies also have shown that productivity, in terms of excavation rate, improved when the proper hydraulic fluid is used. This paper will address the inclusion of shear stability and energy efficiency criteria into a revised NFPA recommended practice for hydraulic fluid viscosity selection.

We explore the use of both hose and tube in fluid transfer applications, as well as some ideas and criteria that have proven to be important contributors to the successful design of hose and tube fluid conductors. We conclude with some of the unique challenges that are shared in the fluid power industry. Sponsor: R.B. Royal Inc. Speaker: Mark Robinson.

A wide variety of applications, pump failure analysis and corrective measures will be discussed. Tell-tale signs of early pump failure, pump cavitation, and pump aeration will also be covered. The session will end with symptoms of internal leakage and its effects on pump efficiency and operations. Sponsor: Attica Hydraulic Exchange. Speaker: P.K. Guha.
Wednesday, 5/21. 8:00-9:00 am, Executive A/B Room. Pound for pound, seals probably bring more to the table than any other component in a fluid power system. They must fit tight enough to keep high-pressure fluids from leaking; yet not be so tight that they wear prematurely. It's no wonder then, that there are so many different seal materials, shapes, configurations, and mating surfaces.

Tuesday, 5/20, 10:15-11:15am. Executive C/D Room. When was the last time you took a close look at the materials that are being used in your hydraulic manifolds, pumps, cylinders and valves? Did you realize that by switching materials you could cut the cost of making those components in half? Learn how continuous cast ductile iron has all of the strength properties of carbon steel but it can be machined at speeds that are as much as 2-3 times faster. Increased machining speed equates to less time and money to produce the part.
