Analysis of hydraulic fluids, if done properly, can suggest maintenance procedures to improve hydraulic equipment reliability and extend system life. Significant cost savings can result. Where to take a sample There are two types of fluid sampling: static and dynamic. Static sampling involves extracting a fluid sample from a reservoir or a dead zone, where there is slight fluid movement. Little useful information is gained from static sampling because: • contaminant concentration gradients exist within static fluids. Water and particles tend to segregate and settle due to gravity. Therefore, samples taken from different sections within the static container yield completely different results, and • particles from reservoirs may describe system histories, but provide little information on what is happening now. Large reservoir volumes dampen out dynamic changes and conditions within the system.

Water in a hydraulic system constitutes a serious form of oil contamination. However, water contamination is rarely recognized as such, hardly understood, and, until recently, considered difficult to combat. The damage caused by water is usually attributed to other causes. Water often interacts with other types of contamination. It causes both degradation of the hydraulic oil and damage to the hydraulic components, which reinforce each other. In the past, the filtration of hydraulic oil was solely aimed at removing solid particles. The hydraulic industry has therefore made great progress over the last twenty years in applying and maintaining well-designed filtration of solid particles from hydraulic oil. However, the recent introduction of water-removing filters seems destined to shift the focus in the management of hydraulic oil contamination.

This paper discusses the problems associated with hydraulic fluid contamination in aircraft as well as the benefits to be achieved by fluid conditioning. Also discussed is fluid conditioning prior art and the proprietary designed preferred by Diagnetics. Finally, it is propose that fluid conditioning be used to insure test stand fluid health and cleanliness. This application, provided with routine oil analysis, might lead to much broader uses.

With manufacturers expecting over 1,000,000 product-liability suits annually by 1980, more and more emphasis must be placed on safety and failure prevention. Companies with a poor track record, and which deal with ‘”accident prone” equipment, have little choice if they plan to survive the onslaught of an aroused, safety-minded and suit-conscious public. This paper is the first of a two-part series dealing with safety considerations in fluid-power systems. In this part, a panorama view is presented· of the factors that should motivate the fluidpower industry to take immediate action to ensure that safety is designed into their products. Time is of the essence, and we must get our house in order now.

Product safety must be our business-not a sideline or an activity that our trade 01: technical association performs for us. As emphasized in Part 1 of this report, with the everchanging public attitudes, climate of the courts, standards being approved, and edicts by the government; this is no time to “stick our heads in the sand.” This paper is oriented toward the fluid-power industry and not only offers a safe product design approach but also attempts to put fluid power-type failures into proper perspective. Specific solutions to critical and inherent problems are presented to taunt and provoke the reader in finding practical answers to save our industry.

Marketing should play a major role in the design of new fluid power products. The wants, needs and problems of the consumer are many times ignored as important inputs to product design. Without the use of marketing information, products can develop that are not competitive in the marketplace by failing to meet the needs of consumers.

This paper describes the role of marketing in product design and emphasizes the interaction and exchange of ideas between engineering, industrial design, and marketing. Such a market oxiented approach produces products that practically sell themselves. Applying this approach to the design of fluid-power products should have a tremendous, positive effect on the industry as a whole.
