SELECTION OF MATERIALS AND FLUIDS FOR USE IN HYDRAULIC SYSTEMS AND THE RELATIONSHIP WITH LUBRICANTS

The paper considers various types of hydraulic fluid and their effect with materials of hydraulic system construction. Emphasis is given to mineral oils as they are the most widely used type of fluid; the factors influencing selection of oil type and viscosity grade are discussed. Oil type is largely influenced by water separation properties and the materials of wearing surfaces, mainly metals, and viscosity grade selection is primarily governed by the operating temperature range required coupled with minimum and maximum viscosity requirements of the system. Fire resistant hydraulic fluids with viscosities such that they can replace mineral hydraulic oils are considered and their limitations assessed. Fluids with special properties, such as ability to operate at higher temperatures than mineral oils, are summarized, and the application of high water content fluids, with their limited lubricating ability, is discussed.
