These functions require that fluid be circulated through the system to remove excess heat, flush dirt from internal areas, and lubricate bearing surfaces while moving actuators to do the work for which the system was designed. These functions are facilitated by hardware such as the reservoir and fluid conductors. The reservoir acts as a storehouse for fluid while aiding in system cleaning and cooling. Conductors and associated connectors allow the movement of fluid between system components to transmit energy and also aid with cooling and cleaning. This chapter discusses each of these components and a number of design variations used by system component manufacturers. After completing this chapter, you will be able to: „ Describe the function of the hydraulic system reservoir and identify the primary design features involved in its construction. „ Explain the factors that must be considered when establishing the size of a reservoir for use in a system. „ Describe the factors that are basic to the design and structure of fl uid conductors used in hydraulic systems. „ Compare and contrast the various types of pipe, tubing, and hose used in hydraulic systems and explain the ratings for each conductor. „ Identify and explain the factors that must be considered when selecting a conductor for use in a hydraulic system. „ Explain the information typically found on data sheets provided by the manufacturers of hydraulic system pipe, tubing, and hose.
