ABSTRACT
The objective of this chapter is to give the reader some practical understanding of the hardware needed to connect the various components (pumps, actuators, valves, accumulators, filters, oil coolers) in a circuit. Just as the two key parameters in fluid power are
P
(pressure) and
Q
(flow), the two key issues in the design of the lines between components are sizing for the recommended maximum fluid velocity (related to
Q
) and selection of the pressure rating (
P
). There are two pressure ratings of interest to the designer: working pressure
and burst pressure. Conductors are chosen that have a working pressure rating greater than the expected maximum pressure in the system. (Typically, this maximum pressure is the relief valve setting.) Burst pressure is the pressure at which the conductor is expected to rupture.
