TYPES OF DIAGRAMS
There are many types of diagrams. Those that
are most pertinent to fluid power systems are
discussed in this text.
Pictorial Diagrams
Pictorial diagrams (fig. 12-1) show the
general location and actual appearance of each
component, all interconnecting piping, and the
general piping arrangement. This type of diagram
is sometimes referred to as an installation
diagram. Diagrams of this type are invaluable to
maintenance personnel in identifying and locating
components of a system.
Cutaway Diagrams
Cutaway diagrams (fig. 12-2) show the internal
working parts of all fluid power components in
a system. This includes controls and actuating
mechanisms and all interconnecting piping.
Cutaway diagrams do not normally use symbols.
