36 Fluid Power
Fluid Conditioning
The fluid conditioning group involves main-
taining and conditioning system fluid. This
requires removal of dirt and moisture from the
fluid and assuring proper operating temperature.
Specially designed components are available to
perform these tasks. However, basic systems often
maintain the fluid using other system components
that perform the task as a secondary function.
Filters are used to remove dirt and moisture from
systems, although a properly designed reservoir
can perform this task under certain conditions.
Maintaining the proper system operating tempera-
ture can require the use of a heat exchanger. How-
ever, this task is usually performed by dispensing
heat through the reservoir, system lines, and other
components.
Basic System Components
Fluid power systems are constructed of various
components that perform the specific system func-
tions. The number and appearance of components
required to perform these functions varies consid-
erably depending on the complexity and accuracy
of the work performed, the environment in which
the system operates, and the manufacturer of the
component. Understanding the operation of fluid
power systems requires an understanding of the
construction and operation of the components that
form the structural groups of the system. Refer to
Figures 2-3 and 2-4.
Power Unit
The appearance and structure of the power
unit in a fluid power system can vary considerably,
depending on the application of the system. In
basic systems, the power unit consists of a prime
mover, pump, reservoir or receiver, mechanical
coupler, and the fluid conductors required to make
the unit operational. Terminology and design vary
somewhat between pneumatic and hydraulic sys-
tems, but direct comparisons can be made between
the two systems. For example, in pneumatic sys-
tems, the power unit is generally referred to as the
compressor, Figure 2-5. On the other hand, in
hydraulic systems, the power unit is called a pump,
Figure 2-6.
