Pneumatics Word Exercise Answers
Pneumatic control is fast and clean which makes
it ideal for use in textile and food industries.
Air is Compressible which means it can be
squeezed into a smaller space. Air holds
moisture which causes Condensation (Dew droplets)
in the compressed air system. Because pneumatic
components often function with metal to metal
moving contact, Lubrication is required and is
introduced by the Service Unit which contains a
Filter, Regulator and Lubricator. High pressure
air is produced by Compressors. The flow of air
is measured as the Free Air Delivery (FAD) in m3
per hour.

Hydraulics Word Exercise Answers
Hydraulic control produces extremely large forces
which makes it ideal in pressing applications
such as car body panels or in lifting equipment
such as cranes. Oil and water is Incompressible,
therefore the fluid cannot be compressed. Fluid
generally needs Lubricating (for metal to metal
movement), Anti Oxidising (to stop oxidisation)
and Anti Foaming (to inhibit fluid foam)
properties which are produced using
Additives. Fluid flow is produced by hydraulic
Pumps. These pumps are usually positive
Displacement devices. The fluid flow is
transferred through Hoses that are Braided
(platted) for reinforcement, or steel Pipes, to
contain the very high pressures.
