Vibration and pulsation can be produced in an
air or gas cleaning installation by turbulence generated in
poorly designed ducts, transitions, dampers, and fan inlets
and by improperly installed or balanced fans and motors.
Excessive vibration or pulsation can result in eventual
mechanical damage to air filter system components. Weld cracks in ducts,
housings, and component mounting frames can be produced by
even low-level local vibration if sustained, and vibrations
or pulsations that produce no apparent short-term effects may
cause serious damage over longer periods.
Vibration produces noise that can range from
the unpleasant to the intolerable. Important factors in the
prevention of excessive vibration and noise include planning
at the initial building layout stage and space allocation to
ensure that adequate space is provided for good aerodynamic
design of ductwork and fan connections. Spatial conflicts
with the process and with piping, electrical, and
architectural requirements should be resolved during early
design to avoid the compromises so often made during
construction that frequently lead to poor duct layout and
resulting noise and vibration. Ducts should be sized to avoid
excessive velocities, while maintaining the transport
velocities necessary to prevent the settling out of
particulate matter during operation. Fan vibration can be
minimized through the use of vibration isolators and inertial
mountings.
