Description:
Kinetics Model FLSS Seismic Control
Restrained Spring Vibration Isolators consist of free-standing, large diameter,
laterally stable steel springs assembled into welded steel housing assemblies
fabricated to limit vertical movement of the isolated equipment if equipment
loads are reduced or if the equipment is subjected to lare external forces
such as a seismic events. The housings also provide a constant free and
operating height to facilitate installation. Spring elements are complete with
internal noise isolation pads and have an adjusting and leveling bolt as a part
of the top load plate assembly. Holes are provided in all isolators for bolting
to the structure and to the supported equipment. To assure stability, the
springs have a lateral spring stiffness greater than 1.2 times the rated
vertical stiffness and are designed to provide a minimum of 50% overload
capacity. FLSS isolators are available with deflections to 4" (100 mm) and
with load capacities to 23,200 lbs. (10440 kg) as standard products. Custom
isolators with higher deflection and greater load capabilities are also
available. Kinetics Model FLSS Spring Isolators are recommended for the
isolation of vibration produced by equipment carrying a large fluid load which
may be drained, such as boilers and chillers, and for the isolation of cooling
towers, air-cooled condensers, etc., where motion due to wind loads must be
minimized.
Application
Kinetics Model FLSS Seismic Control
Restrained Spring Isolators are recommended as a noise and vibration isolator
for mechanical equipment located near critically quiet areas when the equipment
to be isolated has significant changes of weight during maintenance operations
and for equipment subjected to seismic events, external forces, or high wind
loads.
Model FLSS Isolators are typically used to reduce the transmission of noise and vibration into supporting structures from equipment carrying a large fluid load that may be drained, such as boilers and chillers, and cooling towers which also require hold-down for seismic and wind loads. Operating static deflections are available to 4" (100 mm) to compensate for long span flexible floor structures and to maintain a high degree of noise and vibration isolation.
