Restrained spring
mounts are isolators that provide vibration isolation for mechanical systemsand equipment. These isolators are designed in a way to limit vertical and
lateral movement of the top support plate caused by equipment operation or wind
loading. The uniquely-engineered springs are designed to provide maximum
isolation to the mechanical equipments.
There are mainly
two types restrained spring mounts namely open restrained spring mounts &
closed restrained spring mounts.
·
The Open Restrained Spring mounting
is designed specifically for applications where transmission of low frequency
machinery vibration to a building structure must be reduced to avoid physical
damage or nuisance to the occupants. It is a low frequency mounting designed to
limit vertical movement on equipment such as cooling towers and chillers etc.
Applications located at roof level can be successfully mounted on ORS units as
any movement caused by high wind loads will be limited. Equipment which
contains large volumes of liquid will benefit from installation on ORS
mountings because during “draining down” upward movement is restricted thus
avoiding damage to pipe work and electrical connections.
·
Close
restrained spring mounts isolators provide vibration isolation for mechanical
equipment. These close housed isolators are-engineered springs that provide
very good isolation. Closed restrained spring mounts are a sturdy construction
with robust design that offers excellent performance.
Features
·
Spring Mounts provide the good deflection of up to nearly 2″ to
ensure excellent isolation.
·
Made of high quality metal springs & rubbers provide excellent
isolation
·
The spring serves to isolate
a broad range of disturbing vibration frequencies, while the rubber is a high
frequency or noise break
·
The vertical and lateral restraints consists rubber inserts to avoid
any metallic contact and ensure adequate radial clearance for isolation
efficiency.
Application of restrained mounts
The applications
include both indoor and outdoor mechanical equipment isolation with lateral
loads and minimal to no change in operating weight. Typically these equipments
may be used in cooling towers, base-mounted fans, chillers, air handling units
and much more.
