As compared
to rubber mounts, spring mountings have greater static deflection resulting in better
isolation efficiency. This makes them more suitable for critical applications, especially
for mechanical and industrial equipment which have low disturbing frequencies.
Spring mounts come in a wide range of deflections offering maximum load, so
that the level of isolation can be accurately selected for each application.
Closed Spring Mount
Closed
spring mounts are used beneath mechanical equipment, either alone or in conjunction
with inertia bases. They are installed with the purpose of minimizing the
transmission of noise and vibration to the building structure and providing a
rigid lateral support. They are suitable for indoor and outdoor mechanical
equipment isolation with lateral loads and minimal to no change in operating
weight. They are mainly used in mechanical equipments such as fans, pumps, air
handling units, booster sets, etc. These instruments offer an economic solution
to any kind of vibration problems in industrial or mechanical equipment.
Open Spring Mount
Open spring mounts are
a simple free-floating top caps and cup bases that provide attachment
points and leveling adjustment. These mounts are used in the mechanical
equipment, alone or in conjunction with inertia bases, to reduce the
transmission of noise and vibration to the building structure. These open
spring mounts are typically used to isolating
mechanical equipment that produces lower frequency vibrations. They ensure the highest level of
stability for un-housed mounts. Built-in leveling arrangement and neoprene
acoustic friction pad provided, it is Suitable for any installation where
mounted equipment are not subject to significant horizontal thrust or wind
pressure. These instruments are quick and easy to install. Open spring mounts
are used in applications like fans, pumps, and HVAC units.
Restrained Spring Mount
Restrained Spring
Mounts are supplied with a housing that restricts vibration and noise. These
equipments are useful especially when subjected to any wind loading or changes
in weight during maintenance. These isolators include welded housings designed
to limit vertical and lateral movement of the support. Restrained Spring Mountscome in a wide variety of ratings and spring deflections. They are encased in housing
with adjustable limit stops. When set correctly, the springs will provide
appropriate isolation. But in case the
equipment changes weight significantly due to any fluid drain during
maintenance or moves due to wind load, prevent the spring from moving
excessively. Restrained spring mounts are applications that include indoor and
outdoor mechanical equipment isolation, typical equipment may include cooling
towers, base-mounted fans, and air handlers.
