PRODUCT DRAWING
DESCRIPTION
Many other parameters must be considered.
Stability The distance between 2 air bellows must be at least twice
the height difference between the centre of gravity and the
mounting plane of the air bellows.
Lateral vibrations The air bellows have a low lateral rate, it is
recommended to provide bumpers to limit the amplitude of the
lateral vibrations.
Startup - shutdown During startup and shutdown of the vibration
sources, the loads supported by the air bellows will be important.
In order to avoid the damage of the air bellows, we recommend to
use stops which limit the height range (for example ± 10 mm from
mounting height).
Auxiliary tank The addition of a tank gives an increased volume,
which reduces the air bellows natural frequency and improves the
isolation. In order to be effective, the tank must be placed as
close as possible to the air bellows and connected with piping
allowing an important flow.
PRECAUTIONS IN USE -
Airsprings must not be pressurised unless they are restricted by an
outside frame or by a suitable load. - Strokes must be limited by
the direct use of bump stops or external stops.
- When stacking airsprings, special care must be taken to ensure
the airsprings are guided and fixed.
- An Airspring is a single acting air actuator and must not be used
below atmospheric pressure.
- Please check the over-pressure in case of rapid compression.
