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.
