Spring devices can be used for solving a wide range of vibration isolation problems.A typical industrial application is the base isolation of heavy duty machinery like presses or forge hammers. In power plants spring devices are installed to isolate coal mills, gas- or diesel engines, turbines, pumps or condensers. Compressors or big fans are other examples where the isolation with spring devices avoids that the vibration induced by this equipment – the source of the vibration – is transmitted to the environment (isolation at source).
Spring devices can also be used to isolate a vibratory system against vibrations induced by the environment (isolation of recipient). Examples for this are the base isolation of precision equipment or structures like buildings against vibrations induced e.g. by traffic.
In any case base isolation with spring devices is a state of the art approach to reduce the effects of unwanted vibration thus allowi
- protection against shocks and continuous excitation for man, machines, structures and building
- control of operational vibrations within the admissible limits
- reduction of wear and tear of machines, equipment and structures
As a consequence, with a good base isolation concept for e.g. a big hydraulic press,the foundation of the machine may be designed in a significantly lighter way. This concept allows the installation of vibrating equipment in almost every location and it allows to considerably reduce the cost of the foundation itself.
