Vibration isolators for equipment & machinery

Vibration isolators double-acting type DZE

Manufacturer: Getzner Spring Solutions

 

Design

The Isotop® DZE, is a multi component vibration isolator made of stainless steel and two different damping materials: Sylodyn® and Sylomer®. It works for both compression and tension.
Due to its flexible damping properties, the product provides great sound isolation and reduces the amplitude of the dynamic load transferred onto the foundation.
The core is made of steel tube, welded to the base plate, allows for transferring horizontal forces and pulse-type loads caused by e.g. gusts of wind or sudden movements. These vibro-isolators are available in two sizes: DZE (with one or two damping inserts) and DZE Mini. The DZE size vibro-isolators are also available as blocks with two or four elements.

Application

The DZE vibration-isoators are selected according to the intendent load an the vibration frequency. The natural frequency of the vibration-isolator at nominal load is about 7 Hz for DZE and about 10,1 Hz for DZE Mini. They can transmit horizontal forces. The vibration-isolators are used for the foundation of:

• Diesel & petrolengines of all types,
• Compressors,
• Pumps,
• Cooling towers,
• High speed rotary machines,
• Heating ventilation and air conditioning systems,
• Machines placed on roofs,
• Power generators,
• Maritime equipment,                                                
• Mobile applications.

Information necessary for product selection

• Weight of the machine/device,
• Number and positioning of the fulcrums,
• Positioning of the centre of mass,
• Dimensions of the maschine/device,
• Load direction (vertical/horizontal),
• Lowest vibration frequency (No. of rotations or cycles).

Advantages

• Quick installation,
• The vibration-isolator is resistant to demage, suitable for tall and narrow, equipment when in a factory or mobile equipment and transporting,
• Long lifespan,
• Low natural frequency,
• Low height,
• High resistance to corrosion.
