Multiple layering of Bilz insulation pads can achieve significantly reduced natural frequencies and therefore considerably increase the insulation effect compared with a single layer of insulation pads.These pad sets are particularly suitable for large machines and sprung foundations.The vibration insulation and damping properties of these insulation pads remain unchanged even after years of dynamic loading. Bilz insulation pads are resistant against the most common greases, oils, coolants,cleaning agents as well as acids and alkalis.

Application

• Effective insulation pads for highly dynamic machines and foundations.
• The permissible load capacity of a pad lies between 5 and 40 Kg/cm2 depending on the application. The number and size of the insulating layers and the required distribution of the pad sets is determined specifically for the application by Bilz.

Bilz scope of supply and services
8 x Bilz FAEBI® 580 HD with mechanical-pneumatic level control MPN-LCV
Planning services

• Creation of the foundation
• Static calculations
• Formwork and reinforcement plans
• Steel and steel bending schedule

Requirements

• A maximum of 3 weeks loss of production.
• Special shape 5 corner
• Tight space conditions and entry to the inspection channel through the foundation block
• Extremely small allowable horizontal movements of the machine
• Reliable source isolation for suppressing the disturbing vibrations in the adjacent building, 2. floor, from 10 Hz.

The foundation insulation using low-frequency BiAir membrane air springs enables an optimum insulation effect. Unlike with the use of pad sets or steel springs the adjustable level of the foundation block automatically resets itself in response to load changes through the level control.

8 x Bilz membrane air springs BiAir® 4-ED with mechanical-pneumatic level control MPN-LCV.

Particular general conditions
The processing accuracy required of the roller grinding machine cannot be met due to disturbing influences from adjacent machines and an overhead crane rail. Large travel distances and tools weighing up to 10t cause large load changes that necessitate the use of a fast, mechanical-pneumatic level control with a level accuracy of ± 0.1 mm.
