GUIDE TO CHOOSING THE ANTI-VIBRATION MOUNTS

NOMOGRAPH

TO CHOOSE AN ANTI-VIBRATION MOUNT, YOU MUST KNOW:1. The static weight of the machine and the number of support

points with their respective loads;2. The excitation frequency determined by the rotating body at the

lowest r.p.m.;3. Installation of the machine to insulate: indicate if it is under

cover, subjected to wind or in areas with a high presence of salt mist or other

aggressive agents. It is essential to consider the temperatures to which the anti-vibration mounts will be subjected.

THE INSTALLATION IS CORRECT WHEN ALL THE INSTALLED MOUNTS HAVE THE SAME ELASTIC DEFLECTION.

If the resting points of different mounts are on the same level, the difference must be compensated for using special adjusters (JACKS).

The insulation diagram shows graphically the ratios between the elastic deflections in mm, the vibration speed in r.p.m. or cycles/mm and the degree of insulation as a %.

SOLECO ENGINEERING S.R.L. DECLINES ALL RESPONSIBILITY IN CASES WHERE THE INCORRECT INSTALLATION

OF THE SUPPORT IS DETECTED.

FOR ALL FURTHER INFORMATION ON THE ABOVE, PLEASE CONTACT OUR OFFICE ON +39 02 92 44 311.

EXAMPLE OF CHOICE OF ANTI-VIBRATION MOUNT:If you need to insulate a refrigeration unit weighing 6,234 Kg with a frequency of 1800 r.p.m. (30 Hz). The unit has six resting points with 1,039 Kg resting on each point (the load is evenly distributed). To achieve about 90% insulation, a deflection of about 4 mm. is nec-essary. The best anti-vibration mount to achieve this is the CFNNR1505016 60 ShA (image on page 6)

When choosing the anti-vibration mount, check that the maximum recommended load is higher than the load applied.
