Inertia Base should be used where the machine to be vibration isolated produces large unbalanced forces which would result in excessive motion if supported directly on spring or rubber based isolators. They should also be used where the machine is subject to external forces or is inherently unstable. SMI Inertia Base come in several standard sizes as listed in our catalogue. However these bases can also manufactured to any size and specifications, even for heavier and more complex vibration isolation would normally recommend 6 isolators or more for exceptionally large bases.
Examples of equipment requiring Inertia Base are as follows:-
Reciprocating Compressors
Diesel Generating Sets
Engine / Dynamometer Test Rigs
Refrigeration Plants
Pumps (Particularly Belt Driven Types)
Features:-
Fully welded steel construction with integral concrete reinforcement fixed at 40 mm above bottom of frame.
Recessed height reducing corner brackets designed to accept standard SMI’s type SIOS open spring mountings.
Range of standard size frames available in three thicknesses 150, 200, 300 & 350 mm. Frame thicknesses not less than L/12 where 'L' is the longest side of the frame.
Finished with a single coat of red oxide primer on external surface only.
Due to policy of continual improvement, the specifications are subject to change without prior notice.
Measurements are subject to 5% tolerance.
To achieve good sound suppressions do not over load fitting.
