Enclosed Spring Mounts
Where a preference exists for the enclosed captive spring style of mount, we have responded by adding a new range to complement the existing Vibrostop open spring range.
For ultimate isolation performance this new range includes the DM and DH styles which provide spring compression up to 50mm.
To eliminate spring buckling, duplex springs sets are arranged in series separated by a steel plate
Un-necessary pre-travel is eliminated and stability is assured in this range as the mount is assembled in a pre-compressed condition. This range also features level adjustment such that the installation can be maintained perfectly level even if all mounts are not subject to exactly the same loading. 99% isolation can thus be achieved at frequencies as low as 14Hz (840rpm)
The range includes single and multiple spring mount to suit loads from 10 to 1650Kg. Throughout the range, the design deflection is either 25 or 50mm providing high and predictable levels of vibration isolation even at relatively low frequencies. To achieve these high deflections, all mounts are pre-compressed during assembly by 10mm or 25mm in the case of the high deflection. The maximum actual compression in these mounts is therfore actually either 25mm or 50mm in the case of the high deflection mounts.
Typical Applications.
This style of mount is used frequently in applications where high levels of vibration isolation are necessary such as in air handling systems, motor/generator sets and motor/pump combinations within, or on top of occupied buildings. A key application would include hospital theatre and metrology laboratory air handling units and motor driven fan units where noise and vibration must be precluded.
