SI Single
Impact Vibrator for Permanent Installation
The single
impactor delivers one impact at a maximum frequency of once
every three seconds through a five-port spool valve.
A timer is used to vary the cycle required. Single impactors
are most effective for sticky materials because they are less
likely than continuous vibration to cause packing in hoppers.
Low maintenance is guaranteed by a combination of a spring
less design and only one moving part. The single impactor
makes less noise and consumes less air than most air and electric
vibrators because there is no continuous blast of exhausting
air.
Like VMSAC and VMS,SI has a one-piece, rugged ductile
iron cylinder housing which decreases the weight of the vibrator.
It may be mounted on any appropriately sized mounting channel,
and comes complete with heavy-duty mounting fasteners and
a gasket.

Hammer
Formula
A X B X C = ft. lbs.
The
use of the hammer formula actually requires the use of a hammer
or sledge hammer to impart shock to the surface that is to
receive the impact. The tests should be conducted under
conditions as close to actual as possible.
A
= distance hammer travels ( 1 ft. minimum; 3 ft. maximum)
B = weight of hammer (Recommended weight. = 1 to 8
lbs. depending on the mass to receive the shock)
C = arm power (light = 3, medium = 6, heavy = 9)
Multipliers
by which arm power adds to the velocity or speed at which
the hammer head travels greater than gravity alone.

Had the
above example been an actual test and the 144 ft. lb. energy
been sufficient to satisfy the requirement, the next step
would then be to refer to the technical data section.
Using the 60 P.S.I. ratings, select the impactor that comes
closest to your test data.
In the case of the example above, the Model SI 1350 would
be best suited.
Note: the 60 PSI ratings will normally allow for sufficient
plus or minus power required for the actual use of the impactor.
