Installing a piston Electric
Vibrator is not a simple matter of bolting it to your equipment, and
supplying compressed air. For a vibrator to perform effectively and safely,
there are several necessary components. You will need, at minimum:
- Mounting
Assembly
- Airhose
- Safety Cable
- Lubro-unit
combination Filter-Regulator-Lubricator (if Tefkote option is chosen, no
lubricator is required)
- On/Off
Controller of some kind
- Solenoid
Valves
- Pneumatic
Timers
- Electronic
Timers
- Specialized
on/off controllers
- Dessicant
Dryer
As always, the Electric
Vibrator Sales Team is available to assist you in configuring a solution
that fits the requirements of your application, your facility, and your budget.
While not all options of Electric
Vibrator are available for all sizes or all types, we can accommodate most
requirements. This is a list of our most commonly requested options.
Long Stroke: Available on limited
sizes, long stroke Electric Vibrator
can be mounted on the same mounting plate as their standard counterparts, but
feature a higher force output. This is useful in retrofits requiring
higher force than the existing model can provide. For a chart
of possible retrofits (including other brands), view our Long Stroke
Retrofit Chart.
Tefkote: This is an internal coating
that allows piston Electric Vibrator to
be used without lubrication. It is useful when Electric Vibrator will be used in an
environment where exhaust air containing lubricants is undesirable, such as
food and pharmaceutical manufacturing, or anywhere that personnel will be in
close proximity. This option also provides protection from high temperature
environments, allowing piston Electric
Vibrator to be used on mounting surfaces may be hotter than normal due to
process or material temperature. The Tefkote option is available on most of our
piston Electric Vibrator sizes and
types, including IMP, AC, SI, QI, QSI bin vibrators, and HCV and QMC
railcar vibrators.
Start Springs: Start Springs are used
to ensure that a Electric Vibrator's
piston returns to the start position when the air source is turned off. This
option should only be used when a Electric
Vibrator is mounted such that the piston is within 20 degrees of
horizontal. Otherwise, gravity will pull the piston back into the proper
position, and the spring is not needed.
Tapped exhaust is useful when exhaust air is not ideal in the
immediate area of the Electric Vibrator.
With the tapped exhaust option, you are able to attach tubing or piping to the
threaded exhaust port in the Electric
Vibrator, and route it to an alternate location. Some larger models may
require dual tapped exaust.
External Coatings: Houston
Electric Vibrator offers special
corrosion-resistant or food-grade external coatings upon request.
Impacting Electric Vibrator: This is a
continuously running Electric Vibrator,
meaning that the piston continues to move back and forth as long as air is
supplied. The piston actually contacts the bottom of the vibrator bore at the
end of each stroke, creating an "impact". This is the most powerful
option, but also the loudest.
Air Cushioned Electric Vibrator: This is a
continuously running Electric Vibrator,
meaning that the piston continues to move back and forth as long as air is
supplied. The piston does not make contact with the bottom of the Electric Vibrator bore, but oscillates
back and forth, creating an "air cushion" at each end of the stroke.
This is the least powerful option, but the quietest.
Quiet Impact Electric Vibrator: This is a
continuously running Electric Vibrator,
meaning that the piston continues to move back and forth as long as air is
supplied. The piston is tipped with a rubber bumper, and actually contacts the
bottom of the bore at the end of each stroke, creating an "impact"
which is quieted by the rubber tip.
Single Impact Electric Vibrator: This is a timed
impact Electric Vibrator, meaning that
the piston only hits once each time air is supplied. It stays at the end of the
stroke until air supply is turned off and the Electric Vibrator is allowed to exhaust
and reset to the start position. Like the Impacting Model, it does actually
create an "impact" each time the Electric
Vibrator is energized. However, the timing of each impact is controlled by
way of an electronic timer, PLC, pneumatic timer, or manual on/off control.
Models of this type will end with the "SI" designation.
Quiet Single Impact Electric Vibrator: This is a timed
impact Electric Vibrator, meaning that
the piston only hits once each time air is supplied. It stays at the end of the
stroke until air supply is turned off and the vibrator is allowed to exhaust
and reset to the start position. Like the Quiet Impacting Model, it does
actually create an "impact" each time the vibrator is engergized, and
the rubber tip of the piston quiets the noise from that impact. The timing of
each impact is controlled by way of an electronic timer, PLC, pneumatic timer,
or manual on/off control.
