Pneumatic Linear with External Piston - DOV-AL
Series
Description
DOV-AL
Series Pneumatic Linear Vibrators with External Piston
are similar to the Standard DOV design but have anodised aluminum housings
which can be operated on greatly reduced lubrication and in some cases
can be lubrication free. Linear vibrating force is delivered by a noiseless
air cushioned piston. Frequency and amplitude can be regulated independently.
Using additional masses the vibrator is able to work at low frequencies
and to generate large amplitudes. DOV-AL linear oscillating vibrators combine
the advantages of low frequency rotary vibrators (large amplitudes) with
those of magnetic vibrators (adjustable amplitudes). Additionally, they
have the advantage of being able to select the most suitable frequency
to obtain optimum results.
Application
These compact robust range of linear vibrators, available
in 4 popular sizes, are suitable for use in a wide
number of applications, to assist in the flow and
control of many materials. The following being some
of the more common:
- Feeders: Natural Frequency Feeders. Particularly good
for feeding light materials where large amplitudes
are required.
- Tables: For packing industry, foundries for core making,
up to loads of 1000 Kgs/2200 Lbs.
- Screens: Very effective
on small screens for materials of low specific gravity,
granular materials and powder.
- Hoppers: Certain applications
where larger materials bridge. Not suitable for sticky
or ratholing materials.
Accessories
Silencers and suitable air inlet fittings are supplied
with these vibrators. Please allow us to quote you for
other fittings and control equipment.
General Maintenance
The DOV-AL model vibrators have a long life with no undue
piston or cylinder wear when minimal lubrication is used.
The air line filter and lubricator, if used, must be
inspected and cleaned at regular intervals. Dirt or contaminated
oil will slow down or stop the vibrator.
