When using freeze-dried air and
under extreme ambient conditions
the installation of an upstream
lubricator is required.
Operation with very short stop intervals
In case of operation with very short stop intervals (ā 2 s.), it is possible
that the linear vibrator does not start immediately. The reason for this is
that the time is too short for the piston to be pushed into the end-position
by the spring (units group 1), or by gravitational force (units group 2).
Special versions are available for such applications.
Regulating the amplitude:
The amplitude can be regulated by
throttling the exhaust air (installation of
a throttle in the discharge port).
With this the linear force can be
reduced .
The frequency remains almost
constant.
Recommendation: Reduce the
amplitude only down to approx. 50%.
Below this value starting problems may
occur.
Regulating the frequency:
The frequency can be reduced by
throttling the air pressure at the inlet
port of the NTS.
This also reduces the linear force.
The amplitude remains almost
constant.
At constant main pressure the
pressure can be reduced by a throttle,
but more precisely by a pressure
regulator.
Checklist for commissioning:
1) Check hose connections before opening the compressed air supply.
2). Adjust the desired frequency on the pressure regulator.
3). Adjust the desired amplitude by throttling the exhaust air.
4). Adjust the lubricator, if existing.
The fastening screws for the vibrator must be retightened or checked
after 1 operating hour.
