Service, Maintenance - NetterVibration NTP Series Operating Instructions Manual

When using dried compressed air and
under
conditions,
upstream mist lubricator is compulsory.
Regulation of Amplitude:
The amplitude can be regulated by
throttling the exhaust air (throttle fitted
in air discharge line).
This reduces the centrifugal force.
The frequency remains approximately
constant.
Recommendation:
amplitude by up to approx. 50%. Lower
values can cause start-up problems.
Checklist for Start-Up:
1) Check hose connections before opening the compressed air supply.
2) Adjust the mist lubricator, if necessary.
3) Set the desired frequency on the pressure regulator, if necessary.
4) Set the desired amplitude by throttling the discharged air, if
necessary.
The vibrator attachment screws must be checked after 1 hour of operation
and tightened, if necessary.

8 Service, Maintenance

Please observe the safety regulations in chapter 4 when servicing
the device.
Retightening:
Screwed connections should be retightened after 1 hour of operation
(after initial start-up) and then checked at regular intervals (generally
once per month) and tightened, if necessary. The specified torque must be
observed (see chapter 6).

Regulation of Frequency:
The frequency can be regulated by
reducing the air pressure before it
enters the NTP.
This also reduces the centrifugal force.
The amplitude remains approximately
constant.
