Shaft detent
In combination with the valve block, the turbine has a shaft detent.
With the shaft detent the shaft is blocked when the bell disk is being
removed or fastened. For that, there are recesses in the rear end of
the hollow shaft. A pneumatically driven piston in the valve block
snaps into one of the holes.
Prerequisite for using the shaft detent:
- Switch of the atomizer (high voltage off).
- Stop the hollow shaft.
Triggering the shaft detent
Depending on the configuration of the application plant, there are
various options to trigger the shaft detent. Possible configurations:
- Atomizer is operated by means of the EcoAUC control system and
is not mounted on the elbow (1)
- Atomizer is operated by means of the EcoAUC control system and
is mounted on the elbow (2).
- Atomizer is operated with a different control system and is not
mounted on the elbow (3).
- Atomizer is operated with a different control system and is
mounted on the elbow (4).
Option (1):
The shaft detent is triggered via the visualizer of the control system.
Option (2):
The shaft detent is triggered via the visualizer of the control system
and a push-button on the elbow:
• Trigger shaft detent via control system.
• Push button on elbow.
The shaft does not move as long as the button is pressed.
