Installation
5. Lock the adjusting nut with the locknut.
6. Switch on the conveyor belt system and observe the cleaning
effect of the scraper blades. Take care to ensure that the scrap-
er blades touch the conveyor belt gently and in a vibration-free
manner.
Adjusting the air tensioner
In order to generate the force to press the scraper blades against the
conveyor belt, a compressed air bellows is used in air tensioners at
every installation console. The setting of the scraper and the press-
ing force are controlled automatically with the help of the lockable
ballcock with automatic bleeding (see Fig. 18, page 30).
1. To adjust the MARTIN
®
DT2H scraper with an air tensioner,
pressure must be applied to the bellows in accordance with Ta-
ble 3.
2. When using a pressure control device, connect the lockable
ballcock outside on the housing with the compressed air sup-
ply. Switch on the compressed air supply and open the ball-
cock. The scraper is raised and the scraper blades touch the
conveyor belt.
3. Unlock the pressure-relief valve in the pressure control device
and the adjust the pressing force. The pressure-relief valve is
fitted with automatic bleeding, as a result of which the pressure
stabilises automatically. After every change in the setting, wait
for some time so that the pressure peaks may get reduced.
4. If the desired pressing force is adjusted, block the pressure-re-
lief valve and close the housing.
