Align the extension worm so that it is centred.
Tighten the flange bearing. Turn the worm several times all the way through – it must be easy to move and it must
run freely.
Check whether the play on the intermediate bearings is distributed
adequately and uniformly on both sides.
13.2.2 Installing the pellet worm drive
4.) Install the drive motor
Place the feather key in the shaft groove (if necessary use the rubber
mallet to avoid damage) and turn the worm so that the drive motor can
be slid into the position shown.
Fasten the drive motor (fixing screw and shim)
Align the assembled fuel extractor in accordance with its final install position. Place the shim material under the
brackets at all support points. Check for horizontal alignment and correct if necessary. Fasten the acoustically
decoupled FE onto the storage room and boiler room floor.
Close all inspection covers!
13.3 Installing the transport hose
13.3.1 Equipotential bonding
The earthing strand of the conveyor hose must be connected to the fuel extractor
and it must be further connected to the earthing connection in the motor terminal
box, so that it is electrically conductive. This measure prevents static charges of the
conveyor hose!
•
Keep the hose lines as short as possible. Use as few redirectors as possible.
This minimises problems associated with different pellet sizes.
Standard conditions are: 20 m in length, 3 m height differential
(Max. height differential 4.5 m at a length of 15 m)
•
Maintain a minimum bend radii (hose bend) of 400 mm when laying out the hose line!
•
Contractions in the cross section are impermissible!
•
Do not walk on the hose – do not lay it out in the walking area
•
Route the hose in such a manner that it does not sag.
•
The hose can be routed vertically to room height without horizontal areas.
If there are greater height differences you must install a horizontal adapter with a minimum length
of 0.5 m. Thus in the event of power failure for example the transfer or plugging due to falling
pellets is prevented
