7.7. Speed Adjustment
Changing the rotating speed for the turbine sets the rotating speed of the
machine. This is done by changing position of the conical turbine in its cone.
The speed can be adjusted while operating the machine by doing the following:
Note that the machine might rotate slower in cold climate.
1. Look at the top nut (pos. 113) through the cofferdam hole (E). The time it
takes for one turn can be measured with a wristwatch.
2. The speed should be 1-2 rpm. If not, adjust as follows.
3. Remove protective cup (A) (Key no. 25).
4. Loosen contra nut (B) (Key no. 30).
5. Set the adjusting screw (D) to get the desired speed by using a special short
Allen key no. 6 (tool 12061). By lifting the adjusting screw (D) the speed
will reduce and vice verse. The fastest speed that is possible to get is when
the turbine is running with a minimal gap between the turbine and the
sleeve. This is achieved by lowering the turbine until it stops and then raise it
approx. ½ a turn. Be
careful not to lift the turbine too high
, this would
make the machine stop.
6. After the speed has been set, tighten contra nut (B).
7. Recheck the speed of the machine step 1-2 and if OK check for leakages at
the adjusting screw. If leakages occur change O-ring (C, pos. 137).
8. Replace the protective cap (A).
Stop the machine while adjusting the screw, start again when the
contra nut are tightened. Check the speed, if not OK adjust again.
