21.3 Water from water tank
Fig. 22: Booster pump
Fig. 23: Suction strainer complete with
filter screen
Booster pump AV 3000, 230 V, 1 Ph, 50 Hz, 0.6 kW complete
article number 00493686
The connected booster pump ensures the required water pressure
of at least 2.5 bar.
NOTE!
When working from the water tank, the strainer
with filter screen (article number 00136619) has to
be positioned upstream (bleed booster pump).
22 Setting water factor
22.1 Pre-setting the water flow rate
1
Fig. 24: Needle valve
Adjust the expected amount of water at the needle valve (1):
1. Close the needle valve.
2. Then open the needle valve by two turns.
3. In this position, the water flow rate is approx. 200 ltr/h.
4. Using the needle valve, the material consistency can be
adjusted.
NOTE!
Turning the needle valve in clockwise direction
causes lesser water flow so that the material
becomes viscous and vice versa.
The specifications of the material manufacturer
must be observed here.
NOTE!
Any interruption in the mixing operation results in a
slight irregularity in the consistency of the material.
This irregularity normalises by itself as soon as the
machine has been working for a short while.
Therefore it is important not to change the water
quantity for each irregularity. Wait until the
consistency of the material has set again.
