Operation
1.
Set the one-hand lever of the mixing unit to "Stop" and close the flushing
ball valves on the mixing unit.
2.
Make sure that all compressed air regulators are turned down completely.
3.
Place the suction for the flush pump into the cleaning agent container.
4.
Point the outlet opening on the static mixer into an empty container to be
able to collect the escaping material mixture.
5.
Open the compressed air shut-off valve.
6.
Open the flushing ball valves on the mixing unit.
7.
Set a low pressure on the compressed air regulator of the flush pump so
that the pump starts slowly.
8.
Adjust the running speed for the flush pump to approx. 15 double strokes
per minute.
5.1.2 Flushing out the remains of the test substance
Following assembly, the machine was tested with a test substance in the
factory for proper function. During initial commissioning, it is therefore
necessary to first fully clean the machine to flush out the remaining test
substance (see chapter 5.7 on page 29).
5.1.3 Filling the machine with processing material and ventilating
1.
Establish the material supply:
➤
For proportioning pumps that are supplied with material via a suction
hose, place the suction hoses into the corresponding material drums for
components A and B.
➤
For proportioning pumps that are supplied with material via hoppers, fill
the material for components A and B into the corresponding hoppers
and open the stop cocks at the material inlet of the proportioning pumps
as required.
2.
Hold the mixing unit, directing the material ejection against the inner wall of
the collecting vessel.
3.
Set the one-hand lever of the mixing unit to "Injection".
4.
Let the injection pumps start up slowly. Slowly adjust the air inlet pressure
to approx. 1-2 bar for this.
5.
As soon as mixed material (component A and B) consistently escapes out
of the mixing unit, the filling and venting process is completed.
Set the one-hand lever of the mixing unit to "Stop"
The proportioning pumps stop!
6.
In order to be able to check the material reactions, fill a suitable test
container (approx. 0.2 l) with the material to be processed.
Repeat work steps 3-5 of this chapter for this.
7.
Flush the mixer block immediately until clean cleaning agent runs out
