Function description
After the FAM has been switched on, the filter pump unit
1
starts to draw the fluid
from the tank to be cleaned and transfers it with a flow rate of 15 l/min into the
vacuum chamber
3
. At the same time, the vacuum pump
7
creates a vacuum inside
the vacuum chamber. The fluid to be cleaned trickles downward through special
filling materials. These filling materials are responsible for forming a thin fluid film
and reducing the speed of the trickle. At the same time, a stream of air flowing
upward from below against this current assimilates the water from the fluid and
conveys it to the outside by means of the vacuum pump. Once level
02
is reached
on the level switch, emptying pump
5
is switched on in order to convey around 15
l/min to the outlet. The filling level falls until level
01
is reached, after which solenoid
valve
6
switches on and the two pumps convey into the vacuum chamber. The filling
level continues to rise until level
02
is reached, after which the solenoid valve shuts
back off again, the filling level falls again, etc.
After actuating the stop switch, the filter-pump unit stops and the evacuation pump
empties the vacuum chamber.
Switching the main switch to "OFF" renders all engines and valves voltage-free.
The vacuum pressure, and thus also the air flow rate, in the vacuum chamber is
regulated with the throttle valve
8
.
For the purpose of odor reduction, the suctioned airflow is fed to the vacuum pump
via a condensate separator, which is filled with vacuum pump oil (VE101). The
exhaust air from the vacuum pump is released back into the environment via an
active carbon filter.
