Function
After the FAM is switched on and the purification operation starts, the 2/2 directional
valve
(1)
and the vacuum pump
(4)
configures the required vacuum. Because of this
vacuum, the fluid which is to be purified is sucked into the vacuum chamber
(2)
. The
fluid trickles downward over a special tower packing. The fluid is collected in the
bottom of the reactor. After reaching the level sensor
02
the evacuation pump
(5)
is
switched on and pumps the fluid via the fluid filter
(7)
towards the outlet. At the
same time, the 2/2 directional valve
(1)
closes and the fill level in the vacuum
chamber sinks to the level switch
01
. When this occurs, the 2/2 directional valve
(1)
opens and and fluid flows from the inlet into the vacuum chamber until it reaches the
level switch 02. The 2/2 directional valve closes and the procedure begins again.
The vacuum in the vacuum chamber (2) sucks air out through the air filter (3). This
air absorbs the moisture of the fluid and is then sucked out by the vacuum pump
(4)
.
With a special cooling system
the air is cooled and partially dried within the vacuum
pump. The resulting condensed water is fed to the operating water using the water-
operated vacuum pump. If more water is extracted than can be used by the pump
(evaporated), it is emptied via an excess flow valve
(10)
into the condensate water
container
(6)
. If less water is extracted than can be used by the pump, it is manually
refilled by the automatic water connection
(9)
. The fill level is monitored
automatically by a level switch.
1
Water ring vacuum pump version only (FAM-x-x-x-x/xxxx-x-x-x-
S/SW
-x-/x). In models with a rotary
vane pump (FAM-x-x-x-x/xxxx-x-x-x-
D
-x-/x ), water is discharged from the vacuum pump as water
vapor.
