FAM Function description
After the FAM has been switched on, filter pump unit
1
begins to suction fluid out of
the tank to be cleaned out and to pump it through the filter into vacuum chamber
3
at a speed of 10 l/min. Vacuum pump
7
begins at the same time to build up the nec-
essary vacuum. The fluid to be cleaned trickles downward through special filling ma-
terials. These filling materials are responsible for forming a thing fluid film and reduc-
ing the speed of the trickle. At the same time, a stream of air flowing upward from
below against this current takes up the fluid and conveys the 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 in the vacuum chamber is regulated with the regulating valve
8
.
Possible Applications
The electric control supports several operation modes e.g.,
•
the FAM is switched On/Off at a control room.
•
the general malfunction message can be transmitted to a control room
•
the operating status can be queried
•
the FAM can be switched on/off by a level sensor in the transfer by pumping
operation mode.
