Connect up the power unit in bypass flow with the tank that is to be cleaned.
After the unit is switched on, the filling pump
(3)
begins to convey the fluid
from the tank through the suction filter
(1)
into the vacuum column
(5)
. The
vacuum pump
(16)
sets up the negative pressure in the vacuum column
(5)
required for dewatering and degassing.
The negative pressure is regulated by the negative pressure setting
(14)
,
continuously measured at the negative pressure sensor
(15)
and displayed
on the SIMATIC operating panel in the control cabinet.
The fluid percolates downwards in the vacuum column over a special tower
packing and collects in the lower area. After reaching the Max level
[02]
, the
evacuation pump
(7)
switches on and now permanently conveys the fluid out
through the fine filter
(9)
to the outlet.
As a result of the greater volume flow of the evacuation pump, the filling level
in the vacuum column drops down to the Min level
[01]
. Once this is reached,
the return valve (2/2-way solenoid valve)
(26)
opens and a partial volume
flow is returned into the vacuum column. The return valve (2/2-way solenoid
valve)
(26)
closes once again after the Max level
[02]
has been reached.
Air is drawn in through the air filter
(13)
as a result of the negative pressure in
the vacuum column
(5)
. In the counter flow, this air absorbs the moisture of
