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 using the negative pressure setting (14),
measured continuously using the negative pressure sensor (15) and
displayed on the control panel in the control cabinet.
The fluid percolates downwards in the vacuum column over a special tower
packing and collects in the lower area. The evacuation pump (7) switches on
after the Max [19, center] level is reached.
As a result of the higher flow rate of the evacuation pump, the filling level in
the vacuum column drops up to the Min [19, bottom] level. 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 the again after the Max [19, center] level is
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
the fluid and is then drawn off by the vacuum pump (16) through an oil mist
separator (17).
