Mode of operation
After being switched on, the motor pump assembly (4.0), depending on the
fluid level, starts to suck the fluid in the vacuum column from the tank via the
intake strainer (4.02) or from the vacuum column and the switch valve (3.85).
The volumetric flow rate is divided in the volume flow divider (4.54). One part
is transported into the vacuum column (3.0) via the optional heater (8.0), the
other back into the tank via the fluid filter (6.0).
The vacuum pump (7.0) builds up the underpressure (vacuum) required for
dewatering and degassing in the vacuum column (3.0).
The underpressure is set using the needle valve (3.68) and shown in the
pressure gauge on the cover of the vacuum column (3.0).
The fluid percolates downwards in the vacuum column (3.0) through special
fillers and collects in the lower area. After reaching the "Max" level (3.38), the
switch valve will switch over (3.85) and the motor pump assembly (4.0) will
now suck the oil from the vacuum column (3.0).
Air is drawn in through the air filter (3.73) as a result of the negative pressure
in the vacuum column (3.0). This air absorbs the moisture of the fluid and is
then sucked out by the vacuum pump (7.0). The gases removed from the
fluid as well as the water that is absorbed is expelled (as water vapor) from
the vacuum pump.
The saturation level of the aspirated fluid is continuously measured with the
optional AquaSensor (12) and displayed on the control panel. The saturation
level indicates what percent of maximum possible water is dissolved in the
oil. A value of 0% would indicate water-free oil and 100% would mean oil that
is completely saturated with water.
Once the STOP button is pressed, the unit runs until the "Min" fill level in the
vacuum column is reached. The run-down phase status is shown in the
display.
Exception: If the integrated heater is switched on, then a cooling phase of
60 seconds will intervene during which the heater is first shut off.
If the fill level "Min" in the vacuum column is reached, the power unit will be
switched off.
The FAM is voltage-free downstream from the main switch when the FAM is
switched off with the main switch.
