3.
Discharge
The pump shuts down. The pressure in the facility system causes more
water to be injected into the vacuum spray pipe and degassed. The water
level in the vacuum spray pipe rises. The gases released in the vacuum
spray pipe are released into the ambient atmosphere via the degassing
valves.
4.
Idling time
When the gas has been discharged, the device will remain idling until the
next cycle is started.
Degassing programmes
The device controller regulates the degassing process. The controller monitors
the operating states and outputs them to the display.
The controller provides 2 different degassing programmes for selection and
adjustment:
•
Continuous degassing
For continued degassing over several hours or days in a sequence of
degassing cycles without idling periods. This degassing programme must
be selected after commissioning and repairs.
•
Interval degassing
This comprises a limited number of degassing cycles. There is an idling
time between the intervals. This degassing programme must be selected
for continuous operation.
Make-up variants
The filling level in the tank is measured using the LIS Levelcontrol. If the level
falls below the pre-set minimum level, then at a specified level, make-up water is
fed in a controlled manner into the tank.
