15.5. Checking the liquid discharge
General:
The liquid discharge should generally be checked once each
year at the start of the season and also in the event of changes
in the liquid circulation or after replacing nozzles.
Before determining the liquid discharge, the
LIPCO GSG-NV
must be equipped with the proper nozzles for the operating con-
ditions.
Use either the nozzle chart for the
LIPCO GSG-NV
or that of a
nozzle manufacturer.
Select nozzles based on the calculated driving speed and the
desired distribution quantity so that the required nozzle dis-
charge is distributed in the pressure range between 7 and 12
bar.
The liquid discharge (l/min) now has to be checked at the unit.
Measurement:
Conduct the measurement using water only.
Fill the tank with water to a clearly visible mark. The marking
should preferably be in the narrowest point in the filling mandrel,
since the small diameter there immediately shows small changes
in the liquid level.
This provides for a more accurate measurement and also reduc-
es the time required for measuring.
After filling the tank with water, set the required pressure using
the buttons on the control box with the spray nozzles switched
on.
The pressure to be set is based on the calculated engine RPM
for the optimum driving speed.
Make sure that all lines in the system are filled with liquid. Air in
the system will result in an incorrect measurement.
