17. OPERATIONAL PROBLEMS OF THE SPRAYER
Working troubles are in experience mostly the same:
-
Bad joints in the suction area (between tank and pump) cause lower pump capacities
or prevent the sucking
-
A dirty suction filter can cause lower pump capacities
-
A dirty pressure filter causes a pressure increase on the pump and a reduction on the
nozzles
-
Larger particles can jam in the pump and lower the capacity
Fault Cause Control/remedy
No fluid is flowing from the
nozzles after you opened the
system Pouring in the sucking area
Air in the system
A dirty sucking or pressure
filter Check the valve before the
sucking filter.
Check the joints and the
suction hoses.
Check the membranes.
Rotate the handle of the
regulating valve in different
ways.
Clean the filters.
Irregular pressure Hydraulic mixer
Pump valves
Bad manometer Engage the hydraulic mixing.
Check the valves and their
wear.
Change the manometer.
Pressure drop Dirty filters
Wear nozzles
The valve on the tank lid
stuffed up
Air sucking while you have
few fluid in the tank Clean all filters and system
with clean water.
When working with powder
agents check if the hydraulic
mixer in on.
Check the nozzle flow and if it
is deviating, more than 10%
change them.
Close the valve of the
hydraulic mixer.
Pressure is raising The hydraulic mixer stuffed
up Clean the nozzle in the
hydraulic mixer.
Hard foam fluid Sucking air in the system
Too hard mixing Check the joints in the
sucking area
Close the hydraulic mixer
Lower the P.T.O. rpm
Add an anti foam agent
The fluid is flowing out of the
pump housing Crack in the housing or a bad
membrane Replace the membrane or
the pump.
Check regularly:
-
that you have clean suction and pressure filters
-
suction and pressure hoses for defects
-
that all seals are in place and in good condition
-
that the manometer is not stuffed and that it indicates 0 when the
pump is not working
