Boom Nozzle Control
Nozzle control is achieved using the Rapid Fire with
Rapid Flow system fitted as standard equipment.
Electrically activated air-solenoids control individual
boom nozzles and boom section on/off functions.
The nozzles have a standard spacing of 500 mm, but
250 mm distances can also be optioned.
3 Tier System (3TS)
The 3 Tier System (3TS) aims to give a wider
range of flexibility around application rate and
spraying speed. The 3TS effectively gives the driver
a much wider operating band whilst still maintaining
optimum droplet size.
The 3TS can be thought of as a three step gearbox,
or in the case of the 3TS Pro, a seven step gearbox.
Each nozzle type has an operating pressure band for
a given droplet size. As the first nozzle set, or tier,
reaches the top of its pressure band, the next larger
size nozzle tier is activated.
When the second tier reaches the top of its
pressure band, the first tier will be reactivated to
spray at the same time. This effectively gives three
operating bands.
The 3TS Pro option is an extension of this idea
using three different nozzle sizes and gives seven
effective bands of operation for even greater
application control. It requires an unlock code for the
Raven RCM which is provided when the feature is
optioned.
The Raven RCM controls the 3TS system. For
specific calibration and operating instructions, see
Raven RCM operation manual supplied.
Filtration
Filtration is a critical part of the sprayer’s
performance.
As standard, these sprayers are fitted with:
1 x Suction filter (32 mesh)
2 x Pressure filters (1 x 80 & 1 x 100 mesh)
Nozzle strainers (50 mesh)
Spray Pump
A centrifugal 400 L/min at 8 Bar spray pump is fitted
as standard. Positive displacement and oil backed
diaphragm pumps capable of 260 L/min can also
be fitted optionally. The normal operating range is
from 1 - 8 bar which is sufficient for efficient nozzle
performance.
• The maximum combined flow of all boom
sections is limited to 140 litres per minute, or 50%
of the pump flow, whichever is the lesser amount
with clean filters.
• Standard centrifugal spray pump: Running the
pump dry will cause failure. Care should be not to
operate at speeds exceeding 4200 rpm.
• Optional diaphragm spray pump: Care should
be taken to never overfill with oil or operate at
speeds exceeding 540 rpm.
• Do not exceed the maximum spraying pressure
of 8 Bar.
Chemical Induction
The method of chemical induction into your sprayer
is dependent on the optional chemical induction
equipment fitted to your sprayer.
Goldacres chemical induction equipment available
includes:
• Chemical Probe
• Chemical Induction Hopper
• 12 V Chemical Transfer Pumps
Booms
This machine can be fitted with a variety of boom
widths ranging from 36 to 48 metres. They feature
hydraulic lift, fold and individual wing tilt controllable
from the cabin. Goldacres TriTech booms feature
pitch, roll and yaw suspension in order to provide
a superior boom ride and assist in the efficient
application of chemical to your target.
Nozzles
As information regarding nozzles is specific to those
being used in your application, no specific reference
is made to nozzle application rates or nozzle types in
this operator’s manual. Goldacres suggest the use of
a current TeeJet or Lechler nozzle selection catalogue
for reference to nozzle sizes, outputs, spray patterns
and general spraying information. For more technical
information on the function of spray nozzles and
factors affecting their performance you can also use
the TeeJet ‘User’s guide to spray nozzles’.
The TeeJet & Lechler nozzle selection catalogue and
Users guides to spray nozzles are available from your
Goldacres dealer, or as a free download from the
TeeJet web site: www.teejet.com
