13.SPRAYING
13.1. DESCRIPTION OF TYPE OF T-JETS
Various types of jets are fitted; with a single or double head.
Generally they have a non-drip diaphragm and are made out
of brass, suitable for pressures up to 40 bar, some models are
nickel plated.

The jets can be equipped with different types of nozzles, changing the locking ring
nuts.
 The jets used normally have high volume, Ø20, ceramic plates.

The jets used normally have Medium
volume, Ø18, Ø15 ceramic plates.
 The jets used normally have Low volume, Ø12, Ø10, Ø8, ceramic plates.
All the jets normally used have three positions:
Spray - if the nozzle is pointing outwards, away from the turbo atomizer group, parallel with the non-drip
valve
Closed -
if the nozzle is at 90° with respect to the non-drip valve or, for the single jet if it is facing inwards
towards the turbo atomizer group
Nozzle second spray - when these are pointing towards the outside of the turbo atomizer group parallel
with the non-drip valve.
The nozzles are extremely important to obtain a correct distribution on the vegetation to be treated. Poor
quality or worn nozzles have a tendency to create unevenly treated strips.
The nozzles are produced in various sizes, to work with a precise pressure range, to create certain types
of larger or smaller drops; using nozzles for a purpose they are not envisaged for prejudices the precision
and duration of the nozzles.
14. CALIBRATING AXIAL FAN ATOMIZERS
Tables
N° 1 let you easily calculate the distribution in liters
/hectare of the atomizers with the standard fittings,
proceeding as indicated below:
a) Choose the table relevant to the turbo atomizer group of
the atomizer in question (the main reference is the number
of jets)
b) Find the distance between the rows of the vegetation
and the diameter of the nozzles used (ceramic plates,).
c) In the horizontal strip, choose the working speed and
the distribution in liters /hectare and on the vertical scale
find the pressure to use.
d) Adjust the pressure to obtain the treatment required.
If the distance between the rows is different from that in the
table you can easily calculate the distribution in proportion:
for example with a distance between the rows of 8 m,
divide the figure for the liters /hectare of the distance
between the 4m rows by half, with a distance between the
rows of 2.5 m double the figure for the distance between
the 5 m rows.
The last line of the table indicates the overall delivery of the fan.
To calculate the distribution in liters /hectare, use the following formula:
Vd = 600 x Q
I x V where: Vd = volume to distribute (Lt/ha)
Q = sum of the nozzles delivery (Lt/min)
I = distance between the rows (m)
V = tractor speed (Km/h)
