4.1.8 CONTROL UNIT
The control unit consists of a pressure
regulator (
R
), and a distributor (
D
).
At the pressure regulator is installed a
manometer (
M
) which allows to view the
pressure within the circuit. Using the
regulator it is possible to adjust (depending
on the number, the type of nozzles,
processing speed and other parameters), on
pressure operation of the
machine .
In case of anomalies in the circuit, which
can generate strong pressure safety, it
intervenes a safety valve calibrated
according to models.
Pressure regulators may be manual
(mounted on the atomizer fig 1, or
tractors (model BYMATIC fig 2) or
electric (with control panel placed in the
cabin), in the latter case it is provided a
distance gauge fitted with a separator
because for security reasons it's not
possible to bring liquids in pressure in
the signal box. If the tractor is equipped
with a sealed cabin it is compulsory to
use electric controls.
Also for this device is attached related
manual.
4.1.9 DISTRIBUTORS
The Distributor (D) consists of gate valves or
cocks which convey the fluid in various directions.
