Fan – Vacuum
The hydraulic fan for vacuum generation is
directly driven by the tractor hydraulics. The
tractor must be equipped with a flow control
valve to control the fan speed.
The hydraulic pump must deliver sufficient oil to
prevent the fan speed dropping, even when the
tractor speed drops or other hydraulic functions
are activated.
On the Maestro 1630, the vacuum fan is centrally
installed at the back of the main frame, and on
the Maestro 2430, 2422, 2420, 3215 & 3115 the
fans are installed at the end of each wing. The
fans on these models are driven in series and the
vacuum at each fan should be equal.
Vacuum is essential for the function of the single
grain metering unit. Vacuum is generated in the
fan and directed to the metering units through
the hose system and the frame integrated
distribution.
All components of the vacuum
system must therefore be
absolutely leak tight. Leaks
lead to metering errors.
Always pay attention to
residues in the system when
cleaning or preforming repair
work. Wear safety goggles,
breathing masks and safety
gloves!
The extraction of residues from the metering unit
can result in the depositing of harmful dust (seed
coating).
In order to protect the environment, any loose
dust is extracted during operation and placed on
the ground in front of the coulter.
Maintenance
•
Clean any dirt or deposits from the fan
blades to prevent unbalance and
damage to impeller and tapered bushing.
•
Check hoses and connections every day.
•
Depending on the amount of dust
developing during use, open the frame
regularly (weekly) and clean frame and
hoses with compressed air.
Damaged hoses, kinked hoses,
or defective connections must
be immediately replaced or
repaired.
