Sola PROSEM K BASIC Series - Vacuum Control for Mechanical Fan (Optional); Pneumatic Transport of the Fertilizer

ADJUSTMENTS

SUBMINISTRATE ENOUGH POWER TO THE
PNEUMATIC SYSTEM UNTIL REACHING THE MI-
NIMUM SUCTION POWER VALUES SPECIFIED IN
THE TABLE. CHECK THE DEPRESSURE VALUES
AFTER RUNNING THE FIRST 10 METRES.
VERY IMPORTANT: IN MODELS EQUIPPED WITH
MECHANICAL FAN, THE FAN’S SUCTION POWER
DEPENDS ON THE ENGINE’S RPM OF THE TRAC-
TOR. FOR THIS REASON, KEEPING A REGULAR
TURNING SPEED IS ESSENTIAL.
IF IT IS NOT POS-
SIBLE TO LOWER ENGINE REVOLUTIONS OF THE
TRACTOR, THERE IS OPTIONAL EQUIPMENT TO
REGULATE MECHANICAL FAN (SEE SECTION 6.4.1
VACUUM CONTROL FOR MECHANICAL FAN).
IN MODELS EQUIPPED WITH MECHANICAL FAN,
THE TIMING BELT SHOULD BE TENSIONED. IT
SHOULD BE CHECKED WHEN STARTING THE
SOWING SEASON, SINCE WEAR OR DAMAGE
COULD CAUSE A PRESSURE LOSS IN THE SUC-
TION CIRCUIT (SEE SECTION 9.3 FANS).
IF THE PRESSURE LEVEL IS LOWER THAN THE
ONE RECOMMENDED BY THE MANUFACTURER,
THE SEED DISC’S HOLES COULD HAVE A LACK
OF SEEDS. ON THE OTHER HAND, IF THE PRES-
SURE IS EXCESSIVE, DOUBLES COULD EMERGE
OR THE DISTANCE BETWEEN SEEDS COULD BE
IRREGULAR.
6.4.1 VACUUM CONTROL FOR MECHANI-
CAL FAN (OPTIONAL)
For regulate suction mechanical fan, operate the especial
screw located to Air reservoir
1- Loosen the nut (1, Fig. 6.27).
2- Turn the screw to change the fan suction (2, Fig. 6.27).
3- Tighten the nut to x the screw.

BEFORE STARTING WORK, ADJUST VALUE AND
CHECK THE FAN SUCTION.
6.4.2 PNEUMATIC TRANSPORT OF THE FER
TILIZER
In models VARIANT and TELESCOPIC equipped with fertilizer
unit with pneumatic transport of the exterior rows, adjust
the airow operating the adjusting valve placed in the air
reservoir (A, Fig. 6.26) and the venturi place at the fan’s air
outlet (B, Fig. 6.26).
THE AIRFLOW NECESSARY FOR THE FERTILISER
TRANSPORTATION TO THE EXTERIOR ROWS
CAN DEPEND ON THE TYPE OF FERTILISER AND
THE FRAME’S APERTURE CONFIGURATION.
WHEN THE ADJUSTING VALVE IS COMPLETELY
OPEN (A2, FIG. 6.26) AND THE VENTURI IS AT
POSITION 0 (B, FIG. 6.26), THE AIRFLOW FOR
THE PNEUMATIC TRANSPORT IS MAXIMUM.
WHEN NOT SPREADING FERTILIZER, THE AD-
JUSTING VALVE SHOULD BE CLOSED (A1, FIG.
6.26) AND THE FAN’S VENTURI SHOULD BE AT
POSITION 1 (B, FIG. 6.26).
