 er le macchine a turbina utilizzate a piu di 20m/h aggiungere 0,5 bar alla pressione d'ingresso per mantenere gli stessi valori di
pluviometria.
Pour les enrouleurs turbimec utilises a plus de 20m/h ajouter 0,5 bar a la pression entree machine pour conserver les memes
valeurs de pluviometrie.
For turbine machines running up to 20m/h add. 0,5 bar at the inlet pressure to maintain application of water.

- Tachometer:
- The Tachometer (fig.41) is the instrument which is used to read the trolley speed in meters / hour (m/h).
- Read the speed by finding the point of intersection
between the needle and the line representing the layer
on which the PET tube is, and follow the curved line
to the nearest number.
For a speed of 20 m/h
- Unrolled, the needle is at 20
- Rolled up, the needle is at 13 (follow the curved line to 20)
hose-reel is unrolled
hose-reel is rolling up
- The depth of water applied by the hoseReel is regulated by the speed the sprinkler moving over the
ground (fig.38). It is also affected by the amount of water being discharged by the sprinkler head.
- Example: Your hosereel is
an St5 110 TG 380
Sprinkler’s type is a Ranger
with Ø28 for nozzle.
Your turbine pressure
gauge is on 9 bar.
The travel speed is
20 m/h
- Note that the application
rate is 40 mm.
- The amount of water discharged is
determined by the sprinkler nozzle
size and the water pressure. These
two factors are determined by the
available water and the capability
of the water pump at the water
supply. The selection of the sprinkler
nozzle needs to be made based on
the water supply and pump
performance.
- After the nozzle has been selected, the “depth of water” decal on the machine can be used to determine
the travel speed settings to give the desired depth of water. See the example.
