Spraying heads movement
At request, spraying head guidance powered by dou-
ble acting hydraulic cylinders or orbital motor can be
equipped (Fig. H1, H2, SI);
-
H1:
Hydraulic head with 1 vertical movement 90° (cylin-
der)
- H2:
Hydraulic head with 2 movements, of which 1 verti-
cal 90° (cylinder) and 1 horizontal 270° (motor).
- SI:
Hot house head Ø 400 with 1 horizontal 180° move
-
ment (motor).
For all drives please refer to the previous paragraph
“screw movements”.
Adjustments
It is also necessary to adjust the drive speed acting on the
throttle valve shown in Fig. a1 (for H1, H2 only 90°, screw
30° and 70°).
To control the drive speed of the 180° screw adjustable
throttle valves must be used (Fig. b1).
It is mandatory to use low speed, do not exceed 40 mm/
sec (2 l/min).
Specifically, throttle valves are fixed 0,8 mm (Fig. c1)
on the rotation of the head H2, only for 270° and for the
rotation of the head SI (180°). The hydraulic motor is sup-
plied with hydraulic brake that unlocks with a minimum
pressure of 25 bar, this motor is supplied with hydraulic
drainage (Fig. d1) that must be connected to the hydraulic
oil tank by means of a female quick-coupling.
For further details refer to the hydraulic diagram (chap.
15) and tables 37-38 (chap.16.2.6).
