The powder paint is deposited in the NDT or HF pressure tank:
• The injection air (check valve Item
5
) is used to pressurize the
NDT or HF pressure tank
.
• The powder contained in the tank (Item
3
) is fluidized at the fluidizing cup by means of air (fitting on the
fluidizing cup
6
) passing through the porous cone
7
).
• The electric vibrator (
4
) prevents powder accumulation in the porous cone.
• The air jet from the injector carries the powder towards the ejector tube.
•
In NDT version
: The shutter (
2
) which more or less closes the powder ejector tube must be set to "0" at start-
up. The dry developer flow rate is adjusted using the injection air on the Inobox control module or directly on
the gun using the + and - keys. If the flow rate is not sufficient when the injection parameter is at 100, it can be
increased by opening the shutter (
2
) slightly using the lever (
1
) located on the cover.
•
In the HF version
: On the
Inobox
control module, the injection setpoint must be set to 80 and the fluidisation
to 43. The powder flow rate is adjusted using the lever (
1
) on the cover. This pilots the shutter (
2
) which more
or less closes the powder ejector tube. The adjustment can be refined by changing the injection air set point on
the
Inobox
module or directly on the gun.
In no case should the maximum filling height of the tank exceed a threshold of 10 cm below
the end of the ejector tube.
