5.3. Use of Inocart NDT or HF equipment
5.3.1. Powder application
As the equipment has already been installed according to the safety rules (
) and the instructions given
(
), follow the steps described below:
•
Step 1
: Connect the ground cable of the cart to a conductive and earthed part of the spray booth; the ground
potential must be identical to that of the part to be powdered.
•
Step 2
: Electrically and pneumatically power the equipment.
•
Step 3
: Put powder in the pressure tank and close the lid with the clamps.
Tank under pressure in operation.
•
Step 4
: Switch on the
Inobox
control module (
) (ON button on the front of the module.
Configure the
Inobox NF
control module (
), for pressure tank operation.
The fluidizing outlet at the rear of the module must be plugged.
•
Step 5
: Choose the appropriate high-voltage feature or create a custom program.
•
Step 6
: Point the gun nozzle towards the booth and the part to be powdered and press the trigger.
5.3.1.1. In Non destructive Testing Powder (NDT) use
The
NDT pressure tank
is equipped with 2.7mm injector, 2.7mm ejector and 6mm inner diameter hose.
• Close the NDT tank shutter fully (position 0).
• Set the fluidization to setpoint 50. The dry developer flow rate can then be adjusted on the
Inobox
module or
directly on the gun by varying the injection parameter (0 to 100). If the flow rate is not sufficient, the control
shutter can be opened slightly.
5.3.1.2. In powder coating (HF) use
This equipment can be used for the application of difficult powders, very high flow rates can then be achieved.
However, the acceptable use limit of a conventional electrostatic gun (charge capacity) is reached at 15kg/h of
powder (250g/min).
The
HF pressure tank
is equipped with an ejector D: 1.7 mm, a 9/13 EVA hose and a suitable powder fitting
(
).
• Set the injection parameter (on the
Inobox
module or directly on the gun) to 80 and the fluidization to 43.
• Then adjust the powder flow rate by adjusting the position of the shutter on the pressure tank.
As an indication, with 6 m of 9mm hose and with a standard powder:
