Function

 

 

Automatic spray guns are used for the

n

automatic coating/marking of surfaces

n

dosing of fluids

n

placement of adhesive or marking points

Typical spray fluids are paints, dyes, adhesives, glazes, enamels, debonding agents, etc.

The spray fluid is fed into the automatic spray gun under pressure. This pressure is typically gener-
ated by pumps or pressure containers. The automatic spray gun is controlled via compressed air.

Upon opening, the control piston charged with compressed air initially opens the air nozzle and
then with a short delay the fluid nozzle of the spray gun. Upon closing, initially the fluid nozzle and
then the air nozzle is closed in order to prevent a subsequent dripping of the spray fluid.

For the precise control of the automatic spray gun, electrically-activated solenoid valves can be
used, for example. Switching times of 60 ms can be achieved this way.

The spray fluid is atomised using compressed air. The geometry of the spray jet and the sprayed
quantity of the spray fluid can be adjusted with the following measures:

n

Selection of the air and fluid nozzle

n

Changing of the atomisation air pressure

n

Changing of the spray fluid pressure

n

Adjustment of the needle stroke on the regulator of the automatic spray gun.

The automatic spray gun also features the following additional characteristics:

n

Head section only in aluminium, hard-coated

n

Head section with lower fluid connection

n

Main element with flat jet regulator
or with flat and round jet regulator
