1 Function and identification

1.1

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.
For the precise control of the automatic spray gun, electrically-activated solenoid valves can be
used, for example.
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
Optional equipment:
Automatic spray gun:
n Main element (stainless steel or aluminium, chemically nickel-plated, PTFE-coated)
n Needle stroke setting
n Circulation connection
n Double controller (interruption of the fluid feed through spring force or pneumatically)
