5 Automatic spray gun M -10 ENGLISH 1 Function and identification 1.1 Function Automatic spray guns are used for the automatic coating/marking of surfaces dosing of fluids 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 generated 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. Switching times of 60 ms can be achieved this way. Upon opening the control, the control piston charged with compressed air first opens the atomizer air valve and then with a short delay the fluid nozzle of the spray gun. Upon closing the control, first the fluid nozzle and then the air nozzle is closed in order to prevent a subsequent dripping of the spray fluid. 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: Selection of the air and fluid nozzle Changing of the atomisation air pressure Changing of the spray fluid pressure Adjustment of the needle stroke on the regulator of the automatic spray gun The automatic spray gun consists of the following materials: Component Head section Control section Main element Needle Nozzle Seals Material Stainless steel or anodised aluminium Aluminium anodised Stainless steel Various plastics GB 5
