We all know that automatic spray guns generally have two to three air inlets, but many people do not know the function of each air inlet very well. Today, let's talk about the functions of the three air inlets FAN, CYL and CAP of the automatic spray gun.
CYL: Control the switch of the spray gun, control the gun needle to close through the solenoid valve, the oil will be discharged when ventilation, and the power will be closed.
CAP: Atomization control, through the air pressure regulator to control the effect of atomization. The larger the paint flow, the larger the atomization pressure.
FAN: Width adjustment is also a sector adjustment. Adjusting its size can change the size of the sector. There is an adjustment knob on the spray gun, and there is also a remote pressure regulator.
We already know the basic function of each air inlet of the automatic spray gun, but we also need to understand how to adjust it.
First turn on CLY to adjust the air pressure in the range of 0.3Mpa-0.5Mpa to keep the air pressure stable. Then the air pressure of the CAP needs to be adjusted by the size of the existing flow until the automatic spray gun atomizes uniformly and finely, and the atomization that comes out at this time is conical. Finally, adjust the air pressure of FAN to adjust to the suitable width. Of course, when we actually work in production, we also need to reasonably arrange the flow and air pressure according to the spraying requirements of the current product.
