Principle of gun

The principle of electrostatic spray gun:

The air hose supplies air to the spray gun. Some of the air is used for turbine operation and the rest is used for spray fluid atomization.

The turbine generates power, which is converted into a high-voltage current by a switch that can be used by the spray gun electrodes. The pump is used to supply fluid to the hose and gun. The fluid is charged electrostatically as it passes through the electrodes. The charged fluid is attracted to the grounded workpiece, surrounds the workpiece and is applied uniformly to all surfaces.

The principle of automatic spray gun:

Automatic spray gun inside with a pneumatic piston, piston top with a stainless steel needle injection, while behind the piston is equipped with a group of high tension spring, when the compressed air supply to stop supply, spring to resist the piston and the injection needle ahead, the injection needle work closely with the nozzle with high precision ground to prevent liquid through; On the contrary, when the compressed air is supplied, the pressure of the compressed air pushes the piston open, which creates a gap between the spray needle and the nozzle for the liquid to eject, and the liquid after ejecting immediately contacts the atomizing air to produce the atomizing effect.

Principle of manual paint spray gun:

Pressure type manual spray gun:

The pressure type manual spray gun is mainly used to supply paint from an external paint supply pump or pressure tank/barrel. This type of paint supply pressure can supply paint to several spray guns at the same time. This spray gun will paint nozzle and air cap center design in the same plane, so that the front of the recoating nozzle will not form a certain negative pressure.

Gravity type manual spray gun:

Gravity type manual spray gun is also people do on the pot spray gun, mainly using gravity to paint from the pot traction to the nozzle below, and then wind to carry out a comprehensive spraying, can carry out a comprehensive spraying, its main benefit is to be able to make a small area repair, very save paint.

Suction type manual spray gun:

Suction type manual spray gun principle mainly using high speed air flow of the spray gun parts vacuum state, because of its produce suction from the paint pot suction in the nozzle, and atomization to overflowing, a major role in the coating of large area, its advantage is that the paint has good atomization effect, can meet the requirements of film thickness and glossiness.
