How to use HDA-90 automatic electrostatic spray gun?

HDA-90 Automatic Electrostatic Spray Gun Usage Steps

Preparation work

Check connections: Ensure that all pipelines (air pipes, paint pipes, high-voltage cables) of the spray gun are securely connected and undamaged.

Grounding: Reliable connection of the ground wire of the electrostatic generator to the grounding terminal is crucial for safe operation.

Paint preparation: Insert the suction pipe of the oil pump into the prepared paint bucket and close the return pipe.

Parameter settings

Pressure regulation: Turn on the oil pump and adjust the pressure to approximately 3MPa. Then, open the air pressure valve of the electrostatic generator and adjust the total air pressure to 6MPa. During the spraying process, if you feel that the air pressure is too high, you can make slight adjustments by using the blue adjustment knob on the side of the spray gun.

Voltage regulation: Turn on the power of the electrostatic generator and adjust the output voltage to 60kV.

Spray operation

Start spraying: After confirming that the air pressure, voltage, and paint supply are normal, pull the trigger of the spray gun and start spraying.

Maintain distance: According to the process requirements, maintain a spraying distance of about 300mm between the spray gun and the surface of the workpiece.

Uniform movement: Move the spray gun at a stable speed and trajectory to ensure uniform coating.

End of work

Shut down the system: After the spraying is completed, first turn off the paint supply, then turn off the air source, and finally turn off the power of the electrostatic generator.

Cleaning and maintenance: Clean the spray gun in a timely manner to prevent the paint from drying up and blocking.
