ABSTRACT:
A rotary type electrostatic spray painting device comprising a rotary shaft supported by static pressure air bearings in a non-contact state. A drive turbine wheel and a braking turbine wheel are fixed to the rotary shaft. A paint injection nozzle is provided for feeding paint onto a cup shaped inner wall of the spray head. The paint injection nozzle is connected to a paint suction device. When changing the color of the paint, pressurized air is injected towards the braking turbine wheel and, at the same time, paint remaining in the paint injection nozzle is sucked away by the paint suction device.
