Electrostatic rotary projector for coating product, spraying installation comprising such a projector and coating method using such a projector

摘要

An electrostatic rotary atomizer of a coated article comprises a spraying cup, a body 102 and a drive turbine assembled to the body and configured to rotate the spraying cup about an axis of rotation A100 defined by the body. The atomizer includes an electrode 140 for charging the coated product sprayed by the atomizing cup, and a skirt 123 for discharging air around the cup, the electrodes are assembled to a ring 160 attached to the body . An annular slit 232 to which pressurized air is supplied by the pressurized air flow circuit F3 is formed radially between the ring 160 and the skirt 124, its outlet 234 being the atomizer's oriented towards the front.
