摘要： An adapter for converting spray guns to electrostatic or induction charging includes a housing (60) mountable on a spray gun (10). A high voltage power source (70) is contained in the housing (60) and is connected to an electrode assembly (120) mounted on the front of the housing (60). The electrode assembly (120) includes four electrodes (154, 156, 154', 156') which extend in front of the spray gun nozzle (27) and air cap (42) and are spaced symmetrically around the spray axis (158). The nozzle (27) is electrically grounded, while the electrodes (154, 156, 154', 156') carry a voltage in the range of 3-15kV, to produce in the spray path from the nozzle (27) an electrostatic field which produces electrical charges on the sprayed particles. When conductive liquids are sprayed, the particles are charged by induction at relatively low electrostatic field gradients, while nonconductive liquids require high electrostatic field gradients which produce corona effects. These corona effects are enhanced by the provision of a corona needle (190) mounted on the nozzle (27) at the spray axis (158).

摘要： Induction charging apparatus for HVLP spray guns includes an air cap (70) having a central fluid exit orifice (94) for receiving the spray gun nozzle (80). The cap (70) includes one or more charging electrodes (110, 112) surrounding the orifice (94) and carrying a voltage sufficiently large to induce on the spray droplets charges of a polarity opposite to that on the electrodes (110, 112). The cap includes a rotatable electric connector (126, 128, 130) to enable the cap to rotate 360 DEG while maintaining electrical connections between the electrodes (110, 112) and a power supply (356).
