Electrostatic coating apparatus for conductive paint.

摘要

An electrostatic coating apparatus (1) for coating an electroconductive paint comprises an electrostatic coating machine applied with a high voltage, a paint supply pipeline (10) for supplying an electroconductive paint and a reciprocal pump (3) disposed between the electrostatic coating machine and the paint supply pipeline and adapted such that the paint introduced from the input port (4) is discharged at a predetermined flow rate from the output port (5) of the pump (3) and supplied at a predetermined amount to the electrostatic coating machine (1), and the input port (4) of the pump is made detachable from the paint supply pipeline. Electric insulation to paint supply pipelines can be saved. The reciprocal pump (3) may be replaced with a paint charge pipe connected with a cleaning liquid supply pipe for supplying a cleaning liquid at a predetermined flow rate, thereby discharging the paint from the paint charge pipe.
