Abstract
An installation particularly suited to use in the automobile industry for electrostatic application of conductive coating product is partly at a high-tension voltage and partly grounded, these parts being separated by at least one temporary insulating device. The electrostatic sprayer is fed from a first storage tank insulated from ground and the latter is filled in a very short time period with coating product previously stored in a grounded second storage tank, through a temporary insulating device.
Claims11
Installation for electrostatic application of relatively conductive coating product comprising at least one electrostatic sprayer connected to a variable or interruptible high-tension voltage supply, a first storage tank at said high-tension voltage, connected to feed said sprayer and means for filling said first storage tank including parts electrically grounded separated from said first storage tank by at least one pipe member forming a temporary insulating device, said filling means comprising a grounded second storage tank and means for rapidly emptying said second storage tank into said first storage tank through said pipe member forming a temporary insulating device.
