Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer Lackieranlage zum elektrostatischen Lackieren, bei dem der Lack durch einen unter Hochspannung stehenden betriebsseitigen Teil (10) der Anlage elektrostatisch aufgeladen und dann auf ein geerdetes Lackiergut aufgebracht wird, das dadurch gekennzeichnet ist, dass der Lack von einem vorratsseitigen Teil (1) der Anlage einem ein gasförmiges Medium enthaltenden Zwischenreservoir (18) im betriebsseitigen Teil (10) der Anlage zugeführt wird, das dabei nicht entlüftet wird, so dass das gasförmige Medium komprimiert und dabei ein Förderdruck aufgebaut wird, und dass der Lack durch den so gebildeten Förderdruck nach der elektrostatischen Trennung von betriebsseitigem Teil (10) und vorratsseitigem Teil (1) auf das geerdete Lackiergut aufgebracht wird.

Figure 00000001
The invention relates to a method for operating a painting system for electrostatic painting, in which the paint is electrostatically charged by a high-voltage operating part (10) of the system and is then applied to a grounded item of paint, which is characterized in that the paint is coated by a supply-side part (1) of the system is fed to an intermediate reservoir (18) containing a gaseous medium in the operating part (10) of the system, which is not vented, so that the gaseous medium is compressed and a delivery pressure is built up, and that the lacquer by the delivery pressure thus formed after the electrostatic separation of the operational part (10) and the supply-side part (1) is applied to the grounded paint.
