Supply device for a painting installation

摘要

The delivery system for especially paint in a paint shop has a pump (3) to deliver the paint, a pipe (2) connected to the pump for transmission of the paint, and a regulator (4) and/or a controller to adjust the output capacity of the pump in conformance with a predetermined set value (Q soll). The regulator or controller has a predetermined over-control characteristic (K d), and an adaptation unit (7) is provided for adapting to the over-control characteristic. A pressure sensor is installed downstream behind the pump and to it is connected the adaptation unit on the inlet side. An independent claim is included for a method of operating a delivery system for especially paint in which an over-control characteristic is automatically adapted to the viscosity of the paint to save making a manual input.
