Patent ID: 7934466

Claim:
A coating installation for the coating of construction units with a coating medium, comprising: a dosing pump configured to supply a predetermined quantity of the coating medium to an application device configured to apply the coating medium; a pressure regulator disposed upstream of the dosing pump, the pressure regulator configured to set a desired coating medium pressure at an input of the dosing pump; a first pressure sensor configured to measure a first coating medium pressure downstream of the dosing pump; a second pressure sensor configured to measure a second coating medium pressure upstream of the dosing pump; a control unit configured to control the pressure regulator to set a desired pressure difference across the dosing pump independent of the predetermined quantity conveyed by the dosing pump, wherein the control unit is configured to control the pressure regulator as a function of at least the first coating medium pressure and a feedback of a measured pressure difference across the dosing pump, such that the measured pressure difference across the dosing pump assumes the desired pressure difference, wherein the desired pressure difference across the dosing pump is substantially constant and in the range between 0.5 bars and 1.5 bars; and an adaptation unit in communication with the two pressure sensors, the adaptation unit configured to adjust the control unit as a function of at least the first coating medium pressure and the second coating medium pressure.
