Abstract
A method for mixing at least two liquid components of a two- or multi-component wet coating system, wherein a feed component under a first hydraulic pressure set at constant is fed discontinuously through a variable passage cross-section to a parent component under a second hydraulic pressure set at constant. An actual feed quantity of the feed component is detected and the feed quantity of the feed component is regulated with respect to a target feed quantity for the feed component in such a way that a timing cycle of the discontinuous feed and the passage cross-section for the feed component are influenced.
Claims13
A method for mixing at least two liquid components in a multi-component wet coating system, said method comprising:
- discontinuously feeding a feed component under a first hydraulic pressure set at constant through a variable passage cross-section to a parent component under a second hydraulic pressure set at constant;
- detecting an actual feed quantity of the feed component;
- and
- regulating the actual feed quantity of the feed component with respect to a target feed quantity for the feed component in such a way that a timing cycle of the discontinuous feeding and the variable passage cross-section for the feed component are influenced.
A device for mixing at least two liquid components in a multi-component wet coating system, the device comprising:
- a line system for the separate feeding of the at least two liquid components under hydraulic pressure, wherein the line system comprises a parent line for a parent component or a parent component mixture and a feed line emerging into the parent line for a feed component;
- an on/off timing valve for closing or opening the feed line and for the discontinuous feed of the feed component;
- a throttle device for changing a passage cross-section of the feed line;
- a flow quantity meter for detecting an actual flow quantity of the feed component;
- and
- a control of the actual flow quantity of the feed component comprising an actuator which actuates the throttle device and the control controls both the actuator and the on/off timing valve in such a way that the passage cross-section of the feed line and a timing cycle of the discontinuous feed are influenced for the control-based change of the actual flow quantity.
