Abstract:
1. A paint circulating system suitable for providing paint to applicators in a product finishing facility, the system comprising: a pump for pumping paint around the system; a back-pressure regulator operable in an activated state to substantially eliminate pressure fluctuations of paint upstream of the back-pressure regulator, and operable in a deactivated state to enable paint flow without being responsive to pressure fluctuations, wherein the applicators are configured to dispense paint when the back-pressure regulator is operating in the activated state, and wherein the applicators are configured to not dispense paint when the back-pressure regulator is operating in the deactivated state; and a controller comprising circuitry configured to provide one or more electronic control signals for controlling the pump and the back-pressure regulator to operate in one of a flow mode, wherein the back-pressure regulator is deactivated and a required flow rate of paint around the system is maintained, and a pressure mode, wherein the back-pressure regulator is activated and a pressure of paint between the pump and the back-pressure regulator is maintained.
