PAINT CIRCULATING SYSTEM AND METHOD

摘要

A paint circulating system is suitable for providing paint to applicators in a
product finishing facility. The system includes a pump (22) for pumping paint
around the system and a back-pressure regulator (BPR (25) , which
substantially eliminates pressure fluctuations of paint in the system upstream
of the BPR (25) . Control means (26) are provided for controlling the pump
(22) and the BPR (25) to operate in one of a flow mode, wherein a required
flow rate of paint around the system is maintained, and a pressure mode,
wherein a pressure of paint between the pump (22) and the BPR (25) is
maintained . The paint circulating method includes switching operation of the
pump and the BPR between the flow mode and the pressure mode.
