Abstract
A paint circulating can include: a pump for pumping paint around the system; an automatically adjustable back-pressure regulator (BPR) to reduce pressure fluctuations of paint upstream of the BPR; means for indicating a flow rate of paint through a conduit upstream of the BPR; and control means for controlling the BPR to maintain a desired flow rate based on the indicated flow rate.
Claims13
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;
- an automatically adjustable back-pressure regulator (BPR) to reduce pressure fluctuations of paint upstream of the BPR;
- means for indicating a flow rate of paint through a conduit upstream of the BPR comprising means for measuring a pressure drop in the paint flow along a length of a section of the conduit, wherein the means for measuring a pressure drop in the paint comprises pressure sensors configured to measure a starting pressure of paint at the start of the section of the conduit, and an ending pressure of paint at the end of the section of the conduit;
- and
- control means for adjusting a setting of the BPR to maintain a desired flow rate based on the indicated flow rate.
