Smart Circulation System in Paint Circulating Systems
SUMMARY :
?Paint circulating systems are used to transport paint from material tanks to applicators.
?They are designed to supply pressure, flow and material integrity “at the applicator”.
?On average Automotive OEMs will have 12 basecoat colours circulating in independent lines.
?On average a single colour will only be in use “at the applicator” 2 hours a day if the plant is running 3 shifts, 1.33 hours for 2 shifts and 0.66 hours for 1 shift.
?The paint is maintained at “spray pressures” 24 hours a day even though material is not required “at the applicator”.
?High flow rates may also be maintained 24 hours a day.
FACTS IN DETAILS:
Recent studies have shown that on average a single color will only be in use “at the applicator” 2 hours a day if the plant is running 3 shifts, 1.33 hours for 2 shifts and 0.66 hours for 1 shift. The paint is maintained at “spray pressures” 24 hours a day even though material is not required “at the applicator”.
“Smart Circulation” Control reduces paint shear and energy by lowering the system pressure and flow rate when the paint color is not in demand. “Smart Circulation” Control automatically adjust system pressure and flow depending on the needs “at the applicator”.
This provides:
? Lower energy use (35% to 90% reduction).
? Lower paint shear.
? Lower pump and system component wear
A pneumatically operated back pressure regulator can be energized (production mode) or de-energized (sleep mode) depending on if that specific color is required at the spray booth.
At the same time the BPR is being put in sleep mode, the electrically controlled paint pump VFD is adjusted to decrease flow. The end result of implementing “Smart Circulation” Control has proven to add months of shelf life for our low volume paint and reduced system energy cost from 38% til 90%.
Smart Pump… every Hz equals flow!
Smart BPR… can be automatically energized or de-energized!
End Result…
“SMART CIRCULATING SYSTEM"
Existing circulating systems maintain operating pressure 24 hours a day even though material is not in demand…
SMART CIRC automatically adjusts system pressure and flow to meet the demands at the applicator!
