What Is A Paint Circulating System

A pressurized vessel used to transport material to various locations. More efficient then manual moving material to individual locations.

What Are We Doing?

• Moving material from point A to point B.• Supply material fluid pressure.• Supply material fluid flow.• Maintain material integrity.

That is all we do!

Sounds simple doesn’t it?

What Are We Doing?

Point A Point B

5

• The martial that is used for painting the vehicles is a solvent borne material which is extremely flammable. The paint is stored and pumped from a paint mix room.

• MIX ROOMS ARE CLASS 1 DIVISION 1 AREAS – NO ELECTRIC ITEMS ARE ALLOWED IN THIS ROOM INCLUDING – (CELL PHONES, FLASH LIGHTS, RADIOS, ETC). UNLESS APPROVED BY FORD SAFETY

• The paint is pumped from the paint circulation module to the spray booths in what is called a header system. The headers system is constructed from stainless steel pipe/tubing and delivers paint to each robot or manual spray station.

• At each robot or manual station, a line tee’s off the header to feed this station. This is called a drop/paint station.

• The paint must be applied to the vehicle at the correct temperature. A paint heat exchanger system is used to maintain a temperature of +/- 2 degrees F

Recirculation of the header

and drop legs are very

important

Utilize (1) Pump for Recirculation and (1) Pump for Empting of the Tank

Special Cage Inside Tank to Capture 2K Waste Debris From Clogging Pumps

Special Waste Collection Funnel Under Cap Cleaner to Flush Drop Legs and Prevent Debris from Entering Waste Header

Note: Containment Pan Not Shown

Ball Valves Added to Header to Have the Ability to Power Flush Header for Preventative Maintenance

Gravity Waste Header Fabricated from 2” S.S. Tubing Utilizing Sanitary Fittings for Smooth ID and Ease of Maintenance. Line Installed at ¼” – 3/8” per foot to maintain proper drain velocity

Purge Solvent Piped to Tank so

Virgin Solvent Can be Added for

Cleaning. A Catalyst Stop can be Substituted to

Prevent the Catalyst from Curing (paint supplier can recommend

material)

WASTE COLLECTION SYSTEM• Each time the robot or manual station changes color a certain amount of waste is generated.

This waste is collected at the paint booth in a waste collection system.
