schedule for your Horizon powder coating system.
Table 5-1 Daily Maintenence
Equipment Procedure
Accumulators and Vent Hoses
Vacuum out the accumulators and blow the powder out of the
vent hoses with compressed air.
Air Dryers
Refer to your air dryer manual for maintenance procedures and
schedules.
Air Velocity
Measure the air velocity at all booth openings with a velometer.
Minimum velocity is 30 m/min (100 fpm).
Compressed Air Supply NOTE:
The air dryer should remain on at all times to prevent
moisture from accumulating in the compressed air system.
Hold a clean, white cloth under the drop leg and open the
drop-leg drain valve. Water, oil, or other contaminants will stain
the cloth. Eliminate any source of contamination. Drain the
filters and separators and check the filter elements. Check all air
pressure regulator settings.
Fan Section
Remove the final filters and inspect the fan compartment.
Vacuum out any powder. If significant amounts of powder have
accumulated in the fan compartment, the cartridge filters may be
leaking. Refer to the Troubleshooting section for instructions.
Inspect the V-belts. Replace cracked or worn belts.
Filters
Check the final-filter differential pressure gauge. It should read
between 1 and 2.5 inches of water (wc). Make sure no powder is
leaking from around the filter gaskets or through the face.
Check the cartridge-filter differential pressure gauge. It should
read between 4 and 6 inches of water (wc). Check the pulse
valve timing.
Flame Detector System
Check the detector sensors every four hours and clean the
lenses, if necessary. Make sure air is being supplied to the
sensors. Make sure the detector system is operating properly.
Gun Movers (Oscillators and
Reciprocators)
Each shift, make sure the gun movers are stroking smoothly and
at the proper speed. Make repairs and adjustments if necessary.
Lubricate the gun movers as described in their manuals.
Powder Guns
Disassemble and clean the spray guns according to the
instructions in their manuals.
Powder Pumps
Disassemble and clean the pumps according to the instructions
in their manuals. Replace worn parts.
Rotary Sieves
Empty the scrap pail.
Open the sieve housing and clean the rotor and screen with a
soft brush. Replace the screen if it is damaged.
Check the bearing air pressure and flow rate. Check the
vent-assist air pressure. Refer to your sieve manual for more
information.
