Ransburg Aerobell (Std.) Rotary Atomizer A12381 - Manual (Page 43)

6. Clean the exterior of the Aerobell as follows
(read following "Warning" first):
>
To reduce the risk of fire or explosion,
OSHA and NFPA-33 require that solvents
used for exterior cleaning be non-flamma-
ble (flash points higher than 100 o F/37.8 o C).
Also, since electrostatic equipment is
involved, these solvents should also be
non-polar. Examples of non-flammable,
non-polar solvents for wipe down are: amyl
acetate, methyl amylacetate, high flash
naptha, and mineral spirits.
a. If using a rag to hand wipe the Aerobell,
turbine air should be off, but leave shaping
air on. Be careful not to drip solvent into the
opening behind the bell (see step #1).
b. Do not use conductive solvents such as
MEK to clean the Aerobell.
7. Do not reuse an atomizer bell that shows signs
of damage such as nicks, heavy scratches, dents,
or excessive wear.
8. Periodic cleaning of the slots in the shaping air
ring will prevent paint build-up which does affect
pattern control or cause defects in parts being
coated. Follow "Cleaning Shaping Air Slots and
Annulus" in the "Maintenance" section and clean
the slots of the shaping air ring using a soft bristle
brush.
To prevent paint build-up in slots of shaping air
ring while installed, clean shroud assembly with
shaping air ON. Clean with a damp rag or soft
bristle brush. Do not soak or saturate area to
force fluid or paint into the slots (70-100 SLPM
of shaping air is recommended).
3. Flushing should be done with the atomizer
bell cup installed. The bell cup will normally be
fully cleaned with flushing. However, if there is
any remaining paint build up on any areas of the
bell after flushing, the bell should be removed for
hand cleaning.
4. Clean the bell cup by soaking in an appropriate
solvent as long as necessary to loosen paint. Use
a soft bristle brush dipped in solvent to remove
paint. Make sure all signs of paint are removed
(See the following "Caution"). Rinse and dry bell.
Using a non-metallic item (toothpick), clean the
center holes of the splash plate. Using plenty of
cleaning fluid, flush these holes towards rear of
bell cup. Make sure these holes are clean.
5. Before reinstalling the bell onto the shaft, check
the tapered mating surfaces of the turbine shaft
and bell for any paint residue. Clean any residue.
See following "Caution".
W A R N I N G !
>
Using an atomizer bell with paint build-
up will cause a bell imbalance. An im-
bal-anced bell may cause bearing damage
and turbine failure. Also, any paint residue
caught between the tapered surfaces can
prevent the bell from seating properly and
result in an imbalanced condition.
