5.0 PREVENTIVE
MAINTENANCE
WARNING
Failure to wear approved respirators and eye
protection when servicing dust-laden areas of
the cabinet and dust collector, and when
emptying the dust bag or collector could result
in serious eye irritation and lung disease or
death. Toxicity and health risk vary with type of
media and dust generated by blasting. The
respirator must be approved for the type of dust
generated. Identify all material being removed
by blasting, and obtain a material safety data
sheet for the blast media.
NOTE: To avoid unscheduled downtime, establish a
weekly inspection schedule. Inspect all parts subjected
to media contact, including; the gun, nozzle, media hose,
flex hose, and wearplate, plus all items covered in this
section.
5.1.
BNP Gun Assembly
5.1.1
Inspect the BNP gun for wear. Inspection and
replacement of the air jet cover before it wears through
will prolong the life of the jet.
5.2 Dust
Bag
5.2.1
The bag collects dust on its inner surface. A high
dust level in the cabinet indicates a dirty bag. Empty as
frequently as necessary to maintain visibility in the
cabinet, and before the weight of dust prevents full
inflation of the bag. A zipper opening is located in the
bottom of the bag for emptying. NOTE: Poor visibility
and frequent emptying of the bag could indicate the
need to upgrade to a dry filter dust collector.
5.3
Dry Filter Dust Collector
5.3.1
The dry filter uses tubular filters, which collect
dust on their inner surfaces. A shaker arm accessible
from the outside of the collector is used to shake dust
from the filters. Every two hours, turn off the exhauster
and shake the filters vigorously.
CAUTION
Do not shake the filters when the exhauster is
on, doing so will accelerate wear on the filters
around the shaker assembly, but not shake the
dust loose.
5.3.2
Empty the dust collector drawer regularly. Begin
by checking the drawer daily and adjust frequency based
on usage and breakdown rate of media. Dump the
contents into a suitable disposal container.
CAUTION
Do not open the dust drawer door while the
exhauster is on. The drawer chamber is under
positive pressure when the exhauster is on.
Opening the dust door while the exhauster is
operating or the paddle wheel rotating, will
allow dust to escape.
NOTE: Blast media is usually non-toxic, however, some
materials removed by the process may be toxic.
Do not
use the INEX cabinet for blasting toxic materials.
Use cabinets with reverse pulse dust collectors and
HEPA filters for those applications.
5.4 View
Window
Cover
Lens
5.4.1
Rapid frosting of the view window can be
avoided by directing ricocheting media away from the
window, and by installing a cover lens on the inside
surface of the window. Using cover lenses prolongs the
life of the view window.
5.4.2
To install a cover lens, remove the adhesive
backing and apply the lens to the clean, dry, inner
surface of the view window. When the cover lens
becomes pitted or frosted, peel it off and replace it.
5.5 Reclaimer
Debris
Screen
5.5.1
The screen is accessible through the reclaimer
door. With the exhauster off, remove the screen and
empty it daily or when loading media. Empty the screen
more often if part blasted causes excessive debris. Do
not operate the machine without the screen in place.
5.6 Air
Filter
5.6.1
The cabinet is equipped with a manual drain air
filter. Drain the filter at least once a day, and more often
if water is present. Moist air inhibits the flow of media. If
moisture continues to be a problem, a dryer or after
cooler may be required in the air supply line.
5.7 Media
Hose
5.7.1
To avoid unscheduled down-time, periodically
inspect the media hose for thin spots, by pinching it
every 6 to 12 inches. Replace the hose when it becomes
soft.
