see section
6.2
Troubleshooting the
Pneumatic Control Circuit
.
Problem:
Poor production rate.
Probable Cause
Remedy
Low blast air pressure.
Increase pressure within the specified
range.
Nozzle too small (the
smaller the nozzle, the
smaller the blast pattern).
Install a larger nozzle (and air jet on
suction systems) to accommodate
your production needs.
Improper media.
See section
4.1
Media Selection and
Use.
Improper media flow.
See section
3.0 Equipment
Adjustments.
Low media level.
Add media to maintain recommended
level.
Parts to be blasted are oily
or wet.
Parts to be processed must be
absolutely dry and free of oil, grease,
etc.
Media has high dust
content (Blast media
breaks down and must be
replaced on a regular
basis).
Remove old media from system and
replace with new. Adjust reclaimer
tuning band. See section
3.3
Equipment Adjustments.
Problem:
Static charge build-up and discharge irritates the operator.
Probable Cause
Remedy
Low quality blast hose
(poor conductor of static
charge).
Replace blast hose with one of high
quality. Static charges are created
and build up by the air and media
moving at high velocity through the
blast hose.
System grounded
improperly.
Earth ground the system.
Part insulated, resting on
rubber mat.
Place part on metal surface, i.e.
cabinet floor or turntable top.
Low compressed air and
ambient humidity.
Install Empire Anti Static Strap, part
510411.
Problem:
There is blast air flow, but intermittent or no media flow.
Probable Cause
Remedy
Blast air pressure too low. Adjust and maintain pressure within
recommended range.
Clogged nozzle.
Disassemble and clean nozzle.
