The abrasive ball valve is
closed.
See
Setting Up the Equipment, page 13
The abrasive metering valve
is not properly set.
See
Setting Up the Equipment, page 13
The pot does not have a
sufficient amount of abrasive.
See
Refilling the Pot with Abrasive, page 20
.
The pinch valve does not
open.
Engage the blast control switch (B) and check for actuation
of the pinch valve. If there is no actuation, check the orange
tubing for proper connection and make sure there are no
obstructions in the tube. If the tube connection is satisfactory,
inspect the mufflers on the 4-way valve for debris. If debris
present, clean or replace the 4-way valve. Clean or replace
the control box (P) air filter.
There is an obstruction inside
the pot or inside the abrasive
hose between the pot and the
enclosure.
Follow
, followed by the
Pressure Relief Procedure, page 10
. With the abrasive
hose disconnected, inspect the interior of the pinch hose
for obstructions or debris and replace if necessary (see
Replacing the Pinch Hose, page 32
). Remove the tri-clamp
from the bottom of the pot. Inspect the bottom of the pot and
the abrasive hose for obstructions or debris.
The pot pressure is too low.
With the blast control disengaged, allow the pot to pressurize
and wait for the pump to stall. If the pot pressure gauge does
not reach 185 psi (12.75 bar, 1.275 MPa), see the “Unable to
fill or pressurize the pot with water” problem listed in this table.
While in BLAST mode,
with the blast control
switch (B) engaged,
air is flowing from the
nozzle but little or no
abrasive is flowing from
the nozzle.
The blast pressure is too high.
If the blast pressure gauge reads 160 psi (11.03 bar, 1.10
MPa) or greater, it may not be possible to achieve greater
than 15 CPM on the MediaTrak. This is more common with
fine mesh abrasive usage. Decrease the blast pressure to
100 psi (6.9 bar, 0.69 MPa) to see if CPM can be increased.
