16.0. PRESSURE ADJUSTMENT PROCEDURE:
This procedure is to be used to adjust the output pressure of the ChipBLASTER high-pressure unit.
Please be aware that you must have working knowledge of the complete ChipBLASTER system
before making any pressure adjustments
. All ChipBLASTER units are shipped out of the factory
pre-set at a working pressure of 69 Bar (1000 psi), unless otherwise specified by the end user. This
pressure can be read from the high pressure gauge located on the top of the ChipBLASTER unit.
Check the machine tool specifications for a maximum operating pressure before proceeding with
this procedure.
DO NOT EXCEED THE MANUFACTURERS MAXIMUM OPERATING
PRESSURE
.
Procedure:
16.0.1. Locate the regulator on the manifold assembly
under the ChipBLASTER’s electrical
enclosure. The regulator will need to be accessible during this procedure for
achieving settings over 69 Bar (1000 psi).
16.0.2.
Regulator adjustment: The regulator is used to regulate the pressure to the
machining center from over pressure.
16.0.3.
Loosen locking nut using a ¾” wrench.
16.0.4. Turning the adjustment screw in using a 3/16” hex head wrench (clockwise)
increases the regulator setting.
16.0.4.
Turning the adjustment screw out (counter clockwise) decreases the regulator
setting.
16.0.5.
After setting the regulator, tighten the locking nut.
USE EXTREME CAUTION WHEN WORKING ON LIVE EQUIPMENT.
If you cannot achieve the desired output pressure, please check to be sure that the unloader has been
properly set. Also refer to the orifice reference chart (SECTION 28) included in this manual to verify
nozzle size to make sure you are within the machine’s capabilities.
69 Bar (1000 PSI) at 27.4 l/min (7.25GPM):
Factory setting is with a #55 (0.080” [2 mm] dia.) nozzle to achieve 69 Bar (1000 psi)
