BOOSTER HIGH PRESSURE INSTRUMENT GAS
SUPPPLY CONNECTION
To connect the booster high pressure instrument gas supply, follow the
steps below:
n
Connect a high pressure gas supply to the gas booster high pressure
IN port
. The
IN port
is a 1/4 in. NPT F fitting on the high pressure
gas filter. Use a thread sealer to seal the connection. The high pressure
gas supply should not exceed 200 MPa (3 000 psi). See Section 2.2.2.2 for
additional information on high pressure gas supply requirements.
Pressure present at the High Pressure IN port will be present at the high
pressure OUT port. Do not supply pressure to the high pressure IN port unless you
are prepared for there to be pressure at the high pressure OUT port.
2.3.2.4
BOOSTER HIGH PRESSURE OUTPUT CONNECTION
The booster high pressure
OUT port
is usually connected to the high pressure
inlet of a test or calibration system to which high pressure is to be supplied, such
as the
DHI
GPC1 Gas Pressure Controller. The booster high pressure
OUT port
is connected to the
SUPPLY port
of the GPC1 (see the GPC1 Operation and
Maintenance Manual).
To connect the booster high pressure
OUT port,
proceed as follows:
-
Connect the 1.5 m, 1/8 in. nipple with DH500 tips between the
HIGH
PRESSURE OUT
port and the GPC1
SUPPLY
port. The DH500 glands and
collars are delivered installed in the female ports. Remove the orange plastic
plug, slip the gland onto the DH500 tip, install the collar onto the DH500 tip and
thread the gland into the female DH500 fitting. Torque gland to 15 Nm (11 lb ft).
Do not bend tubing with radius less than 50 mm (2 in.) or pressure capacity
may be reduced.
Depending on the drive pressure set by the DRIVE ADJUST regulator, GB-75 may
generate pressure over 70 MPa (10 000 psi) and GB-152 may generate pressure over
110 MPa (16 000 psi). Be sure to use fittings and tubing rated for the pressure that
is to be output from the booster. Always use a DH500 or equivalent tube on the
DH500 F high pressure OUT port connection. To limit the maximum pressure that
can be generated by the booster, limit the drive air supply to the Drive Air Control Kit
(see Section 2.2.2.1).
