DESCRIPTION

The Oil Intensifier System (OIS) is intended to generate
pressure up to 500 MPa (75 000 psi) using an OPG1 or
MP G1 (whose maximum pressure is 200 MPa (30 000 psi)).
The OIS includes a 5:1 intensifier. The intensifier is used
only when necessary to generate pressure > 200 MPa
(30 000 psi).

Rupture Disc and Muffler

Operation: Using Intensifier (Pressure > 200 MPa
(30 000 psi))

OPG1 or MPG1 generates and adjusts pressure up to
200 MPa (30 000 psi). Generally, the OIS intensifier is

used only when running tests that include pressures
greater than 200 MPa (30 000 psi). The OIS may be

switched into and out of use under pressure.

INSTALLATION

n Position the OIS between the OPG1 or MPG1 and

the PG7302 with the PG7302 to the left.

o Using a DH500 coned and threaded tube, connect

the OPG1 or MPG1 TEST port to the OIS SUPPLY
port (1).

p Using a DH500 coned and threaded tube or two

tubes and a tee, connect the PG7302 TEST port to
the OIS lateral TEST port (2).

Operation: Intensifier Not in Use (Pressure
≤ 200 MPa (30 000 psi))

n Open LOW PRESSURE SHUTOFF valve (4) and close

INTENSIFIER SHUTOFF valve (5). In this condition,
OPG1 or MPG1 generates pressure straight through
the Intensifier System, by passing the intensifier.

o Plug TEST port (6) if it is not being used.

n When running tests that include pressures above

200 MPa (30 000 psi), connect the device under test
(DUT) to the upper TEST connection (6) of the OIS.

o Set pressures under 100 MPa (15 000 psi) using the

OPG1 or MPG1, without the intensifier.

p To switch in the intensifier, first close the LOW

PRESSURE SHUTOFF valve (4), then open the
INTENSIFIER SHUTOFF valve (5). In this condition the
OPG1 or MPG1 pressure is shut off from the PG7302
and is applied to the low side of the intensifier.
Increasing pressure on the low side of the intensifier
results in pressure changes five times greater on the
high side (PG7302 side) of the intensifier.

q Use the OPG1 or MPG1 to generate and adjust

pres sure as necessary to set test points and float the
PG7302 piston.

r Before switching out the intensifier, be sure that the

to Start Position

r Open the INTENSIFIER SHUTOFF valve (5).

If the intensifier runs out of stroke towards the high side,
adjusting the pressure on the intensifier's low side no longer
affects the pressure on the high side. This procedure allows
the intensifier pistons to be returned to their start position. It
is only necessary to use this procedure if the intensifier
pistons have become positioned near the end of stroke and
cannot be returned naturally by the high pressure.

The Oil Intensifier System is equipped with a pressure rupture disc on its low pressure circuit. (See schematic

reference 7). The disc ruptures permanently at 120 MPa (17 500 psi). Once ruptured, the disc must be replaced.

If pressure on the high side of the intensifier returns

to zero when the INTENSIFIER SHUTOFF valve is
opened, the intensifier is not at the start position.
Repeat the process until the high side of the
intensifier holds pressure.
