Before switching out the intensifier, be sure that the

PG7302 piston is fully down (LSTOP) as the pressure

may change abruptly during the switching procedure.

If possible, switch out the intensifier at the same

pressure as it was switched in so that its pistons are

back to the start position. To switch out the

intensifier, first close the INTENSIFIER SHUTOFF

valve (5) and then open the LOW PRESSURE

SHUTOFF valve (4).

Operation: Returning the Intensifier Pistons

to Start Position

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.

Close the LOW PRESSURE SHUTOFF valve (4).

Open the OPG1 or MPG1 EXHAUST valve.

Open the INTENSIFIER SHUTOFF valve (5).

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.
