User manual DHI OIL INTENSIFIER SYSTEM FOR OPG1 AND PG7302

[. . . ] Oil Intensifier System for OPG1 and PG7302 P/N 401746 Instruction Sheet 1. 3. SUPPLY connection to OPG1 TEST Port (DH500) TEST connection to PG7302 (DH500) Intensifier 4. [. . . ] 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 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. Use the OPG1 to generate and adjust pressure as necessary to set test points and float the PG7302 piston. 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 INSTALLATION Position the OIS between the OPG1 and the PG7302 with the OPG1 to the right and the PG7302 to the left. Using a DH500 coned and threaded tube, connect the OPG1 lateral TEST port to the OIS's SUPPLY port (1). Using a DH500 coned and threaded tube or two tubes and a tee, connect the PG302 TEST port to the OIS's lateral TEST port (2). Operation: Intensifier Not In Use (Pressure < 200 MPa (30 000 psi)) Open LOW PRESSURE SHUTOFF valve (4) and close INTENSIFIER SHUTOFF valve (5). In this condition, OPG1 generates pressure straight through the Intensifier System, bypassing the intensifier. Plug TEST port (6) if it is not being used. pressure as it was switched in so that its pistons are back to the 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.
