OPG1TM Operation and Maintenance Manual High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases can be released unexpectedly and with extreme force. High pressure systems should be assembled and operated only by personnel who have been instructed in proper safety practices. © 2000 DH Instruments, Inc.

[. . . ] The other end of the plunger is connected to a dome loaded pneumatic actuator. Changing the pneumatic pressure on the dome loaded actuator causes the plunger to move, increasing or decreasing oil pressure. A spring returns the plunger to its minimum stroke position when there is no pressure on it. A mechanical system tracks movement of the plunger and an indicator (17) displays the plunger position on the front panel. The PDVV (+) valves (12) and PDVV (-) valves (11) are momentary, poppet valves that open when pressed. The (+) valves (12) admit drive air pressure to the PDVV actuator causing the PDVV piston to move forward compressing the oil and increasing the pressure. The (-) valves (11) have the opposite effect causing pressure to decrease. Page 19 ©2000 DH Instruments, Inc. OPG1TM Operation and Maintenance Manual 20 21 1. 10.

Front Panel 3. 2. 1 SETTING INLET PRESSURE, DRIVE SET REGULATOR ADJUSTMENT Numerical references in this section refer to Section 3. 2, Figure 6. The DRIVE SET regulator (4) is a self venting regulator that sets the pneumatic drive pressure to the hydropneumatic pump. This determines the oil pressure that the pump will generate before stalling and that is available on demand when the INLET valve (5) is opened. The PUMP DRIVE gauge (3) indicates the pump drive pressure on its inner dial and the corresponding pump output oil pressure on its outer dial (BLUE numbers). Use the outer BLUE indication to predict the maximum pressure that will be generated when the inlet valve is opened. Page 21 ©2000 DH Instruments, Inc. OPG1TM Operation and Maintenance Manual With the INLET valve (5) closed, use the DRIVE SET regulator (4) and the PUMP DRIVE gauge (3) indication to set the desired maximum pump output pressure. This is generally done at the beginning of a test or calibration based on the maximum pressure of the calibration. It is good practice to set the pump output pressure below the maximum pressure desired to avoid accidental overpressure. The PDVV can then be used for the final pressure adjustment at the maximum pressure (see Section 3. 2. 3). The DRIVE SET regulator sets the oil pressure output of the hydropneumatic pump. When the INLET valve is opened, this pressure can be generated very rapidly in the system connected to OPG1.
