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.

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. Use caution in setting the pump drive pressure and always check the setting and adjust if necessary before using the INLET valve (see Sections 2. 4. 2 and 3. 2. 1). 3. 2. 2 ROUGH PRESSURE GENERATION/CONTROL, INLET AND OUTLET VALVE OPERATION Numerical references in this section refer to Section 3. 2, Figure 6. The INLET valve (5) and OUTLET valve (8) are high pressure needle valves. Their operation is highly progressive over a half-turn with mechanical stops at each end so they cannot be overtightened. The valve is turned CW to close and CCW to open. A WHITE dot on the handle body indicates its current open/close position. The INLET valve (5) controls the flow of oil from the hydropneumatic pump into the test system. When the INLET valve is closed, the pump is shut off from the test system and dead ended. When the INLET valve is open, the pump output is connected to the test system and can fill and generate pressure into the system. The OUTLET valve (8) controls the flow of oil from the test system back to the tank.
