[. . . ] GB-K-75 and GB-K-152 Gas Booster Packages For PPCK+ Pressure Controller/Calibrator Operation and Maintenance Manual © 1998 - 2000 DH Instruments, Inc. GB-K Gas Booster Package Operation and Maintenance Manual This equipment described in this manual is designed and manufactured for the intended purpose of generating high pressure gas and regulating two independent gas output pressures. Certain precautions need to be followed during installation and operation of this device. Reading and understanding the material is essential to the safe and correct operation of the unit. Pressurized equipment is potentially dangerous. [. . . ] Should a regulator be adjusted from a higher pressure to a lower pressure, once gas begins to flow in the regulator the pressure ultimately set will be lower than that initially set. To avoid this situation, set the initial pressure below the setpoint then adjust the regulator up to the final setpoint. The Shop Drive Air Pressure Regulator (10) is constructed of 316 stainless steel and nylon wetted components. It is a self-venting type regulator with an outlet pressure control range of 0 to 0. 86 MPa (125 psig). Maximum inlet pressure is 1 MPa (50 psig). The control knob is pulled out to make adjustments; pushed in to lock into position and prevent accidental changes. It can also be pulled off for tamper resistance. The Low Pressure Outlet Regulator (12) is constructed of aluminum, Viton, stainless steel and Nylatron wetted materials. It is a non-venting type regulator with an outlet pressure control range of 0. 15 to 1. 25 MPa (20 to 180 psig). Maximum inlet pressure is 20 MPa (3 000 psig). The High Pressure Outlet Regulator (7) is constructed of 303 stainless steel, Kel-F, Buna-N, and Teflon wetted materials. It is a venting type regulator with an outlet pressure control range of 1. 5 to 50 MPa (200 to 7 500 psig) or 2 to 76 MPa 300 to 11 000 psig. Maximum inlet pressure is equal to the maximum outlet pressure. © 1998 - 2000 DH Instruments, Inc. Page 14 GB-K Gas Booster Package Operation and Maintenance Manual 3. 1. 5 GAUGES There are three gauges in the unit used to indicate the Shop Drive Air Pressure, Low Pressure Outlet and High Pressure Outlet settings. The Shop Drive Air Pressure Gauge (9) is constructed of brass and is 1. 5 in. (38 mm) in diameter with a range of 0 to 1. 38 MPa (200 psig). It is used to indicate the output pressure of the Shop Drive Air Regulator (10) supplying gas to the air drive section of the gas booster pump. The Low Pressure Outlet Gauge (5) is constructed of stainless steel and is 2 in. (51 mm) in diameter with a range of 0 to 2 MPa (300 psig). It is used to indicate the output of the Low Pressure Outlet Regulator (12). The High Pressure Outlet Gauge (4) is constructed of stainless steel and is 4. in (102 mm) in diameter with a range of 0 to 70 MPa (10 000 psig) or 0 to 103 MPa (15 000 psig). It is used to indicate the output of the High Pressure Outlet Regulator (7). 3. 2 SETTING LOW PRESSURE OUTPUT All previous sections (especially Section 2. 3) should be read, understood and instructions completed before continuing. It is not necessary to open the Shop Drive Air Shut-off Valve (11) when using the low pressure circuit. [. . . ] It is recommended to perform them in the order shown: Close the High Pressure Outlet Regulator (7) and Shop Drive Air Shut-off Valve (11), then increase shop drive air pressure to about 0. 5 MPa (75 psi). Open the Shop Drive Air Shutoff Valve (11) quickly. If the booster begins to operate normally, close the Shop Drive Air Shut-off Valve (11) and reset regulators to previous settings. Repeat the process until the booster begins normal operation. [. . . ]
