QST series pneumatic pressure test Taiwan Source: Cape Air Mechanical Author: Cape Air Time: 2015-1-10 16:53:07 Views: 403 I. Features This series of pneumatic pressure test station with compressed air as power source, by air motor driven pump, low pressure input, high hydraulic output devices. By adjusting the air pressure or flow rate, pressure and flow rate changes of the hydraulic pump, the pump therefore has a wide range of applications. Second, use for pipes, BOP, valves, boilers, pressure vessels and all the liquid petroleum engineering pressure test. Pump can be used for pressure source BOP control system. Third, the technical parameters: 1. Low pressure system liquid ratio: one sixty; 2. High-pressure system liquid ratio: 1: 270; 3. Pressure test range: 0-140MPa; 4. Pressure test medium: water (ambient temperature is below 0 ℃ need to add antifreeze), hydraulic oil; 5. Air and water interface thread size 1: internal thread NPT 1; 6. High voltage interface thread size 1: external thread NPT 1/2. Note: 1 "thread size" test-oriented interface thread size platen provides the user interface should be prepared with the corresponding threaded connection of the pressure test station, if there are special requirements in order ordering agreement shall prevail. Fourth, the meaning of words and Model Series Model: Example: QST-140 pneumatic pressure test station: Rated pressure 140MPa, recording: radio records.
