QY Series Pneumatic Pressure Test Manual Preface The pneumatic pressure test pump is a new pressure test device developed by our company based on the working principle of the pneumatic pressure test device imported from abroad and the actual situation in our country. First, the characteristics It is the use of compressed air as the power source to the pneumatic pump pressure source, the pressure of the mountain and the pressure of the gas supply is proportional to the pressure. By adjusting the pressure of the air supply, the corresponding hydraulic pressure can be obtained. When the gas pressure and hydraulic pressure balance, the pneumatic pump will stop filling pressure, the output hydraulic pressure will also be stable at the preset pressure, by controlling the size of the intake air to control the boost speed. It has explosion-proof, adjustable pressure transmission, step-up speed controllable, small size, light weight, simple operation, reliable performance, wide range of applications and other characteristics. It is especially suitable for high-pressure and extra-high pressure test of anti-blowout equipment, valves, pipes, connectors, pressure vessels and other pressurized equipment in oilfield drilling engineering. Also suitable for scientific research, testing departments for testing tools. Second, the use BOP used for petrochemical engineering, valves, pipes, boilers and other pressure vessels for liquid pressure test. (Pump can be used as pressure source in BOP control system). Third, the model significance and model series QY 140 AJ A- double row of pumps, J-automatic record low instrument, omitted - without working pressure (unit: MPA) pressure test pump serial number Q-pneumatic Y-hydraulic test General Product Parameter Table Model Pneumatic pump is equipped with gas source Pressure (MPa) Rated working pressure (MPa) Automatically record the weight of the printer (Kg) QYl40 1: 5l I Taiwan l: 236 1 Taiwan O.7 32 140 No 305 QYl40J 1: 5l Taiwan l: 236 1 Taiwan 0 7 32 140 1 Taiwan 310 QYl40AJ 1: 51 2 l; 236 2 Taiwan 0 7 32 140 1 Taiwan 400 Fourth, the product works
