1. It can be maintained at any predetermined pressure, no energy consumption, no heat generation, no spark and flame danger;
2. Pressure linear output, easy to manual control; pneumatic booster pump up to 7000bar pressurization capacity, to meet most high pressure needs; easy to be used in automatic control system; continuous start and stop, unlimited, no adverse effects;
3. There is no need to add lubricating oil to the pneumatic piston ring and other pneumatic components when they are working, which can save the operation cost and prevent the oil and gas from polluting the environment;
4. Compressed air is used as power source without power supply; there is no oil lubrication when the pneumatic hydraulic pump is running.
Pneumatic pressure testing pump is a kind of pressure testing device developed according to the working principle of pneumatic pressure testing device. It uses compressed air as the power source and pneumatic pump as the pressure source. The output liquid pressure is proportional to the air source pressure. By adjusting the air source pressure, the corresponding hydraulic pressure can be obtained. When the gas pressure and the hydraulic pressure are balanced, the pneumatic pump stops charging, and the output liquid pressure is stabilized at the preset pressure. By controlling the amount of air intake, the speed of pressure rise is controlled. Therefore, it has the characteristics of explosion-proof, adjustable output pressure, controllable pressure rise speed, small volume, light weight, simple operation, reliable performance and wide application.
It is especially suitable for high pressure and ultra-high pressure test of blowout prevention equipment, valves, pipelines, connectors, pressure vessels and other pressure equipment in oil field drilling and production engineering. At the same time, it is also suitable for scientific research and inspection departments. Pneumatic pressure testing pump is mainly used for liquid pressure test of BOP, valve, pipeline, boiler and other pressure vessels in petrochemical engineering. (the pump can be used as pressure source in BOP control system). Pneumatic pressure testing pump is a new type of pressure testing device developed by our company according to the working principle of pneumatic pressure testing device imported from abroad and combined with the actual situation of our country. It is the use of compressed air power source, with pneumatic pump as the pressure, the output liquid pressure is proportional to the air source pressure.
By adjusting the air source pressure, the corresponding hydraulic pressure can be obtained. When the gas pressure and hydraulic pressure balance, the pneumatic pump will stop charging, and the output liquid pressure will be stabilized at the preset pressure, by controlling the intake volume
