Secondary pressurization with compressed air in the plant is suitable for local high-pressure occasions.
By using the principle of force balance, the compressed air drives the piston with large area and the piston with small area gets high pressure gas output.
The larger the area ratio, the higher the output pressure.
The output flow is adjusted according to the flow rate of driving compressed air.
No oil lubrication, pneumatic piston ring and other pneumatic components do not need to add lubricating oil when they are in working state, which can save operation cost, prevent oil and gas pollution and meet environmental protection requirements.
When the set output pressure is reached, the big and small pistons reach the balance, and the booster pump stops working. At this time, there is no energy consumption and no heat generation. It has good pressure retention characteristics. When there is pressure leakage, the booster pump automatically replenishes the pressure, and frequent starting has no effect.
No lubrication, easy automatic control, no special maintenance.
Because it doesn't need electricity and has no spark, it is suitable for coal mine, petrochemical, chemical and other explosion-proof occasions.
Typical application of compressed air booster pump
Provide air tightness test for valves, fittings, pressure vessels, etc
Local pressurization of production line
High pressure tire inflation
Air pressure test of can
