Air-hydraulic booster pump product introduction — Yuanli Fluid

Aug 31,2023

Pneumatic-hydraulic booster pumps utilize compressed air as power, based on the principle of area difference (Boyle's Law), to continuously output hydraulic oil or other liquids at a fixed pressure ratio, serving as a high-pressure power source. They are variable plunger pumps that integrate the power source. Double-acting pumps exhibit less pulsation than single-acting pumps, resulting in higher output flow, a 50% increase compared to single-acting pumps in the same series.

Applications Typical applications: Providing static and burst testing for pipe fittings, hoses, valves, pressure vessels, and cylinders; powering automotive braking systems and injector testing; providing power for hydraulic equipment such as clamping, forming, drilling, shearing, and stamping; water jetting for high-pressure cleaning and water cutting equipment; overpressure protection for large presses; and providing cushioning and lifting power for molds.

Features and Advantages:

After pressure is established, the pump automatically stops, resulting in no noise and no energy consumption, making it more environmentally friendly.
There is no increase in working medium temperature, suitable for use in summer or stuffy, unventilated environments.
No power supply is required, suitable for locations without power or explosion-proof environments.
Compact size and flexible configuration; it can have a built-in oil tank or remote oil supply, saving installation space.
Output pressure can reach hundreds of megapascals, but the price difference between products with different output pressures is not significant.
Pressure is shock-free, safer, and causes no damage to equipment or parts.
Easy to maintain; the pump body has a modular design, and all wearing parts are standard parts, making installation and disassembly easy.
Pneumatic drive does not require additional online lubrication lines, saving operating costs and preventing oil mist from polluting the environment and harming humans.
Frequent starts and stops have no adverse effect on the pump.
A reserved sealing leak overflow hole protects the pump body and allows for timely detection of pump malfunctions.
The reversing valve is external for easy maintenance and replacement, and it has a longer lifespan.
Within the pump's pressure range, the output liquid pressure can be adjusted by adjusting the input air pressure.
From simple manual operation to fully automatic control, depending on site conditions.
Multiple boosting media can be used, including water, oil, coolant, lubricating oil, and corrosive fluids.
