The gas-liquid booster pump is a kind of pump product which takes compressed air as power, based on the principle of area difference, makes the hydraulic oil or other liquid output continuously according to the fixed pressurization ratio and serves as the high-pressure power source. It is a kind of variable displacement piston pump which integrates the power source.
In the initial stage of compressed air connection, the circulation speed is fast and the output liquid flow is large. With the gradual increase of the output pressure, the resistance of the piston is also increasing, and the circulation speed of the pump is becoming slower and slower. When the reaction force of the output pressure on the piston is balanced with the gas driving force, the pump will stop automatically. At this time, the pump is in the pressure holding state without consuming any energy, so it provides an economic power source.
When the output pressure drops or the air supply pressure increases due to leakage or other reasons, the pump will start immediately to supply pressure to the system, which benefits from the low friction resistance of the pump itself and ensures the stability of the output pressure. The pulsation of double acting pump is smaller than that of single acting pump, the output pulsation is smaller, and the output flow is 50% higher than that of single acting pump of the same series.
After the pressure is set up, the pump stops automatically, no noise, no energy consumption, more environmental protection. There is no temperature rise phenomenon of working medium, so it is suitable for use in summer and stuffy places without ventilation. No need of power supply, suitable for no power supply or explosion-proof occasions. Small size, flexible configuration, can bring its own oil tank, can also be remote oil supply, save installation space. The output pressure can reach hundreds of MPA, but the price difference between products with different output pressure is small. The pressure has no impact, is safer, and has no damage to the equipment and parts.
便于维护，泵体结构设计模块化，所有易损件均为标准件，方便安装及拆卸。 气压驱动不需额外的在线润滑管路，既节约了运行成本又避免了油雾对环境 的污染以及人体的伤害。
Easy to maintain, modular design of pump body structure, all vulnerable parts are standard parts, easy to install and disassemble. The pneumatic drive does not need additional on-line lubrication pipeline, which not only saves the operation cost, but also avoids the pollution of oil mist to the environment and human body.
Frequent start and stop have no adverse effect on the pump. The leakage overflow hole is reserved to protect the pump body and detect the pump fault in time. It is easy to maintain and replace, and has longer service life. Within the pressure range of the pump, by adjusting the input air pressure, the output liquid pressure can be adjusted accordingly. According to the requirements of field conditions, from simple manual operation to full-automatic control. The supercharging medium is various, water, oil, coolant, lubricating oil and corrosive fluid can be used
