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.

随着输出压力的逐渐提高，活塞承受的阻力也越来越大，泵的循环速度也越来越慢。当输出压力对活塞的反作用力与气体驱动力达到平衡时，泵将自动停止。这时泵处于保压状态而不消耗任何能量，因此它提供一种经济的动力源。

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.

当因泄露或其它原因引起输出压力下降或者提供的气源压力升高时泵会立即启动，给系统补压，这得益于泵自身较低的摩擦阻力，并保证输出压力的稳定性。双作用泵比单作用泵的脉动更小，输出脉动更小，输出流量比同系列的单作用泵提高50%。

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.

工作原理:

working principle:

压力建立后，泵自动停止，没有噪音不，不消耗能源，更为环保。没有工作介质温升现象，适合在夏季及闷热无通风场合使用。不需要电源，适合无电源或防爆场合。体积小配置灵活，可自带油箱，也可远端供油，节省安装空间。输出压力可达上百兆帕，但不同输出压力产品之间的价位差异不大。

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 not big.

压力没有冲击，更安 全，对设备和零件没有损伤。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。频繁的启动、停止对泵无任不好影晌。预留密封泄漏溢流孔，在保护泵体同时，亦可及时发现泵的故障。采用换向阀外置，便于维修更换，并且寿命更长。

The pressure has no impact, is safer, and has no damage to the equipment and parts. 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 bad 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.

在泵的压力范围内，通过调节输入气压，输出液体压力即可得到相应调整。根据现场工况要求，从简单的手动操作到全自动控制。增压介质多样，水、油、冷却液、润滑油以及有腐蚀性流体均可以使用。

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 pressurization medium is various, water, oil, coolant, lubricating oil and corrosive fluid can be used.
