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.

在压缩空气接通初期循环速度快，输出液体流量大。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。

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.

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.

气液增压泵优势优于小型液压站：

The advantage of gas-liquid booster pump is better than that of small hydraulic station

1.压力建立后，泵自动停止，没有噪音，不消耗能源，更为环保

1. After the pressure is set up, the pump will stop automatically without noise, energy consumption and environmental protection

2.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

2. There is no temperature rise of working medium, so it is suitable for use in summer and stuffy places without ventilation

3.气液增压泵不需要电源，适合无电源或防爆场合

3. The gas-liquid booster pump does not need power supply, which is suitable for the occasions without power supply or explosion-proof

4.体积小配置灵活，可以自带油箱，也可以安装在机器上，节省安装空间

4. Small size, flexible configuration, can bring its own oil tank, can also be installed on the machine, saving installation space

5.输出压力可高达上百兆帕，但各种输出压力产品之间的成本没有太大差异

5. The output pressure can be as high as 100 MPa, but the cost of various output pressure products is not much different

6.压力没有冲击，更 安 全，对设备和零件没有损伤

6. No pressure impact, safer, no damage to equipment and parts

7.增压介质多样，水、油、冷 却液、润滑油和有腐蚀性流体均可以使用优于增压缸：可自动连续供油，没有增压缸行程限 制出油量的问题

7. The supercharging medium is various, and water, oil, coolant, lubricating oil and corrosive fluid can be used. It is superior to the supercharging cylinder: it can supply oil automatically and continuously, and there is no problem that the stroke of the supercharging cylinder limits the oil output
