Pneumatic-hydraulic booster pump is a kind of pump product, which is driven by compressed air and continuously outputs hydraulic oil according to fixed boost ratio based on the principle of area difference.

气液泵自动循环工作。在紧缩空气接通初期，它做为普通液体保送泵，此时循环速度快，输出液体流量较大。随着输出压力的逐步进步，活塞接受的阻力也越来越大，泵的循环速度也越来越慢。

The gas-liquid pump circulates automatically. In the initial stage of tight air connection, it acts as a common liquid delivery pump, at which time the circulation speed is the fastest and the output liquid flow rate is the largest. With the gradual progress of the output pressure, the resistance of the piston acceptance is also increasing, and the circulation speed of the pump is also slower and slower.

当输出压力的反作用力与气动驱动力到达均衡时，泵将自动停下来。这时泵处于保压状态而不耗费任何能量，因而它提供了一个经济的动力源。

When the reaction force of the output pressure reaches equilibrium with the pneumatic driving force, the pump will stop automatically. At this time, the pump is in a pressure-holding state and does not consume any energy, so it provides an economic power source.

当因泄露或其他缘由惹起输出压力的降落时或提供的气源压力升高时泵会立刻启动，这些都得益于泵本身较低的摩擦阻力，并保证了输出压力的牢靠性。

When the output pressure drops due to leakage or other reasons or when the supply pressure rises, the pump will start immediately, which benefits from the lower friction resistance of the pump itself and ensures the reliability of the output pressure.

与普通液压站相比：

Compared with common hydraulic stations:

⒈由于可较长时间保压，不额外耗费能源，故俭省能源。

_Because it can keep pressure for a long time and does not consume extra energy, it saves energy.

⒉无油温升高，故合适夏季及闷热无通风场所运用。

_There is no increase in oil temperature, so it is suitable for use in summer and in hot and non-ventilated places.

⒊气液增压泵不需求电源，所以合适在无电源场所。

_Gas-liquid booster pump does not need power supply, so it is suitable in places without power supply.

⒋体积小配置灵敏，能够自带油箱，也能够装置在机床上，应用床身的空间，俭省消费面积。

_Small size, sensitive configuration, can bring its own tank, can also be installed on the machine, the application of bed space, saving consumption area.

⒌对环境不形成污染。

_It does not pollute the environment.

与增压缸相比：

Compared with supercharger cylinder:

由于气液增压泵可自动连续供油，故没有增压缸行程限制出油量的问题。

Since the gas-liquid booster pump can automatically and continuously supply oil, there is no problem of restricting the oil output by the stroke of the booster cylinder.
