气动液压泵将较低的空气压力转换成高压油，即利用大面积活塞端的低气压产生小面积活塞端的高液压。可以代替手动或电动液压泵与锚索张拉机具、退锚机、锚杆拉力计或其他液压工具配套使用

The pneumatic hydraulic pump converts the lower air pressure into high-pressure oil, that is, the low air pressure at the large area piston end is used to generate the high hydraulic pressure at the small area piston end. Instead of manual or electric hydraulic pump, it can be used together with anchor cable tensioning machine, anchor retractor, anchor bolt tension meter or other hydraulic tools;

气动液压泵原理：

　　气动液压泵(气驱液压泵)可以冲水，充油或填充化学介质。气体驱动压力范围为1-10bar。其工作原理类似于往复循环的增压器。其底部活塞由二位四通先导阀来控制。

Principle of pneumatic hydraulic pump:

Pneumatic hydraulic pump (pneumatic drive hydraulic pump) can flush, fill oil or fill chemical medium. The gas drive pressure range is 1-10bar. Its working principle is similar to that of a reciprocating supercharger. The bottom piston is controlled by a two position four-way pilot valve.

气动液压泵为自填充型泵，一般来说，无需使用空气管线润滑器。当驱动活塞向上运行时，将液体吸入泵内，此时入口处的单向阀打开，出口单向阀关闭。当活塞向下运行时，在液体一侧会形成压力，压力会将入口处单向阀关闭，出口处单向阀打开，气动液压泵能够实现自动循环。当出口压力升高时，气动液压泵会减速运行，并对差动活塞产生阻力，当力平衡时，气动液压泵自动停止运行。当出口压力降低或气体驱动压力增加时，气动液压泵会自动启动运行。

Pneumatic hydraulic pumps are self filling pumps and generally do not require the use of air line lubricators. When the driving piston runs upward, the liquid is sucked into the pump. At this time, the check valve at the inlet is opened and the check valve at the outlet is closed. When the piston runs downward, a certain pressure will be formed on the liquid side, which will close the check valve at the inlet and open the check valve at the outlet. Pneumatic hydraulic pump can realize automatic circulation. When the outlet pressure increases, the pneumatic hydraulic pump will slow down and produce a certain resistance to the differential piston. When the force is balanced, the pneumatic hydraulic pump will automatically stop running. When the outlet pressure decreases or the gas drive pressure increases, the pneumatic hydraulic pump will start automatically.
