气液增压泵是以气体为动力源的一种往复式柱塞泵，利用大面积活塞端的低压气体驱动面转换为小面积活塞端的高压液体，增压比决定泵的大输出压力。
The gas-liquid booster pump is a reciprocating piston pump with gas as the power source. It uses the low-pressure gas driving surface of the large area piston end to convert to the high-pressure liquid of the small area piston end, and the boost ratio determines the large output pressure of the pump.
工作时，当驱动活塞向后运行时，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；当活塞向前运行时，在液体一侧会形成一定压力，压力会将入口处单向阀关闭，出口处单向阀打开，高压液体就从出口处流出。
When working, when the driving piston runs backward, the liquid is sucked into the pump. At this time, the one-way valve at the inlet is opened and the one-way valve at the outlet is closed; When the piston moves forward, a certain pressure will be formed on the liquid side. The pressure will close the check valve at the inlet, open the check valve at the outlet, and high pressure liquid will flow out from the outlet.
气液增压泵能够实现自动循环，当出口压力升高时，泵会减速运行，并对活塞产生一定的阻力，当力平衡时，泵会自动停止运行，此时高压活塞端压力与液压力达到平衡，活塞保持静止，此时能量消耗低，无油温之困扰，各部件停止工作。当出口压力降低或气体驱动压力增加时，液泵会自动启动运行。
The gas-liquid booster pump can realize automatic circulation. When the outlet pressure rises, the pump will slow down and produce a certain resistance to the piston. When the force is balanced, the pump will automatically stop running. At this time, the pressure at the high-pressure piston end is balanced with the hydraulic pressure, and the piston remains stationary. At this time, the energy consumption is low, and there is no oil temperature problem, and all components stop working. When the outlet pressure decreases or the gas driving pressure increases, the liquid pump will automatically start to run.
注意，选购气动液压增压泵要使您订货的增压泵处于好得作业状况，须了解以下的参数：
Note: In order to keep the booster pump you ordered in good working condition, you must know the following parameters:
驱动气体的压力和流量增压泵和动力单元在接连作业时使用的驱动气压不超过0.69Mpa,在间歇作业时可到达1.03Mpa.在佳功能状况时气动泵的耗气量，请参照所需驱动气体流量表。
The pressure and flow of driving gas The driving air pressure used by the booster pump and power unit during continuous operation shall not exceed 0.69Mpa, and can reach 1.03Mpa during intermittent operation. The air consumption of the pneumatic pump under good functional conditions shall refer to the required driving gas flow table.
增压泵和动力单元的作业压力参照驱动气压为0.48Mpa时泵输出压力和流量。如果泵的大输出压力大于所需的作业压力，这就要考虑措施。运送液体介质泵运送的液体介质是增压泵的选型中着重考虑的部分。液压部分的材质和液压密封圈是由运送的液体介质所决议的。泵可用油、水和大多数液体介质。
The operating pressure of booster pump and power unit refers to the pump output pressure and flow when the driving air pressure is 0.48Mpa. If the large output pressure of the pump is greater than the required operating pressure, safety measures should be considered. The liquid medium transported by the liquid medium pump is a key consideration in the selection of booster pump. The material of the hydraulic part and the hydraulic seal ring are determined by the liquid medium delivered. The pump can use oil, water and most liquid media.
其它密封材料包括碳氟化合物和亚乙基丙烯，这些密封材料首要用于运送的特殊介质。请向工厂或当地的分销商咨询密封材料选型。可接受的体积和分量关于某些的应用，增压泵和动力单元的外形尺寸和分量也要要点考虑。更多相关使用事项就来我们网站

Other sealing materials include fluorocarbon and ethylidene propylene, which are mainly used for special medium delivery. Please consult the factory or local distributor for the selection of sealing materials. Acceptable volume and components For some applications, the overall dimensions and components of booster pump and power unit should also be considered.
