气动增压泵分为气液增压泵（气动液体增压泵），气体增压泵（气动气体增压泵）；

Pneumatic booster pumps are divided into gas-liquid booster pumps (pneumatic liquid booster pumps) and gas booster pumps (pneumatic gas booster pumps);

气液增压泵原理是利用大面积活塞的低气压产生小面积活塞的高压液体和高压气体。是靠低压气源来作为驱动力的，实现内部活塞的左右移动个，今天我们就来了解一下订购气动液体增压泵的常识。

The principle of a gas-liquid booster pump is to use the low air pressure of a large area piston to generate high-pressure liquid and gas of a small area piston. It relies on a low-pressure air source as the driving force to achieve left and right movement of the internal piston. Today, we will learn about the common sense of ordering pneumatic liquid booster pumps.

1.工作压力和流量

1. Working pressure and flow rate

所有的泵和动力单元的工作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工作压力，这就要考虑措施。对于大输出压力，请参照产品目录中的“静态下驱动气压力和输出液压近似比率表”。动力单元的选型与泵一致。对于工作流量，请参照产品目录中的“性能曲线图”。

The working pressure of all pumps and power units refers to the pump output pressure and flow rate when the driving air pressure is 0.48Mpa. If the large output pressure of the pump is greater than the required working pressure, safety measures should be considered. For high output pressure, please refer to&quo; in the product catalog; Approximate ratio table for driving air pressure and output hydraulic pressure under static conditions;. The selection of the power unit is consistent with the pump. For work flow, please refer to&quo; in the product catalog; Performance curve chart;.

2.输送液体介质

2. Conveying liquid medium

泵输送的液体介质是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输送的液体介质所决定的。泵可用油、水和大多数液体介质。标准泵的主要液压密封圈是丁橡胶和聚氨酯，单向阀座采用特氟龙密封。其它密封材料包括碳氟化合物和亚乙基丙烯，这些密封材料主要用于输送的特殊介质。请向工厂或当地的分销商咨询密封材料选型。

The liquid medium conveyed by the pump is a key consideration in the selection of the pump. The material and hydraulic sealing ring of the hydraulic part are determined by the liquid medium conveyed. Pumps can be used with oil, water, and most liquid media. The main hydraulic sealing rings of the standard pump are neoprene and polyurethane, and the one-way valve seat is sealed with Teflon. Other sealing materials include fluorocarbon compounds and ethylenepropylene, which are mainly used for conveying special media. Please consult the factory or local distributor for sealing material selection.

3.可接受的体积和重量

3. Acceptable volume and weight

对于某些的应用，泵和动力单元的外形尺寸和重量也要考虑。

For certain applications, the overall dimensions and weight of pumps and power units also need to be carefully considered.
