1.驱动气体的压力和流量

1. Pressure and flow rate of driving gas

所有的泵和动力单元在连续工作时使用的驱动气压不超过0.69Mpa，在间歇工作时可达到1.03Mpa。在性能状态时气动泵的耗气量，请参照所需驱动气体流量表。

All pumps and power units use a driving air pressure of no more than 0.69 Mpa during continuous operation, and can reach 1.03 Mpa during intermittent operation. At the optimal performance state, please refer to the required driving gas flow rate table for the air consumption of the pneumatic pump.

2.工作压力和流量

2. Work 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。如果泵的输出压力大于所需的工作压力，这就要考虑措施。对于输出压力，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 maximum output pressure of the pump is greater than the required working pressure, safety measures must be considered. For maximum output pressure, please refer to the approximate ratio table of static driving air pressure and output hydraulic pressure in the product catalog. The selection of power units is consistent with that of pumps. For work flow, please refer to the "Performance Curve" in the product catalog.

3.输送液体介质

3. Transporting liquid media

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 of the hydraulic part and the hydraulic sealing ring are determined by the liquid medium being transported. The pump can be used with oil, water, and most liquid media. The main hydraulic sealing rings of the standard pump are butadiene rubber and polyurethane, and the one-way valve seat is sealed with PTFE. Other sealing materials include fluorocarbons and ethylenepropylene, which are mainly used for conveying special media. Please consult the factory or local distributor for the selection of sealing materials.

4.可接受的体积和重量

4. 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 external dimensions and weight of pumps and power units also need to be carefully considered.
