1.驅動(dòng)氣體的壓力和流量

1. Pressure and flow rate of driving gas

所有的泵和動(dòng)力單元在連續工作時(shí)使用的驅動(dòng)氣壓不超過(guò)0.69Mpa，在間歇工作時(shí)可達到1.03Mpa。在性能狀態(tài)時(shí)氣動(dòng)泵的耗氣量，請參照所需驅動(dòng)氣體流量表。

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.工作壓力和流量

2. Work pressure and flow rate

所有的泵和動(dòng)力單元的工作壓力參照驅動(dòng)氣壓為0.48Mpa時(shí)泵輸出壓力和流量。如果泵的輸出壓力大于所需的工作壓力，這就要考慮措施。對于輸出壓力，請參照產(chǎn)品目錄中的“靜態(tài)下驅動(dòng)氣壓力和輸出液壓近似比率表”。動(dòng)力單元的選型與泵一致。對于工作流量，請參照產(chǎn)品目錄中的“性能曲線(xiàn)圖”。

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.輸送液體介質(zhì)

3. Transporting liquid media

泵輸送的液體介質(zhì)是泵的選型中著(zhù)重考慮的部分。液壓部分的材質(zhì)和液壓密封圈是由輸送的液體介質(zhì)所決定的。泵可用油、水和大多數液體介質(zhì)。標準泵的主要液壓密封圈是丁橡膠和聚氨酯，單向閥座采用特氟龍密封。其它密封材料包括碳氟化合物和亞乙基丙烯，這些密封材料主要用于輸送的特殊介質(zhì)。請向工廠(chǎng)或當地的分銷(xiāo)商咨詢(xún)密封材料選型。

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.可接受的體積和重量

4. Acceptable volume and weight

對于某些的應用，泵和動(dòng)力單元的外形尺寸和重量也要考慮。

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