气动液体增压泵的选型要注意哪些?

1.工作压力和流量
1. Working Pressure and Flow
气动增压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。如果泵的最大输出压力大于所需的工作压力,这就要考虑安全措施。对于最大输出压力,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 pneumatic booster pump and power unit refers to the output pressure and flow rate of the pump when the driving pressure is 0.48Mpa. If the maximum output pressure of the pump is greater than the required working pressure, safety measures should be considered. For maximum output pressure, please refer to the "Approximate Ratio Table of Driving Pressure and Output Hydraulic Pressure under Static Conditions" in the catalogue. The selection of power unit is consistent with that of pump. For workflow, please refer to the "Performance Curve" in the product catalog.
2.驱动气体的压力和流量
2. Pressure and flow rate of driving gas
气动增压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。在最佳性能状态时气动泵的耗气量,请参照所需驱动气体流量表。
The driving pressure of pneumatic booster pump and power unit is not more than 0.69 Mpa in continuous operation and 1.03 Mpa in intermittent operation. In the best performance state, the air consumption of the pneumatic pump, please refer to the required driving gas flow meter.
3.输送液体介质
气体增压泵
3. delivery of liquid media
气动增压泵泵输送的液体介质是气动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 pneumatic booster pump is an important part in the selection of pneumatic booster pump. The material quality of the hydraulic part and the hydraulic seal ring are determined by the liquid medium conveyed. Pumps can use oil, water and most liquid media. The main hydraulic sealing rings of standard pumps are polybutadiene rubber and polyurethane, and the one-way seat is sealed with Teflon. Other sealing materials include fluorocarbons and ethylene propylene, which are mainly used for special media for transportation. Please consult the factory or local distributor for seal material selection.
4.气动增压泵可接受的体积和重量对于某些的应用,气动增压泵和动力单元的外形尺寸和重量也要重点考虑
4. For some applications, the acceptable volume and weight of pneumatic booster pump and power unit should also be taken into account.
