根据系统所需压力初步确定泵的型号。一般地，SC的气动增压泵的驱动气压≤7bar。所以，增压比Ratio=Po/Pa。其中，Po是系统的输出压力；Pa是气动泵的驱动压力，一般取较大值0.7MPa。
The model of the pump is preliminarily determined according to the pressure required by the system. In general, SC pneumatic driven pressure booster pump is less than or equal to 7bar. So, the turbocharging is more than Ratio=Po/Pa. Among them, Po is the output pressure of the system; Pa is the driving pressure of the pneumatic pump, which generally takes the maximum value of 0.7MPa.
根据计算出来的增压比，在相应类型的泵表中选择型号。注意，通常我们会选择增压比略高于计算值的泵，以确保我们的泵在通常情况下都能输出系统所需压力。
According to the calculated turbocharging ratio, select the type in the corresponding type of pump table. Note that we usually choose slightly higher than the calculated value of the booster pump, the pump to ensure that we can output the required pressure system under normal conditions.
根据增压介质确定增压泵类型。比如，增压介质是空气/氮气，我们就在空气增压泵/氮气增压器中选.增压介质是气体，我们就在气体增压器中选；增压介质是液体，我们就在气动液体增压泵中选。
The type of the booster pump is determined according to the supercharging medium. For example, the pressurizing medium is air / nitrogen. We choose it in the air booster pump / nitrogen booster. The pressurizing medium is gas. We choose it in the gas supercharger. The pressurizing medium is liquid. We choose it in the pneumatic liquid booster pump.
核算泵的流量是否满足系统要求。当我们根据泵的出口压力初步选择了泵的型号后，我们需要核算改泵的流量是否满足要求。
Check the flow of the pump to meet the requirements of the system. When we choose the pump model according to the pressure of the pump, we need to check the flow rate of the pump to meet the requirements.
泵的流量计算方法是这样的：每冲程的排量×每分钟的动作频率（一般以40计）。比如，气动液体增压泵10-4000W003，我们在泵表中查到它每冲程的排量是42.50ml，那么它的流量Q=q×n=42.50ml×40=1700ml/min=1.7L/min。将这个流量与系统需要的流量比较，看是否满足要求。
Pump flow calculation method is such: per stroke volume * per minute action frequency (usually 40). For example, the pneumatic liquid booster pump 10-4000W003, we found in the pump table that the displacement of every stroke is 42.50ml, then its flow rate is Q=q * n=42.50ml * 40=1700ml/min=1.7L/min. Compare the flow of this flow with the flow required by the system to see if it meets the requirements.
我们所说的流量都是指常压下的流量，即将1分钟内经过泵增压的介质（液体或气体）放在常压下去测量它的体积。所以，对于气体，我们需要考虑预增气压的大小。
The traffic we refer to refers to the flow rate under atmospheric pressure, and the volume of the medium (liquid or gas) pumped by the pump will be measured at atmospheric pressure in 1 minutes. So, for gas, we need to consider the size of the pre pressure.
根据增压介质选择泵的材质。经过上面3个步骤后，我们可以选出泵的基本型号了。然而，正确的型号还得考虑增压介质对增压泵材质的要求。
Select the material of the pump according to the supercharging medium. After 3 steps above, we can choose the basic model of the pump. However, the correct model must also take into account the requirements of the pressurized medium for the material of the booster pump.
