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.
The maximum value of 0.7MPa is generally taken. 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.
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.
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.
If the flow is not enough, then we choose another pump with a supercharged ratio and a larger flow rate, and calculate the flow until the system flow requirements are met. Notice that what we mean by traffic is the flow rate under normal pressure, and it will be measured at 1 minutes if the medium (liquid or gas) pumped by a pump is placed at atmospheric pressure to measure its volume.
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.
