3 Steps for Correct Selection of Gas Booster Pump

Selection of gas booster pump (short version):1. What type of pressurization medium is it?2. What is the inlet pressure range of pressurized medium?

3. What is the existing air supply pressure?4. Are there requirements for the flow after high pressure?5. Purpose of pressure after pressurization?

1 Determine the type of booster pump according to the booster medium.For example, if the pressurization medium is air / nitrogen, we choose air booster pump / nitrogen booster. The pressurization medium is gas, so we choose gas supercharger; The pressurization medium is liquid, so we choose pneumatic liquid booster pump.Second, the model of the pump is preliminarily determined according to the required pressure of the system.

Generally, the driving air pressure of the pneumatic booster pump of Jiurong manufacturer is 8bar. Therefore, the pressurization ratio is ratio = PO / PA. Where Po is the output pressure of the system; PA is the driving pressure of the pneumatic pump, generally taking the maximum value of 0.7MPa. According to the calculated boost ratio, select the model in the corresponding type of pump table.Note that we usually choose a pump with a boost ratio slightly higher than the calculated value to ensure that our pump can output the pressure required by the system under normal circumstances.Third, check whether the flow of the pump meets the system requirements.

When we preliminarily select the pump model according to the outlet pressure of the pump, we need to check whether the flow of the modified pump meets the requirements. The flow of the pump is calculated as follows: displacement per stroke Action frequency per minute (generally calculated as 40).For example, for pneumatic liquid booster pump 10-4000w003, we found in the pump table that its displacement per stroke is 42.50ml, so its flow Q = Q n=42.50ml 40=1700ml/min=1.7L/min Compare this flow with the flow required by the system to see whether it meets the requirements.If the flow is not enough, we will select a pump with similar boost ratio and large flow, and calculate the flow until the system flow requirements are met.

Note that the flow we mentioned refers to the flow under atmospheric pressure, that is, the volume of the medium (liquid or gas) pressurized by the pump within 1 minute is measured under atmospheric pressure. Therefore, for gas, we need to consider the pre increase pressure.For example, we use an air booster pump to pressurize 7bar air to 1.2MPa, then its flow Q = 7 q n=7 47.6ml 40=13328ml/min=13.328L/minPrecautions for use of gas booster pump:

1. The output pressure shall have margin compared with the pressure required by yourself.2. It is better to install a filter at the high-pressure inlet to reduce the impact of impurities on the product.3. The inlet pressure of the product has strict requirements. Too low inlet pressure directly affects the flow and output pressure of the gas booster pump.

4. Driving air pressure range 8bar, do not overload.5. Clean the pressurization medium, the gas booster pump and the on-site use environment.6. Before use, it is recommended to add an oil-water separator at the driving air source port to often release the water in the water cup.

7. Each time the high-pressure gas booster pump is used up, the high-pressure gas needs to be discharged.8. Regularly check the gas booster pump to maintain the integrity of parts.
