Both gas booster pump and gas-liquid booster pump belong to pneumatic booster pump, but the booster media of the two pumps are different. Gas booster pump is mainly used for gas pressurization, such as compressed air, nitrogen, helium, oxygen, hydrogen, etc; The gas-liquid booster pump is mainly used for liquid pressurization, such as water, hydraulic oil, emulsion, etc. the working principle of the driving part of the gas booster pump and the gas-liquid booster pump is the same, but the pressurizing part is different. The gas booster pump is piston type and the gas-liquid booster pump is plunger type

因为气体是可压缩的,液体的可压缩性可以忽略不计,使用气液增压泵是无法增压气体的,如用来增压气体,由气液增压泵的工作腔内有间隙,气体在压缩腔内压缩膨胀,但不能被压缩出去.气体增压泵可以用来增压气体,可以用来增压液体,那为什么不使用气体增压泵增压液体呢,原因是因为气体增压泵为活塞式的,增压不同很高,增压液体的压力也会很高,气体增压泵和气液增压泵选用的密封结构也不一样,所以,一般情况下这两种泵是不能混用的.

Because the gas is compressible and the compressibility of the liquid is negligible, the gas cannot be pressurized by using the gas-liquid booster pump. For example, there is a gap in the working chamber of the gas-liquid booster pump, and the gas is compressed and expanded in the compression chamber, but it cannot be compressed out. The gas booster pump can be used to pressurize the gas and the liquid, Then why not use the gas booster pump to pressurize the liquid? The reason is that the gas booster pump is piston type, the pressurization is very high, the pressure of the pressurized liquid will be very high, and the sealing structure of the gas booster pump and the gas-liquid booster pump is also different. Therefore, generally, the two pumps cannot be mixed
