气体增压泵和气液增压泵都属于气动增压泵，其中的区别在于增压介质不同，气体增压泵主要用于气体压力，如压缩空气、氮气、氦气、氧气、氢气等。
Gas booster pump and gas-liquid booster pump belong to pneumatic booster pump. The difference lies in different booster media. Gas booster pump is mainly used for gas pressure, such as compressed air, nitrogen, helium, oxygen, hydrogen, etc.
气液增压泵主要用于气瓶内液体压力的检测设备，如水、石油、乳液等。
The gas liquid booster pump is mainly used for detecting liquid pressure in cylinders, such as water, petroleum, emulsion, etc.
气体增压泵、气液增压泵的驱动元件工作原理相同，但压力不同，气体增压泵的活塞、气液增压泵的柱塞式由于气体是可压缩的，液体的可压缩性可以忽略不计。
The driving elements of the gas booster pump and the gas-liquid booster pump work in the same principle, but the pressure is different. The piston of the gas booster pump and the plunger type of the gas-liquid booster pump can be ignored because the gas is compressible.
