相同点
Similarities
空气增压泵与气体增压泵都能够成为气动增压类产品，都是靠内部活塞往复式运动发生的高压。
Air supercharged pump and gas supercharged pump can become pneumatic supercharged products, which are high pressure produced by reciprocating movement of internal piston.
输出的压力都是靠增压比的与驱动气压的联系进行调节得到的。
The output pressure is regulated by the relation between the boost ratio and the driving pressure.
全体部分都是包含增压缸体，驱动缸体，与换向阀这个三个大部分组成。
All parts are composed of three parts: supercharged cylinder block, driving cylinder block and reversing valve.
空气、气体增压泵的等级能够区分为单级、与双级。
The grades of air and gas booster pumps can be divided into single stage and double stage.
它们的输出流量都与驱动气，被增压气成正比联系。
Their output flow is proportional to the driving gas and the pressurized gas.
不同点
Difference
空气增压泵适用于原空压体系要进步压力的工作环境中，气体则是要把一些气体，如氮气，氧气，氦气，氩气等一些不与空气混合的气体进行增压使用。
The air booster pump is suitable for the working environment where the original air pressure system needs to improve the pressure. The gas is used to boost some gases, such as nitrogen, oxygen, helium, argon and other gases which are not mixed with air.
空气增压泵不能够增压气体（特殊情况下除外），气体增压泵能够增压空气。
Air booster pump can not boost gas (except in special cases), gas booster pump can boost air.
气体增压泵对入口压力有着严厉的要求，空气则需要一个空气管即可（3-8bar）。
Gas booster pumps have strict requirements for inlet pressure, and air needs an air tube (3-8 bar).
