空气增压泵是利用压缩空气作为动力，对压缩空气进行增压，增压比有2：1和5：1两种（即可对被增压介质进行两倍或五倍的增压）。空气增压泵是一个的增压单元，串联在被增压管路中。具有增压速度快，使用寿命长，压力稳定，流量大，操作简单，维护方便，使用等特点。下面介绍下空气增压泵的特点。空气增压泵的特点一路充入增压室a和b；另一路向驱动室b充气，驱动室a排气。大活塞左移，增压室b增压，小活塞走到头，换向阀切换，驱动室a进气，驱动室b排气，大活塞反向运动，增压室a增压。
The air booster pump uses the compressed air as the power to pressurize the compressed air. There are two pressurization ratios: 2:1 and 5:1 (that is, twice or five times the pressurization of the pressurized medium). The air booster pump is a booster unit, which is connected in series in the pressurized pipeline. It has the characteristics of fast pressurization speed, long service life, stable pressure, large flow, simple operation, convenient maintenance and use. The following describes the characteristics of the air booster pump. The characteristics of the air booster pump are that it is filled into the booster chambers a and B all the way; The other way inflates the drive chamber B and exhausts the drive chamber a. The large piston moves to the left, the booster chamber B is pressurized, the small piston comes to the end, the reversing valve is switched, the drive chamber a is intake, the drive chamber B is exhaust, the large piston moves in the opposite direction, and the booster chamber a is pressurized.
空气增压泵是用压缩空气驱动大面积端活塞，小面积端得到高压液体输出。适用于压缩空气、氧气、氢气、氩气、天然气、氦气、氮气、甲烷等大部分惰性气体增压。
The air booster pump uses compressed air to drive the large area end piston, and the small area end gets high-pressure liquid output. It is suitable for pressurization of most inert gases such as compressed air, oxygen, hydrogen, argon, natural gas, helium, nitrogen and methane.
空气增压泵可以增压多少，要看驱动气压大小PA（1~8bar）和增压倍数（2倍、5倍、10倍、25倍、40倍、60倍、100倍），空气增压泵出口压力计算公式=增压倍数*驱动气压。驱动气压是8，两倍空气增压泵就是超值压力16公斤，5倍空气增压泵就是超值压力40公斤。以此类推。
How much the air booster pump can boost depends on the driving air pressure PA (1 ~ 8bar) and the boost multiple (2 times, 5 times, 10 times, 25 times, 40 times, 60 times and 100 times). The calculation formula of the outlet pressure of the air booster pump = boost multiple * driving air pressure. The driving air pressure is 8, twice the value pressure of the air booster pump is 16 kg, and five times the value pressure of the air booster pump is 40 kg. and so on.
其实空气增压泵要不要加气罐，要看具体情况，并不是说一定要加的。如果你需要空气增压泵打压压力更稳定的话，那么空气增压泵是要搭配储气罐的，因为储气罐是专门用来储存气体的设备，同时起稳定系统压力的作用。
In fact, whether the air booster pump needs an air tank depends on the specific situation, not necessarily. If you need a more stable pressurization pressure of the air booster pump, the air booster pump should be matched with the air tank, because the air tank is a special equipment for storing gas and stabilizing the system pressure at the same time.
因为空气增压泵自身的原因导致增压后的气体不是一直输出而是像活塞式空压机一样，一股一股的输出这样会导致部分设备因为脉冲使用不正常，这个时候就需要一个储气罐来缓解脉冲的影响和瞬间释放的大流量需求。
Because of the reasons of the air booster pump itself, the pressurized gas is not output all the time, but output one by one like the piston air compressor, which will lead to the abnormal use of some equipment because of the pulse. At this time, an air storage tank is needed to alleviate the impact of the pulse and the large flow demand of instantaneous release.
