空气增压泵，简单点来说就是用来提升气源压力的一种设备，当然还可以用于气压测试、气密性检测等。产品根据倍数可分为2/5等倍数，倍数越大，高压后流量越小。
Air booster pump, simply speaking, is a kind of equipment used to improve the air source pressure. Of course, it can also be used for air pressure test, air tightness test, etc. According to the multiple, the product can be divided into 2 / 5 and other multiple. The larger the multiple, the smaller the flow after high pressure.
空气增压泵为一种以压缩空气为动力源的一种活塞式增压泵。当进气时增压气控阀的阀芯往复切换工作，控制增压阀活塞以极快的速度作往复动作。随着输出压力增大，活塞的往复速度减慢直到停止，此时，增压泵输出压力达到恒定，各部件停止工作耗能达到。不管是什么原因导致保压回路压力下降，增压泵都会自动启动补充压力以达到回路压力恒定的效果。
Air booster pump is a kind of piston booster pump with compressed air as power source. When the intake air, the valve core of the supercharging gas control valve works reciprocally, which controls the piston of the supercharging valve to reciprocate at a very fast speed. With the increase of the output pressure, the reciprocating speed of the piston slows down until it stops. At this time, the output pressure of the booster pump reaches constant, and the energy consumption of the components stops working reaches the minimum. No matter what causes the pressure drop of the pressure maintaining circuit, the booster pump will automatically start to supplement the pressure to achieve the effect of constant circuit pressure.
1、性价比高：相对于采购一台大的空气压缩机（成本高噪音大），采用空气增压泵来提高气源压力的方式更具性价比。
1. High cost performance: compared with the purchase of a large air compressor (high cost, high noise), using air booster pump to improve the air source pressure is more cost-effective.
2、操作安全：采用气体驱动,无电弧及火花,可在危险场所使用。
2. Operation safety: gas driven, no arc and spark, can be used in dangerous places.
3、自动保压：无论何种原因造成的保压回路压力下降,增压泵都将自动启动,补充泄露压力,保持回路压力稳定。
3. Automatic pressure maintaining: no matter what causes the pressure drop of the pressure maintaining circuit, the booster pump will start automatically to supplement the leakage pressure and keep the circuit pressure stable.
4、输出范围广：仅需要较小气压就能平稳工作,此时获得更小流量,调节进气量后可获得不同流量。
4. Wide output range: only need a small air pressure can work smoothly, at this time to get the minimum flow, after adjusting the air flow can get different flow.
