气体增压泵具有输出性能高而成本低的特性，而且增压泵的零件及密封少，维护简单且成本低着一起复增压。那么您在采购气体增压泵前需要了解的关键词有哪些呢？
The gas booster pump has the characteristics of high output performance and low cost, and the booster pump has fewer parts and seals, simple maintenance and low cost for re pressurization. What keywords do you need to know before purchasing gas booster pump?
压力比：气体增压泵驱动活塞与加压活塞的面积比。常用的压力比：2:1、3:1、4:1……160:1等等。
Pressure ratio: the area ratio between the driving piston and the pressurizing piston of the gas booster pump. Common pressure ratioses: 2:1, 3:1, 4:1... 160:1, etc.
耗气量：气体增压泵驱动活塞运动所需要的小耗气量（NL/min），来确定空压机或管道的输送能力能否满足增压泵的需要，正常情况下，气体增压泵要求的空压机小耗气量≥0.6m?/min，相同驱动气压力下，空压机提供的出气流量越大，气体增压泵工作越快，增压速率越高。
Air consumption: the small air consumption (NL/min) required by the gas booster pump to drive the piston movement to determine whether the delivery capacity of the air compressor or pipeline can meet the needs of the booster pump. Under normal circumstances, the small air consumption of the air compressor required by the gas booster pump is ≥ 0.6m/ Min, under the same driving air pressure, the greater the air outlet flow provided by the air compressor, the faster the gas booster pump works, and the higher the pressurization rate.
?驱动压力：气体增压泵驱动增压泵动作的压力范围，理论范围在2bar~10bar之间，经济使用范围在6bar~8bar之间，驱动气作为气体增压泵的动力源，压力越高，乘以增压比的系数越大，输出的压力也就越大。
? Driving pressure: the operating pressure range of the booster pump driven by the gas booster pump. The theoretical range is between 2bar and 10bar, and the economic use range is between 6bar and 8bar. As the power source of the gas booster pump, the higher the pressure, the greater the coefficient multiplied by the boost ratio, and the greater the output pressure.
排量：气体增压泵在一个行程内，输出介质的容积（nL/次），气体增压泵的排量算法为：加压活塞面积X加压活塞有效行程=这台增压泵的排量。
Displacement: the volume of the output medium (nL/time) of the gas booster pump within a stroke. The displacement algorithm of the gas booster pump is: pressurized piston area X effective stroke of the pressurized piston=the displacement of this booster pump.
流量：气体增压泵在一分钟内，累计输出介质的容积（nL/min）。计算方法为：排量×每分钟增压泵往复次数=增压泵的实际输出流量。由于随着气体增压泵输出端的压力越来越高，对设备输出高压的过程会产生阻尼，所以流量随输出压力的增大而减小，市面上看到的给出的流量很高，均为为出口压力为零时的测量值。
Flow: the cumulative output medium volume of the gas booster pump within one minute (nL/min). Calculation method: displacement × Reciprocating times of booster pump per minute=actual output flow of booster pump. As the pressure at the output end of the gas booster pump becomes higher and higher, the process of outputting high pressure to the equipment will be damped, so the flow will decrease with the increase of the output pressure. The flow given on the market is very high, which is the measured value when the outlet pressure is zero.
标态流量（nL）：仅对气态而言，即在一个标准大气压下，环境20℃下测量的流量。
Standard state flow (nL): only for gas state, that is, the flow measured at 20 ℃ under a standard atmospheric pressure.
保压：设备启动后，在保证稳定的驱动压力下，气体增压泵增压相应压力，设备停止工作，回路内的压力在规定时间内没有变化，保压时间少可以30min。
Pressure maintaining: after the equipment is started, the gas booster pump is pressurized to the corresponding pressure under the stable driving pressure, and the equipment stops working. The pressure in the circuit does not change within the specified time, and the pressure maintaining time can be as short as 30min.
补压：无论何种原因造成保压回路压力下降，气体增压泵将自动启动，补充泄漏压力，保持回路压力稳定。
Pressure make-up: no matter what causes the pressure drop of the pressure maintaining circuit, the gas booster pump will automatically start to supplement the leakage pressure and keep the circuit pressure stable.
