气液增压泵可在防爆环境运用达到预设压力主动停止，无需电控长时间保压无能源消耗作业过程无热量产操作简单易于安装低成本保护，易于保养。下面来讲讲气液增压泵的术语。
The pneumatic-hydraulic booster pump can be used in the explosion-proof environment to reach the preset pressure and stop automatically, without the need for electric control to maintain the pressure for a long time and without energy consumption. The operation process is heat free and mass production is simple, easy to install, low cost protection, and easy to maintain. Let's talk about the terminology of gas-liquid booster pump.
压力比：驱动活塞与加压活塞的面积比。
Pressure ratio: area ratio of driving piston and pressurized piston.
耗气量：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运送才能能否满意增压泵的需要。
Air consumption: the small air consumption (NL/min) required to drive the piston movement to determine whether the delivery of air compressor or pipeline can meet the needs of booster pump.
驱动压力：驱动增压泵动作的压力规模，理论规模在1。5bar~10bar之间，经济运用规模在6bar~8bar之间。
Drive pressure: the pressure scale of driving booster pump action, the theoretical scale is 1. 5 bar~10 bar, and the economic application scale is 6 bar~8 bar.
排量：增压泵在一个行程内，输出介质的容积（L/次）。
Displacement: the volume of output medium of booster pump in one stroke (L/time).
流量：增压泵在一分钟内，累计输出介质的容积（L/min）。等于排量×每分钟往复次数。流量随输出压力的增大而减小，样本中给出的流量为出口压力为零时的丈量值。
Flow: the cumulative output volume of the booster pump in one minute (L/min). Equal to displacement × Reciprocating times per minute. The flow rate decreases with the increase of the output pressure. The flow rate given in the sample is the measured value when the outlet pressure is zero.
标态流量：仅对气态而言，即在1atm,20°C下丈量的流量。
Standard state flow: only for gas state, that is, the flow measured at 1 atm and 20 ° C.
保压：在一定的驱动压力下，泵停止作业后，回路内的压力在规定时间内没有改变。保压时间少10min。
Pressure maintaining: under a certain driving pressure, after the pump stops working, the pressure in the circuit does not change within the specified time. The pressure holding time is less than 10min.
补压：不管何种原因造成保压回路压力下降，泵将主动发动，补充走漏压力，坚持回路压力安稳。
Make-up pressure: no matter what causes the pressure of the pressure retaining circuit to drop, the pump will start actively to supplement the leakage pressure and maintain the circuit pressure stable.
Now many places on the market sell gas-liquid booster pumps, so it is very helpful to know some of their prices about their own selection, and when selecting the pneumatic pump, you can't just choose its price, you must pay attention to its quality.
