1. Pressure ratio: area ratio of driving piston to pressurizing piston.

2. 耗气量：驱动活塞运动所需要的更小耗气量（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。

2. Air consumption: the minimum air consumption required to drive the piston movement (NL / min) to determine whether the conveying capacity of the air compressor or pipeline can meet the needs of the booster pump.

3. 驱动压力：驱动增压泵动作的压力范围，理论范围在1.5bar~10bar之间，更经济使用范围在6bar~8bar之间。

3. Driving pressure: the pressure range for driving the booster pump. The theoretical range is 1.5bar ~ 10bar, and the most economical range is 6bar ~ 8bar.

4. 排量：增压泵在一个行程内，输出介质的容积（L/次）。

4. Displacement: the volume of the output medium of the booster pump in one stroke (L / time).

5. 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测量值。

5. Flow: the booster pump accumulates the volume of output medium (L / min) within one minute. Equal to displacement & times; Number of reciprocations per minute. The flow decreases with the increase of output pressure. The flow given in the sample is the measured value when the outlet pressure is zero.

6. 标态流量：仅对气态而言，即在1atm，20°C下测量的流量。

For the standard flow rate, i.e. only in the gas state of 1A & 6; Flow measured at C.

7. 保压：在一定的驱动压力下，泵停止工作后，回路内的压力在规定时间内没有变化。保压时间更少10min。

7. 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 shall be at least 10min.

8 .补压：无论何种原因造成保压回路压力下降，泵将自动启动，补充泄漏压力，保持回路压力稳定。

8 . Pressure supplement: no matter what causes the pressure drop of the pressure maintaining circuit, the pump will start automatically to supplement the leakage pressure and maintain the stability of the circuit pressure.
