气液增压泵术语:
Terminology of gas-liquid booster pump:
1.压力比:驱动活塞与压力活塞的面积比。
1. Pressure ratio: area ratio of driving piston to pressure piston.
2.耗气量:驱动活塞所需要的更小耗气量(NL/min)，以确定空压机或管道的输送能力是否能满足增压泵的需要。
2. Air consumption: the minimum air consumption required to drive the piston (NL / min), to determine whether the delivery capacity of air compressor or pipeline can meet the needs of booster pump.
3.驱动压力:增压泵作用的理论压力范围为1.5bar - 10bar，更经济的范围为6bar - 8bar。
3. Driving pressure: the theoretical pressure range of booster pump is 1.5bar - 10bar, and the most economical range is 6bar - 8bar.
4.排量:增压泵一次行程内输出介质的体积(L/次)。
4. Displacement: volume of output medium in one stroke of booster pump (L / time).
5.流量:增压泵输出介质在1分钟内的累计容积(L/min)。等于位移乘以每分钟。流量随着输出压力的增大而减小，试样中给出的流量为出口压力为0时的测量值。
5. Flow: the cumulative volume of the output medium of booster pump within 1 minute (L / min). Equal to displacement times per minute. The flow rate decreases with the increase of the output pressure, and the flow rate given in the sample is the measured value when the outlet pressure is 0.
6.标准流量:仅适用于气相，即1atm时，C下测量流量为20°。
6. Standard flow: only applicable to gas phase, i.e. at 1atm, the flow measured at C is 20 °.
7.保压:在一定的驱动压力下，泵停止工作后，回路压力在规定时间内不发生变化。更小等待时间为10min。
7. Pressure maintaining: under a certain driving pressure, after the pump stops working, the circuit pressure does not change within the specified time. The minimum waiting time is 10min.
8.补压:无论什么原因引起保持回路压降，泵都会自动启动，补充泄漏压力，保持回路压力稳定。
8. Make up pressure: no matter what causes the pressure drop in the holding circuit, the pump will start automatically to make up the leakage pressure and keep the circuit pressure stable.
如何选择气液增压泵?
How to choose gas-liquid booster pump?
1. 注意留出足够的实际压力
1. Pay attention to leave enough actual pressure2. 现场压缩空气压力一般要求为2-8bar
2. The general pressure of compressed air on site is 2-8bar3.压力介质，中等温度
3. Pressure medium, medium temperature
4. 所需流量，如压力检测，表示产品的体积和需要的升压速度，气液增压泵输出压力的计算公式为:
4. The required flow, such as pressure detection, indicates the volume of the product and the required boosting speed. The calculation formula of the output pressure of the gas-liquid booster pump is:
输出压力=压缩空气压力×压力比
Maximum output pressure = compressed air pressure × pressure ratio气液增压泵流量说明:
Flow description of gas-liquid booster pump:
1. 标记流由气液增压泵压力大于6条,出口压力接近于零应力状态,水流(2)的介质压力介质粘度、流动,如介质水和46 #液压油,流率差异较大,气液增压泵的流动一般模糊流量,准确流3。气液增压泵入口连接时，应尽量满足相应的管径，不能越小越通，要接小通径，流量减小。
1. The pressure of the marked flow is more than 6 from the gas-liquid booster pump, and the outlet pressure is close to the zero stress state. The viscosity and flow of the medium pressure medium of the water flow (2), such as medium water and 46 × hydraulic oil, vary greatly in the flow rate. The flow of the gas-liquid booster pump is generally fuzzy and accurate. When the inlet of the gas-liquid booster pump is connected, the corresponding pipe diameter shall be met as much as possible, and the smaller the pipe diameter is, the smaller the pipe diameter is, the smaller the flow rate is.
