The pressure is generally 3-8bar (0.3-0.8MPa). Of course, it is not within this pressure range. The pressurization effect of the same Booster pump is the same. The pressurization ratio of the same Booster pump (the area ratio of the driving piston to the supercharging piston) is fixed. Of course, the maximum output pressure at the driving air pressure of 3bar is different from that at the driving air pressure of 8bar.

因此，不要误解为驱动气压要求为3-8bar是指这个压力区间内都能达到同一个压力，气动增压泵的输出压力是与驱动气和预增气的压力息息相关的（驱动气体压*增压倍数=输出压力），所以，设备选型时要根据现场的压缩空气的压力选择合适的增压比，正常情况下，所选设备的输出压力要比实际使用压力大一些，留有一定的余量。因为当压力越接近气体增压泵的输出压力时，增压泵频率越慢，流量越小，达到输出压力相对困难。提高压力比，就可以很好地解决这种问题。

Therefore, it should not be misunderstood that the driving pressure requirement is 3-8bar, which means that the same pressure can be reached within this pressure range. The output pressure of the pneumatic Booster pump is closely related to the pressure of the driving gas and the pre increased gas (the lowest pressure of the driving gas * the boost multiple=the output pressure). Therefore, when selecting the equipment, the appropriate boost ratio should be selected according to the pressure of the on-site compressed air. Under normal circumstances, The output pressure of the selected equipment is slightly higher than the actual usage pressure, leaving a certain margin. Because when the pressure is closer to the maximum output pressure of the gas Booster pump, the frequency of the Booster pump is slower and the flow is smaller. It is relatively difficult to reach the maximum output pressure. Increasing the pressure ratio can effectively solve this problem.

耗气量的要求，一般要求流量≥0.6m?/min左右，耗气量不是一个固定值，当气体增压泵的负载越小时，增压泵的频率越快，负载越大时，气体增压泵的频率越慢，当达到输出压力时，气体增压泵停止工作，不在耗气。空气压缩机的选择上，7.5kW的空压机配套200L以上的气罐，是让气体增压设备正常工作的要求。

The requirement for gas consumption generally requires a flow rate of ≥ 0.6m/ About min, the gas consumption is not a fixed value. When the load of the gas Booster pump is smaller, the frequency of the Booster pump is faster. When the load is larger, the frequency of the gas Booster pump is slower. When the maximum output pressure is reached, the gas Booster pump stops working and no longer consumes gas. In terms of the selection of air compressors, a 7.5kW air compressor paired with a 200L or more air tank is the minimum requirement for the normal operation of gas boosting equipment.
