对于压缩空气压力方面一般要为3-8bar(0.3-0.8MPa)，当然不是这个压力范围内，同一台增压泵的增压效果一样的，同一台气动增压泵的增压比（驱动活塞与增压活塞的面积比）是固定的，当然，驱动气压3bar时与驱动气压8bar时的zui大输出压力是不一致的。
For compressed air pressure, it is generally 3-8 bar (0.3-0.8 MPa), but it is not within this pressure range. The boosting effect of the same booster pump is the same, and the boosting ratio of the same pneumatic booster pump (the area ratio of the driving piston to the boosting piston) is fixed. Of course, the driving pressure of 3 bar is different from the high output pressure of 8 bar.
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zui低压*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zui大输出压力时，增压泵频率越慢，流量越小，达到zui大输出压力相对困难。提高压力比，就可以很好地解决这种问题。

Therefore, do not misunderstand it as the requirement for a driving air pressure of 3-8 bar 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 pre added gas (driving gas: low pressure * boost ratio=output pressure). Therefore, when selecting equipment, it is necessary to choose the appropriate boost ratio based on the on-site compressed air pressure. Under normal circumstances, The output pressure of the selected equipment is slightly higher than the actual usage pressure, leaving a certain margin. Because as the pressure approaches the high output pressure of the gas booster pump, the frequency of the booster pump slows down and the flow rate decreases, making it relatively difficult to reach the high 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，当达到大输出压力时，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z低要求。
The requirement for gas consumption generally requires a flow rate of ≥ 0.6m/ Around 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 output pressure is high, the gas booster pump stops working and no longer consumes gas. In terms of the selection of air compressors, the 7.5kW air compressor is equipped with a 200L or more air tank, which is a low requirement for the normal operation of gas boosting equipment.
