驱动空气压力一般要为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致的，同一台增压泵的增压比（驱动活，塞与增压活，塞的面积比）是固定的，驱动气压3bar时与驱动气压8bar时的输出压力是不一致。
The driving air 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 driving air, plug and pressurization air, plug) is fixed. The maximum output pressure at the driving air pressure of 3bar is inconsistent with that at the driving air pressure of 8bar.
因此不要误解为驱动气压要求为3-8bar，就是指这个压力区间内都能达到同一个压力，因此选型时要根据现场的压缩空气的压力选择合适的增压比，一般压力要留有一定的余量。当压力越接近泵的输出压力时，泵的频率越慢，流量越小。
Therefore, do not misunderstand it as the driving air pressure requirement is 3-8 bar, which means that the same pressure can be reached within this pressure range. Therefore, when selecting the type, it is necessary to choose the appropriate boost ratio based on the on-site compressed air pressure, and generally leave a certain margin for pressure. As the pressure approaches the maximum output pressure of the pump, the frequency of the pump slows down and the flow rate decreases.
原理是大活，塞推动小活，塞往复运动实现增压，随着压力的出口端压力的上升，大活，塞和小活，塞的两端的力趋于平衡，故增压泵运动频率下降、流量变小，当出口端的压力是增压泵的增压比时，两端力值平衡，增压泵这时停止工作，流量为0，一旦一端气压下降，增压泵会自动工作，补齐压力，具有自动保压、补压功能。
The principle is that when the pressure at the outlet end of the pressure rises, the force at both ends of the plug tends to balance, so the movement frequency of the Booster pump decreases and the flow becomes smaller. When the pressure at the outlet end is the boost ratio of the Booster pump, the force values at both ends are balanced, and the Booster pump stops working at this time, the flow is 0. Once the pressure at one end drops, the Booster pump will automatically work to supplement the pressure, Equipped with automatic pressure maintaining and compensating functions.
耗气量的要求，一般要求流量1m3/min左右，耗气量不是一个固定值，当泵的负载越小时，泵的频率越快，负载越大时，泵的频率越慢，当达到泵的输出压力时，泵停止工作，不在耗气。不建议选用220V电源的空气压缩机，220V的空压机排气量一般都较小，增压泵不能发挥出正常效能。
The requirements for gas consumption generally require a flow rate of about 1m3/min, and the gas consumption is not a fixed value. The smaller the pump load, the faster the pump frequency. The larger the load, the slower the pump frequency. When the maximum output pressure of the pump is reached, the pump stops working and no longer consumes gas. It is not recommended to select an air compressor with 220V power supply. Generally, the Engine displacement of 220V air compressor is small, and the Booster pump cannot play a normal role.
