Pneumatic booster pumps are suitable for high pressure and low flow situations (Hanfu gas booster pump HFT can boost pressure in low pressure situations), suitable for petroleum, scientific research, machinery, testing and other occasions, but not suitable for civilian and high flow output situations.

對于壓力方面一般要為3-8bar(0.3-0.8MPa)，當然不是這個(gè)壓力范圍內，同一臺增壓泵的增壓效果一樣的，同一臺增壓泵的增壓比（驅動(dòng)活塞與增壓活塞的面積比）是固定的，當然，驅動(dòng)氣壓3bar時(shí)與驅動(dòng)氣壓8bar時(shí)的大輸出壓力是不一致的。

In terms of pressure, it is generally 3-8 bar (0.3-0.8 MPa), which is not within this pressure range. The boosting effect of the same booster pump is the same, and the boosting ratio of the same booster pump (the area ratio of the driving piston to the boosting piston) is fixed. Of course, the large output pressure when the driving air pressure is 3 bar is inconsistent with when the driving air pressure is 8 bar.

因此，不要誤解為驅動(dòng)氣壓要求為3-8bar是指這個(gè)壓力區間內都能達到同一個(gè)壓力，氣動(dòng)增壓泵的輸出壓力是與驅動(dòng)氣和預增氣的壓力息息相關(guān)的（驅動(dòng)氣體低壓*增壓倍數=輸出壓力），所以，設備選型時(shí)要根據現場(chǎng)的壓縮空氣的壓力選擇合適的增壓比，正常情況下，所選設備的輸出壓力要比實(shí)際使用壓力大一些，留有一定的余量。因為當壓力越接近氣體增壓泵的大輸出壓力時(shí)，增壓泵頻率越慢，流量越小，達到大輸出壓力相對困難。

Therefore, it should not be misunderstood that the driving pressure requirement 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 (low pressure of the driving gas * boost ratio=output pressure). Therefore, when designing alternative models, the appropriate boost ratio should be selected based on the on-site compressed air pressure. Normally, 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 achieve high output pressure.

提高壓力比，就可以很好地解決這種問(wèn)題。   耗氣量的要求，一般要求流量≥0.6m?/min左右，耗氣量不是一個(gè)固定值，當氣體增壓泵的負載越小時(shí)，增壓泵的頻率越快，負載越大時(shí)，氣體增壓泵的頻率越慢，當達到大輸出壓力時(shí)，氣體增壓泵停止工作，不在耗氣。空氣壓縮機的選擇上，7.5kW的空壓機配套200L以上的氣罐，是讓氣體增壓設備正常工作的低要求。

Increasing the pressure ratio can effectively solve this problem. 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, a 7.5kW air compressor paired with a 200L or more air tank is a low requirement for the normal operation of gas boosting equipment.

氣動(dòng)增壓泵分氣體增壓泵和液體增壓泵，空氣增壓泵，氣體增壓泵適合于潔凈的壓縮空氣、高純氣體的增壓，氣液增壓泵適用于水、液壓油、煤油等雜質(zhì)較少、粘稠度低的液體，空氣增壓泵可以對空氣進(jìn)行增壓。不同的介質(zhì)要選用不同的密封件來(lái)確保壓力穩定，增壓迅速。

Pneumatic booster pumps are divided into gas booster pumps and liquid booster pumps, air booster pumps, gas booster pumps are suitable for boosting clean compressed air and high-purity gases, gas-liquid booster pumps are suitable for liquids with less impurities and low viscosity such as water, hydraulic oil, kerosene, etc. Air booster pumps can pressurize air. Different media require different sealing elements to ensure stable pressure and rapid pressurization.
