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.
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.
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.
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.
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.
