The driving air pressure is generally 3-8 bar (0.3-0.8 MPa), but of course, it is not within this pressure range. The boosting effect of the same booster pump is consistent. The boosting ratio of the same booster pump (driving pressure, plug to boost pressure, and plug area ratio) is fixed. The maximum output pressure at the driving air pressure of 3 bar is inconsistent with that at the driving air pressure of 8 bar. Therefore, do not misunderstand it as the driving air pressure requirement of 3-8 bar, which means that the same pressure can be reached within this pressure range. Therefore, when selecting, the appropriate pressure ratio should be selected based on the pressure of the compressed air on site, and generally, there should be 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.
The principle is that the large piston drives the small piston, and the piston moves back and forth to achieve pressure increase. As the pressure at the outlet increases, the forces at the two ends of the large piston, plug, and small piston tend to balance. Therefore, the frequency of the booster pump movement decreases and the flow rate decreases. When the pressure at the outlet is the boost ratio of the booster pump, the force values at both ends are balanced, and the booster pump stops working. The flow rate is 0. Once the pressure at one end drops, the booster pump will automatically work to make up for the pressure, Equipped with automatic pressure maintaining and replenishment functions.
The requirements for air consumption generally require a flow rate of about 1m3/min, and the air 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 air. It is not recommended to use an air compressor with a 220V power supply. A 220V air compressor generally has a smaller displacement, and the booster pump cannot perform normally.
