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.
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.
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.
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.
