In the process of using the centrifugal fan, what is worth paying attention to is the air volume. How should we adjust the air volume? Let's take a look at it together.
The first method is to change the pressure of the centrifugal fan to change the pressure, air volume and power of the fan under the premise of the characteristics of the fan pipe network system, so as to achieve the intended purpose. As the fan speed increases, the fan volume and pressure increase, and vice versa. The main advantage of this method is that there is no additional energy loss, so its economic performance is better.
The second method is to change the characteristics of the pipe network system by adjusting the throttle valve or changing the opening degree of the card. In this adjustment case, the air volume is inversely proportional to the pressure and is also related to the degree of opening of the throttle or insert.
