The air volume of centrifugal fan in power station can make it work better, and it can also help users reduce energy consumption. When using the fan, we should pay attention to the control of the air volume, so that the real value of the fan can be realized and the ventilation and ventilation can be well reflected.
Before we understand the control of air volume, we need to know some principles of centrifugal fan in order to help users control air volume better. According to the principle of converting kinetic energy into potential energy, the centrifugal fan of power station uses the high-speed rotating impeller to accelerate the gas, then slows down, changes the flow direction, and converts the kinetic energy into potential energy.
In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, and then changes into a radial direction when the gas flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of the flow and slows down, which converts kinetic energy into pressure energy. The pressure increase mainly occurs in the impeller, followed by the pressure expansion process. In the multistage centrifugal fan, the air flow is used to enter the next impeller, resulting in higher pressure.
The impeller of centrifugal fan in power station is a kind of energy saving measure, which can ensure that it can use the same electric energy while improving efficiency. Impeller can improve the working efficiency of centrifugal fan has two advantages, one is the diameter of impeller, the other is the tilt degree of impeller.www.jnblower.com
