Performance and Development of Centrifugal Fan
1. Performance of centrifugal fan
The centrifugal fan is essentially a variable flow and constant pressure device. When the rotational speed is constant, the pressure-flow theoretical curve of the centrifugal fan should be a straight line. The actual characteristic curve is curved due to internal losses.
The pressure developed in a centrifugal fan is greatly affected by changes in inlet air temperature or density. For a given intake air volume, the highest intake air temperature (lowest air density) produces the lowest pressure. For a given pressure versus flow characteristic curve, there is a power versus flow characteristic curve. When the blower is running at a constant speed, for a given flow, the required power increases as the intake air temperature decreases.
2. Development of centrifugal fans
With the advancement of my country's industrialization process, the industrial industry is vigorously carrying out energy conservation and consumption reduction, industrial upgrading, integration and reorganization, and industrial infrastructure equipment needs to be updated in large quantities. As an important supporting equipment in the industry, centrifugal fans will be more used in electric power, cement, petrochemical, coal, mining and environmental protection fields.
Under the new economic development situation, the centrifugal fan industry will continue to maintain rapid growth in the future. In the future, the market scale of the centrifugal fan industry will reach an unprecedented scale.
It can be seen that the centrifugal fan uses the high-speed rotating impeller to accelerate the gas, then decelerates and changes the flow direction, so that the kinetic energy is converted into potential energy, so that it is widely used in the industrialization industry and promotes its development. The market for wind turbines has been boosted once again.
