Performance and development of centrifugal fans

1. Performance of centrifugal fans
Centrifugal fans are essentially a variable flow constant pressure device. When the speed is constant, the pressure-flow theoretical curve of the centrifugal fan should be a straight line. Due to internal losses, the actual characteristic curve is curved. The pressure generated in the centrifugal fan is greatly affected by the change of the inlet temperature or density. For a given inlet volume, the pressure generated at the highest inlet temperature (lowest air density) is the lowest. For a given pressure and flow characteristic curve, there is a power and flow characteristic curve. When the blower runs at a constant speed, for a given flow, the required power increases as the inlet 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, carrying out industrial upgrading and integration and restructuring, and industrial basic equipment needs to be updated in large quantities. Centrifugal fans, as important supporting equipment for industry, will be more used in power, cement, petrochemical, coal, mining and environmental protection. Under the new economic development situation, the centrifugal fan industry will continue to maintain rapid growth in the future. In the future, the market size of the centrifugal fan industry will reach an unprecedented scale.
It can be seen that centrifugal fans use the characteristics of high-speed rotating impellers to accelerate the gas, then slow down and change the flow direction, so as to convert kinetic energy into potential energy. This has led to its widespread use in industrial industries, promoted its development path, and given the centrifugal fan market a boost once again.
