With the advance of China's industrialization process, industry is making great efforts to save energy, industrial upgrading and consolidation and restructuring, industry infrastructure requires significant updating. Centrifugal fans as an important industrial equipment, will be more used in electric power, cement, petrochemicals, coal, mining, and environmental protection and other fields. Under the new situation of economic development, future centrifugal fans will continue to maintain a rapid growth of the industry. By 2012, centrifugal fan industry market will reach 46 billion yuan.

Centrifugal fan is essentially a variable flow constant pressure device. When speed is constant, the pressure-flow theory of centrifugal fan curve is a straight line. because of the internal damage, the actual characteristic curve is bent. Centrifugal fan produces pressure in the intake air temperature or density of greater impact. For a given intake and maximum intake temperature (air density minimum) when the lowest pressure. for a given pressure and flow characteristic curve, there is a power and flow characteristic curve. when the fan runs at a constant speed, for a given flow, required power increases with the decrease of air temperature.
