Performance and development of centrifugal fan
I believe everyone is no stranger to centrifugal fans nowadays. In fact, to put it bluntly, centrifugal fans convert kinetic energy into potential energy. Because they can drive the high-speed flow of surrounding air, they are widely used in mines, industry, construction industry, drying industry and air conditioning equipment. As it is widely used, what are the performance characteristics of centrifugal fans? What will be the development trend of Dahe in the future? Next, Shanghai Yingda fan will answer for you one by one。
1、Performance of centrifugal fan
Centrifugal fan is essentially a variable flow constant pressure device. When the speed is constant, the theoretical curve of pressure flow of centrifugal fan should be a straight line. The actual characteristic curve is curved due to internal loss. The pressure generated in the centrifugal fan is greatly affected by the change of intake air temperature or density. For a given intake air quantity, the pressure generated at the highest intake air 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 operates at a constant speed, for a given flow, the required power increases with the decrease of the intake air temperature。
2、Development of centrifugal fan
With the advancement of China's industrialization process, the industrial industry is vigorously carrying out energy conservation and consumption reduction, industrial upgrading and integration and reorganization, and industrial infrastructure needs to be largely updated. As an important supporting equipment in industry, centrifugal fans will be more applied in power, cement, petrochemical, coal, mining, environmental protection and other fields. In 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 centrifugal fan industry will reach an unprecedented scale.
It can be seen that the centrifugal fan uses the characteristics of using the high-speed rotating impeller to accelerate the gas, then decelerate, change the flow direction, and convert the kinetic energy into potential energy, which makes it widely used in the industrial industry, promotes its development path, and promotes the centrifugal fan market again。
Huangshi fan independently developed SAB brand fan on the basis of absorbing advanced fan technology from Europe and America, and was grandly launched into the market in 2012. The products focus on EC fan, DC fan and AC fan. With its excellent design and careful production, Huangshi fan creates Yingda precision fan with better quality, which is applicable to the construction and matching of environmental protection, construction, metallurgy, chemical industry, power, painting and other fields。
