The centrifugal fan machinery industry has many good long-term congenital favorable conditions, the market potential is quite large, and the development prospect is extremely broad. From an international perspective, peaceful development cooperation is the mainstream of the times. The overall international environment is conducive to China's peaceful development and construction. The international market has a relatively large demand for Chinese centrifugal fan products. From a domestic perspective, the in-depth development of internationalization such as urbanization, industrialization, marketization, and informatization, and the rapid growth of economic structural transformation, especially China is currently in the process of expanding domestic demand and accelerating infrastructure construction and industrial transformation and upgrading. At this stage, there is a very large market demand for advanced fan mechanical equipment.
Centrifugal fans are a very common device. You may see centrifugal fans on many occasions. For example, ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; grain Drying and delivery; you can see the style of centrifugal fans in the wind tunnel wind source and hovercraft inflation and propulsion. Centrifugal fans are a universal device. Our great ancestors started using this device long, long ago. The centrifugal fan we use today is actually an improved device of the previous fan. In the past, our ancestors did not have today's advanced industrial level. Many parts are made of wood, which made the power of the previous fan too low, and it could not play the main function of the fan at all.
Foreign centrifugal fans continue to develop new types of gas valves that operate under variable operating conditions, greatly improving the life of the valves; and to develop centrifugal fan thermodynamics, dynamics accounting software, and its operating process simulation software to improve accounting accuracy, Inductive simulation model is used to guess the functional parameters of the machine under practical working conditions, in order to improve the success rate of new product development, and strengthen the mechatronics. Compared with such high-skilled wind turbines abroad, there are many areas for improvement of domestic wind turbines. Most of the domestic product development is drawing on foreign products, the processing equipment and technology level are relatively backward, the processing accuracy is low, the output power is low, and the serialization and generalization of products are not high. Although there are many problems exposed by the equipment, these problems can be overcome. After overcoming these problems, China's fan technology will take a big step.
Fans have been used for a long time now. Moreover, the technological content of the fan itself has also increased with the continuous use of fans and the increasing needs of users, but despite this, some problems in the fan industry cannot be easily ignored, and the type of fans has gradually increased with the needs of society. It has become very broad. If the fans are classified in detail, there are seven major categories that can be subdivided. Centrifugal compressors, axial flow compressors, centrifugal blowers, roots blowers, centrifugal fans, axial flow fans and Yeats blowers are the types of fans that have been accepted by all walks of life. Many companies consider fans The development of the company has taken shape, and no breakthrough can be found to continue to innovate, which is greatly wrong. Any kind of equipment will continue to change with the development of society, and fans are no exception.
