Fans are mainly used in metallurgy, petrochemical, electric power, urban rail transit, textiles, ships and other fields of the national economy and ventilation in various places. As the competition in the wind turbine manufacturing industry continues to intensify, mergers and acquisitions and capital operations among large wind turbine manufacturers are becoming more and more frequent, and China's outstanding wind turbine manufacturers are paying more and more attention to the research on the industry market, especially the industrial development environment and product buyers.
General ventilation fans (usually small and medium centrifugal and axial fans) are the most widely used. Where are the common centrifugal fans and axial fans used?
Axial fans and centrifugal fans are two different products in the fan category, and their main functions are also equipment for ventilating ambient air.
It has a wide range of uses, that is, the airflow in the same direction as the axis of the fan blade, such as an electric fan, and an air conditioner outdoor fan is a fan that operates in an axial flow mode. It is called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are usually used in applications with high flow requirements and low pressure requirements. Axial fans fix the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high.
It is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Centrifugal fans are widely used in ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft in boilers and industrial furnaces; cooling and in air conditioning equipment and household appliances. Ventilation; drying and selection of grain; air source of wind tunnel and inflation and propulsion of hovercraft, etc.
With the continuous development of science and technology, people's requirements for the use of centrifugal fans are getting higher and higher. As far as the current development trend of centrifugal fan technology in foreign countries is concerned, the centrifugal fan will continue to increase in capacity, high efficiency, high-speed miniaturization and low-cost centrifugal fans. noise direction. The capacity of large centrifugal fans continues to increase.
With the large scale of various industrial installations, the required capacity of various centrifugal fans is also increasing, and large-sized centrifugal fans will increase in the market in the next few years.
