Since centrifugal fan was invented and applied in mine ventilation field, centrifugal fan has gradually become the auxiliary equipment of production enterprises. Under the impetus of technology, the types of centrifugal fans are more and more, the structure is more and more perfect, and the application is naturally more and more extensive.
From the point of view of the structure of centrifugal fan, there is no particularly complex principle, mainly under the action of mechanical energy, to improve the gas pressure in the body, and then achieve the purpose of gas discharge. Centrifugal fan, as a fluid machinery, has been widely used in various industries.
In the factory workshop, the centrifugal fan ventilation is particularly important, and the improvement of the working environment further ensures the health of the staff. In warehouses, centrifugal fans can ensure the drying of air and the protection of industrial products from the erosion of moisture in the air.
In mine and tunnel, the importance of centrifugal fan is irreplaceable. It promotes the circulation of air and the discharge of dust, and ensures the efficient operation of mine. Ships, buildings and automobiles are also potential markets for centrifugal fans. The equipments of centrifugal fans improve the environmental indicators of vehicles, buildings and ships, which can not be ignored for improving the added value of such products.
In agricultural production, centrifugal fan plays an important role in grain drying and screening. In the field of power generation and metallurgy, centrifugal fans are needed to induce and supply air to boilers, blast furnaces. On the one hand, the working environment inside the furnace should be guaranteed. On the other hand, oxygen with high oxygen content should be supplied to blast furnaces and boilers, so as to increase firepower, save energy consumption such as coal and reduce costs. However, considering that the temperature of these environments is higher than 200 degrees Celsius in general, the requirement for centrifugal fans is also higher.
