Air cooling provides suitable air flow for some long-running heating equipment to achieve the purpose of cooling the equipment; heating and drying, by blowing a certain temperature of fresh air to accelerate the dehydration process of equipment, finished or semi-finished products. For example, a large number of fans may be used in the drying process of the spraying workshop of industrial products, food, pharmaceuticals, papermaking and other production lines; pneumatic conveying, through the work of the fan, the medium of not too large mass is transported to the destination through the pipeline, this purpose The ground is actually the next step in the industrial process. For example, washing powder production line, blow molding process line; air supply to support combustion, and a large amount of oxygen-containing fresh air is sent through high pressure. High temperature combustion vessels such as furnaces and converters that require high temperatures are fully burned and have sufficient calorific value to achieve the purpose. Such fans are used in steelmaking blast furnaces, sintering processes, cement manufacturing processes, and polysilicon processing processes. The fan 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.
