Description
technical field [0001] The invention relates to a magnetic sealing centrifugal fan. Background technique [0002] With the advancement of my country's industrialization process, the industrial sector is vigorously carrying out energy conservation and consumption reduction, industrial upgrading and integration and reorganization, and industrial infrastructure equipment needs a large number of updates. Centrifugal fans, as important supporting equipment in industry, will be more widely used in fields such as electric power, cement, petrochemical, coal, mining and environmental protection. [0003] The centrifugal 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. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces, etc., but in s...
