Problems solved by technology

[0003] Centrifugal fans are often used in the process of environmental protection coating. Centrifugal fans can immediately discharge the polluted gas generated in the process of environmental protection coating to prevent pollution. However, most modern centrifugal fans have many defects. For example, the shaft disk of modern centrifugal fan is not fixed very firmly and is often damaged. At the same time, the centrifugal fan will generate large mechanical vibration when it is working. On the one hand, the mechanical vibration will generate large noise. Loosen parts inside the device, and also cause damage to the fan

Description

technical field [0001] The invention relates to a fan, in particular to a special centrifugal fan for environmental protection coating. Background technique [0002] Fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Modern fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Ventilation , Dust extraction and cooling, ventilation and induction of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grain, wind tunnel wind source and inflation and propulsion of hovercraft, etc. [0003] Centrifugal fans are also often used in the process of environmental protection coating. Centrifugal fans can immediately discharge the polluted gas generated in the process of environmental protection coating to prevent pollution. However, most modern centrifugal fans have many defects. ...
