Induced draft fan Simple packing manufacture and installation in the factory using the induced draft fan, because the media changes Hebei saving fan, to transport gas with a pungent odor induced draft fan, so need to install the shaft hole housing a simple seal to prevent gas leakage below to packing, for example, a brief introduction: a manufacturing: the fan casing on the lead axle hole diameter of 35mm, for example; 16-18mm diameter 75mm inner diameter of 35mm thick steel ring were two middle Car 6-8mm diameter 65mm deep groove at its edge with two rings 6mm drill hole 4 Xinjiang induced draft fan power, uniform, and threading. If the cabinet is not a shaft hole 35mm, the ring can be adjusted on the basis of the above dimensions processing size appropriate. Second, the installation: Remove the induced draft fan impeller, bearing housing, the shaft is removed from the enclosure, the enclosure will be a ring on the shaft bore welding. Reinstall another set on the drive shaft to the furnace blower Anhui fan, then oiled packing wound in the groove, with another ring pressed, then bolted. The structure of the induced draft fan and induced draft fan mainly by the use of blades, shutters, window mechanism, motors, pulleys, into the hood, in the framework, chassis, safety nets and other components. When the boot is rotated by the motor-driven fan, ventilation and window blinds open institution. Automatic shutdown shutters closed. Fans are widely used in factories, ventilation mines, tunnels, cooling towers, vehicles, ships and buildings, dust emission and cooling; boiler and industrial furnace ventilation and the wind; air-conditioning equipment and household appliances cooling and ventilation equipment ; grain drying and sending; wind tunnel source and inflatable hovercraft and propulsion. Inner-proof fan, fan, fan nagorye provided by the Shanxi nagorye blower limited liability company. Shanxi nagorye Blower Co., Ltd.
