Induced draft fan Simple packing manufacture and installation in the factory using the induced draft fan, because the media changes induced draft fan, to transport gas with a pungent odor, and therefore need to install the shaft hole housing a simple seal to prevent gas leakage below as an example of Shanxi packing pipe fan, a brief introduction: a manufacturing: the fan casing on the lead axle 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, 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, remove the drive shaft in Shanxi pressure induced draft fan from the housing, the housing shaft hole on a ring welding. Reinstall another set on the drive shaft fan Shanxi proof fan, then oiled packing wound in the groove, with another ring pressed, then bolted. After the induced draft fan speed can be gradually opened to normal valve until the rated operating conditions, maintenance must be de-energized when the first draft fan maintenance shutdown, the fan starts in the no-load condition, Fan timely replacement of lubricant according to the actual situation, you should check the bearing tank temperature is normal, increased vibration occurs when the fan bearing temperature is too high, the motor current is too large, which are not normal circumstances the body overheating, Fan should promptly identify the reasons for exclusion before running again after a failure.
