Induced draft fan Simple packing manufacture and installation in the factory using the induced draft fan, because the media changes to transport gas with a pungent odor, and therefore need to install the shaft hole housing a simple seal to prevent gas leakage, the following 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 diameter 65mm deep 6- 8mm groove at its edge with two rings 6mm drill hole 4, uniform, and threading. If the cabinet is not a 35mm shaft hole Henan fan, can be adjusted as appropriate, based on the above ring size machining dimensions. Second, the installation: Remove the induced draft fan impeller, bearing housing, remove the shaft from the housing Henan custom drawing fan in the chassis of the shaft hole on a ring welding. Reinstall the drive shaft after another set in the fan, and then wrapped in oil-soaked packing groove Henan large fan, with another ring pressed, then bolted. For Boiler Fan Selection to be a brief introduction to blower resistant ceramic processing: wear blower fan design uses a new technology, ceramic - metal composite manufacturing technology, polymer composite ceramic technology, vacuum paste technology, cold welding and gas protection welding technology and NDT techniques Henan price induced draft fan, the surface layer makes the product has the most advanced technology. Wear-resistant ceramic fan and the fan impeller means the main flow components, including the site of serious wear and tear of composite fan impeller, volute, inlet and outlet, adjusting damper and piping systems, wear-resistant ceramic layer, while taking advantage of three origins theory of the impeller and the casing shape to optimize the design after the formation of a highly wear-resistant fan equipment or new features.
