Dust exhaust centrifugal fan in the process of using mainly rely on its input mechanical energy, when used in the odd-high gas pressure and exhaust gas machinery, it is a kind of driven fluid machinery. Centrifugal fans are widely used in the ventilation, drainage and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings.
Centrifugal fan dust removal of the overall installation of the unit should be placed directly on the basis of a pair of oblique horn leveling. On-site assembly of centrifugal fans, the base of the cutting surface should be properly protected, there should be no corrosion or operation, the base is placed on the basis of the application of a pair of oblique horn leveling.
Dust centrifugal fan bearing and base should be used in conjunction with the close, the vertical non-horizontality should not exceed 0.2 / 1000, measured by the spirit level on the spindle, the horizontal non-horizontal bottom should not exceed 0.3 / 1000, with the spirit level in the bearing Seat level measured on the facet.
Dust exhaust centrifugal fan bearing scraping scraping should be prior to the rotor shaft centerline and the axis of the cabinet correction, while adjusting the gap between the impeller and the inlet and the gap between the spindle and the rear plate shaft hole to make it meet Equipment technical documents. Spindle and bearing assembly, should be checked according to the provisions of equipment technical documents. Between the bearing cap and the bearing should be 0.03 ~ 0.04 mm of interference (measuring the outer diameter of the bearing and bearing the inner diameter).
Dust exhaust centrifugal fan casing in the assembly process, it should be mainly based on the rotor shaft center to find the position of the casing and the impeller air inlet and the casing inlet and the axial clearance between the high-speed high-speed To the provisions of the technical equipment within the scope of the same time, check the anchor bolts are tightened.
