Maintenance Inspection and Anti-wear measures of Boiler ventilator and pulverized Coal exhaust Fan
because the concentration of the fuel particles in the fly ash or the pulverizing system in the flue gas is too large, the material of the impeller and the shell is not abrasion-resistant, the balance precision of the rotor is not high, the balance is not lost in the operation, or the manufacturing quality of the impeller is poor and the like, So that the fan, in particular, the induced draft fan and the powder discharge fan, has the problems of serious abrasion, vibration, high bearing temperature rise and leakage, and the like. Therefore, careful inspection of the fan is necessary from the following aspects.
1 Inspection of wear and tear
2 Inspection of bearings
3 Inspection of welding quality, riveting quality and deformation
4 Welding quality, riveting quality and deformation inspection
5 Balance check of rotorhttps://www.jnblower.com/
