Maintenance of an industrial fan
As every rotating machine, the fans requires serious monitoring to avoid characteristics deterioration, but also to avoid breakage, sometimes dangerous for the operator or user and likely to generate direct and indirect costs.
The impeller state should be often evaluated with eventual cleaning to avoid any unbalance. The lubrication of the house bearing should be done according the frequency, the quantity and the type of grease recommended by the manufacturer. Some fans, essential for the smooth operation of the production, should be continuously monitored on the house temperature bearings and vibrations. Belts and bearings should be regularly inspected and changed while planned shutdowns, according the lifetime recommended by the supplier.
