Air blower to work outside, because the protective measures are not in place, especially in the event of heavy winds or heavy rains, the motor is very likely to be damp or influent. At this time, the insulation resistance of the air blower drops rapidly or there is no insulation. If it is not handled in time, it is easy to burn the motor and cause electric shock.

The air blower should be removed and the power cable of the motor should be wrapped. The motor coupling, hood, fan blades and front and rear end covers should be removed, the rotor should be taken out, the air blower bearing cover should be opened, and the air blower bearing should be cleaned with gasoline or kerosene. Fuel the air blower bearing. The amount of lubricant in general: 2 pole motor is one-half of air blower bearing, 4 and 6 pole motor is two-thirds of air blower bearing, not too much, the lubricant used in air blower bearing is calcium sodium grease High speed butter. Check the stator winding. Use a 500 volt megger to check the insulation resistance between the phases of the winding and the relative ground. If the insulation resistance is less than 0.5 megohm, the stator winding must be dried.揩 Wash clean, if the insulation of the winding has been aging, the stator winding should be preheated, then brushed with insulating varnish and then dried.
