    Tips: How to Maintain Explosion Proof Motor?

    1. When the motor is disassembled, all bolts, brush holders, pad irons, etc. must be marked. The explosion-proof motor must protect the explosion-proof surface.

    2. When disassembling (pumping) the motor rotor, the steel wire rope used should not touch the rotor, bearing, fan, oil ring and coil; the rotor should be placed on the hard gasket; special care should be taken not to make the rotor touch the stator; the steel wire rope should be used to tie the rotor The part must be lined with wooden mats.

    3. When inspecting and repairing the stator, use compressed air to blow the vent and coil ends clean. In order to avoid damage to the insulation, metal tools must not be used when removing dirt on the stator coil, and chips made of wood or insulating plates must be used.
