Professional Motor Maintenance Center Motor maintenance Process: Cleaning the rotor-replacement of carbon brushes or other components-vacuum F-class pressure dip paint-drying-school balance.
1, the use of the environment should be kept dry, the motor surface should be kept clean, air inlet should not be affected by dust, fiber and so on.
2. When the thermal protection of the motor occurs continuously, it should be found that the failure comes from the motor or overload or the protection device setting value is too low, after the elimination of the failure, the party can be put into operation.
3, should ensure that the motor in the process of good lubrication. General motor running about 5,000 hours, that is, should be supplemented or replaced with grease, the operation found that the bearing overheating or lubrication deterioration, hydraulic timely change grease. When replacing the lubricating grease, the old lubricating oil should be removed and the oil tank of the gasoline cleaning bearing and the bearing cap shall be filled, and then the ZL-3 lithium base grease will fill the empty cavity between the inner and outer rings of the bearing 1/2 (to 2 poles) and 2/3 (to 4, 6, 8 poles).
4. When the life of the bearing is ended, the vibration and noise of the motor will obviously increase, and the bearing shall be replaced when the radial clearance of the bearing is checked to the following values.
5. When removing the motor, the rotor can be removed from the extension end or the extension end. If it is not necessary to remove the fan, or from the shaft to remove the rotor is more convenient, from the stator to draw the rotor, should prevent damage to the stator windings or insulation.
6, the replacement of the winding must note the form of the original winding, size and turn number, wire, etc., when the data is lost, should be asked to the factory, arbitrarily change the original design of the winding, often make the motor or some of the performance deterioration, and even can not be used.
