We need to do maintenance on the motor in the process of using the motor, ABB motor maintenance to pay attention to environmental protection, and shall not use the method of fire to remove the motor coil.
Use more than one year ABB motor, maintenance to check the motor end cover outside the oil seal, shaft seal ring, junction box seat, junction box cover on the rubber parts such as sealing ring whether cracking, deformation, serious wear, and aging phenomenon, can not reach the sealing performance and requirements of the pieces to be replaced in a timely manner, the next brief explanation for everyone, I hope it will help you.
1, the use environment should always be kept dry, the surface of the motor should be kept clean, and the air inlet should not be obstructed by dust, fibers, etc.
2、When dismantling the motor, it is fine to remove the rotor from either the shaft extension end or the non-extension end. If there is no need to remove the fan, it is more convenient to take out the rotor from the non-extended end. When pulling out the rotor from the stator, damage to the stator winding or insulation should be prevented.
3, when the motor thermal protection continuous action, should identify the fault from the motor or overload or protection device calibration value is too low, eliminate the fault, before putting into operation.
4、It should be ensured that the motor is well lubricated during the running process. In general, if the motor runs for about 5000 hours, the grease should be replenished or replaced, and if the bearing is found to be overheated or the lubrication deteriorates, the grease should be changed in time. When replacing the grease, the old lubricating oil should be removed and the oil groove of the bearing and bearing cover should be washed with gasoline, and then the ZL-3 lithium base grease should be filled with 12 (for 2 poles) and 23 (for 4, 6 and 8 poles) of the cavity between the inner and outer rings of the bearing.
5, when the bearing life end, the vibration, and noise of the motor operation will increase significantly, check if the radial clearance of the bearing reaches a certain value, that should replace the bearing.
6, when replacing the winding must be written down the original winding form, size and number of turns, wire gauge, etc., when lost these data, should be requested from the manufacturer of ABB motors, arbitrarily change the original design of the winding, often make the motor a certain or several performance deteriorations, or even unusable.
The above is ABB motor maintenance considerations, based on the global ABB Group shared technical resources, based on 120 years of experience in the manufacture of motors and generators, ABB motor services can provide you with value-added and optimize the cost of ownership of services.
