Nitrogen machine motor axial, the first to show the symptoms of motor vibration and noise significantly increased; as the parameters of axial displacement will change the rotor and the stator core of the power plant, gap length and so on, the situation may appear fluctuation during the process of running, timely fast and slow. Secondly, when the motor axial, axial clearance coupling the electrical and mechanical equipment connecting to the top will be dead, because the motor shaft misalignment, equipment, will cause the whole vibration equipment is intense, serious damage to equipment base and anchor bolt.
Therefore, when the motor vibration, noise and other abnormal situations occur, we must immediately stop the operation of the equipment, organize maintenance.
From the nitrogen machine motor performance, axial movement makes the stator and rotor interaction part decreases, this nitrogen machine motor load capacity will decline, moving back and forth, will make the inverter current when the inverter life, influence.
From the mechanical perspective, back and forth movement will affect the bearing life, especially at high speed nitrogen machine motor shaft makes the jump move should have binding sites for the relative motion of the gap becomes larger, the vibration and noise of the motor becomes large, "sweeping" may reduce the service life. Timely maintenance can prevent nitrogen machine motor jump, the quality of the cause of shaft jumping, can not be prevented. Avoid making the motor subject to axial force.
