FAQ

1. There are three main reasons for vibration: electromagnetic reasons; mechanical reasons; electromechanical mixing reasons.
    
   Mechanical reasons
   1. The motor itself:
   The rotor is unbalanced, the rotating shaft is bent, the slip ring is deformed, the air gap between the stator and the rotor is uneven, the magnetic center of the stator and the rotor is inconsistent, the bearing is faulty, the foundation installation is poor, the strength of the mechanical mechanism is insufficient, resonance, the anchor screw is loose, and the motor fan is damaged.
   Typical case: After replacing the upper bearing of the condensate pump motor in the factory, the vibration of the motor increased, and the rotor and stator showed slight signs of sweeping. After careful inspection, it was found that the rotor of the motor was lifted to the wrong height, and the magnetic centers of the rotor and stator were not aligned. Readjust After the thrust head screw is replaced with a cap, the motor vibration fault is eliminated. After the overhaul, the vibration of the cross-line hoist motor has been too large, and there are signs of gradual increase. When the motor is dropped, it is found that the motor vibration is still very large, and there is a lot of axial movement. It is found that the rotor core is loose. , There is also a problem with the rotor balance. After replacing the spare rotor, the fault is eliminated, and the original rotor is returned to the factory for repair.
   2. In terms of cooperation with the coupling:
   Coupling damage, poor coupling connection, inaccurate coupling centering, unbalanced load machinery, system resonance, etc. The shaft system of the linkage part is not centered, the center lines are not coincident, and the centering is incorrect. The cause of this failure is mainly caused by poor alignment and improper installation during the installation process. Another situation is that the center lines of some linkage parts are coincident in the cold state, but after running for a period of time, due to the deformation of the rotor fulcrum, foundation, etc., the center line is damaged again, resulting in vibration.
   For example: a. The vibration of the circulating water pump motor has been too large during operation. There is no problem in the motor inspection, and everything is normal at no-load. After positive, the motor vibration is eliminated.
   b. After replacing the pulley of the induced draft fan in the boiler room, the motor will vibrate during the test run and the three-phase current of the motor will increase. Check all the circuits and electrical components and find that the pulley is unqualified. After the replacement, the vibration of the motor is eliminated, and the three-phase current of the motor is The current also returned to normal.
   3. Reasons for motor mixing
   1. Motor vibration is often caused by uneven air gap, causing unilateral electromagnetic pulling force, and unilateral electromagnetic pulling force further increases the air gap. This electromechanical hybrid effect is manifested as motor vibration.
   2. The axial movement of the motor, due to the gravity of the rotor itself or the installation level and the wrong magnetic force center, the electromagnetic tension caused by the axial movement of the motor causes the motor to vibrate more and more. rise rapidly.
   The gears and couplings connected to the motor are faulty. This kind of failure is mainly manifested in poor gear engagement, serious gear tooth wear, poor lubrication of the wheel, skew and misalignment of the coupling, incorrect tooth shape and pitch of the toothed coupling, excessive clearance or serious wear, which will cause certain damage. vibration.
   Defects in the structure of the motor itself and installation problems. This kind of fault is mainly manifested as ellipse journal, bending shaft, too large or too small gap between shaft and bearing bush, insufficient rigidity of bearing seat, foundation plate, part of foundation and even the entire motor installation foundation, fixed between motor and foundation plate It is not strong, the foot bolts are loose, the bearing seat and the base plate are loose, etc. Excessive or too small clearance between the shaft and the bearing bush can not only cause vibration, but also make the lubrication and temperature of the bearing bush abnormal.
   The load dragged by the motor conducts vibrations.
   For example: the turbine of the steam turbine generator vibrates, the fan and water pump driven by the motor vibrate, causing the motor to vibrate.
