Analysis on emergency treatment of mechanical equipment vibration

Generally speaking, the main cause of motor vibration failure is the asymmetrical installation of the rotor during the assembly of the motor, or the uneven and unstable voltage between the rotor and the stator. When the motor runs for a long time, the rotor core and the shaft are prone to loosening. The rotor is prone to cracks between the two under the action of magnetic pulling force, causing the rotor to loosen the shaft system during the friction process of high-speed rotation, and the motor produces vibration failure. When the vibration intensity value exceeds the allowable range when the motor is running, the motor will vibrate strongly, accompanied by loud noise. If it is allowed to develop at this time, it will cause problems such as burning of the motor coil, short circuit of the motor, and serious bearing wear.
