Method for troubleshooting axial vibration of motor
1. Before the motor is not stopped, check the vibration of each part with the vibration meter. For the vibration part, test the vibration value in three aspects according to the vertical horizontal axis.
If the anchor screw or the bearing end cap screw is loose, it can be tightened directly, and then the vibration is measured to see if it is eliminated or lightened.
Secondly, it is necessary to check the three phases of the power supply: whether the voltage is balanced or not, the phase loss of the motor not only causes vibration but also causes the motor to heat up rapidly. Observe whether the pointer of the power meter swings back and forth, and the current will swing when the rotor is broken (public number: Pump butler), finally check whether the three-phase current of the motor is balanced, and find the problem and stop the operation in time to avoid burning the motor.
2. If the motor vibration is still not solved after the surface phenomenon is processed, the power supply must be disconnected to uncoupling the coupling. If the motor is vibrated, the motor itself has a problem. In addition, you can take the power-off method to distinguish between electrical reasons and mechanical reasons. When the power is cut off, the motor will not vibrate or the vibration will be relieved immediately. It means that it is an electrical cause or it is a mechanical fault to repair the fault.
