Causes and solutions of motor sweep
During operation, once there is a problem with the machine sweeping the chamber, the motor will generally stop rotating, and in severe cases, the motor will burn out. Here we will introduce the causes of the motor sweeping the chamber, as well as the repair methods for common motor sweeping failures.
Causes of motor sweep
Common causes of motor sweep are summarized as follows:
1. The motor bearings are seriously worn, or the bearings are damaged. During the operation of the motor, the bearings shake too much, and the problem of sweeping the chamber occurs.
2. The rotor shaft of the motor is severely bent. During the rotation process, it will rub against the casing, causing a sweep failure.
3. If the motor end cover is not installed properly, or the positioning pin is broken, and the motor end cover is installed off-center, the problem of sweeping the chamber will also occur.
4. Foreign matter in the gap between the stator and rotor of the motor is relatively rare, but if it occurs, it will cause the problem of motor sweeping.
Repair methods for motor sweep
For motors with bearing rotating sleeves, do not use the chiseling method to repair the motor bearings . Instead, use the gluing method to repair the motor bearings, which will have better results.
Suggestions: (1) Power
Metal glue for larger motors with higher speeds;
Maintenance method: first clean the rotating sleeve, add grease , then apply glue, and then reinstall the motor. For serious rotary sleeves, where the gap between the inner ring of the bearing and the journal or the outer sleeve and the end cover is large, a metal sheet of appropriate thickness can be used to pad the gap. In order to ensure concentricity, the metal sheet should be made into a bevel, and appropriate glue should be applied to the motor bearing gap to return to normal.
