Tips: What causes abnormal noise in the diaphragm coupling?

The gap between the two halves of the coupling is too wide, causing the diaphragm to receive a large axial force, and the stranded hole or stranded bolt is worn out, causing abnormal noise.
Excessive axial offset or too large deflection angle of the two halves of the coupling will also cause vibration and abnormal noise during equipment operation.
When the speed of the active end and the passive end are different, it will also cause vibration and abnormal noise during the operation of the equipment.
The speed code disc of the motor is faulty, which causes the speed of the motor to be fast and slow, and the diaphragm coupling makes abnormal noise.
