Diaphragm couplingThe reasons for abnormal noise may be as follows:
1. 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 the stranded bolt is worn out, causing abnormal noise;
2. 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;
3. When the speed of the active end and the passive end are different, it will cause vibration and abnormal noise when the equipment is running;
4. The speed code disc of the motor is faulty, causing the speed of the motor to be fast and slow, and the diaphragm coupling makes abnormal noise.
