5. Sound abnormality during operation of explosion-proof motor
possible reason:
1. Phase loss operation
2. Rubbing foreign objects on the rotor or rotor and rubbing against the stator or other fixtures
3. Bearing damage or severe oil shortage
4. Wave washer break
5. Centrifugal switch is damaged
6. Axial yaw is too large
Approach:
1. Check the components of the circuit to troubleshoot
2. Check if there are any protruding foreign objects in the stator and the rotor, and if the bearing chamber is too worn
3. Cleaning the bearing, adding rust grease
4. Replace the wave washer
5. Repair or replace the centrifugal switch
6. Adjust the axial movement
Sixth, the explosion-proof motor stops, does not turn after the power is turned on, and can start after the meeting time
possible reason:
Winding short circuit
2. Overload
3. Thermal protector action
Approach:
1. Repair the winding
2. Check the transmission part and working machine to troubleshoot
3. The thermal protector operates after overheating or overcurrent, and resets after cooling
