Repair and maintenance of motor: disassembly sequence of explosion-proof motor

Explosion-proof motor in the process of operation sometimes there will be some faults, it needs to repair and maintenance of the motor, is the need to remove the explosion-proof motor for testing and handling errors, so convenient motor should be how to remove?What is the order of disassembly?Next, I will explain to you:

Disassembly of explosion-proof motor

Preparation work before the disassembly of explosion-proof motor: first, put labels on key parts and wiring places such as motor wire head, junction box, end cover and brush grip, so as to facilitate identification.At the same time, these parts and threads are inspected and tested.

Disassembly sequence and method of explosion-proof motor:

1. First, cut off the explosion-proof motor power supply, disassemble the connection line between the explosion-proof motor and the power supply, and then do insulation treatment for the power supply to avoid electric shock.

2. Loosen belt pulley and motor coupling, and then loosen all anchor bolts and grounding bolts.

3. Remove the coupling and belt pulley, and then remove the fan cover and fan. If there are any accumulated dust in the fan cover and fan blade, it shall be cleaned in time.

4. If the explosion-proof motor belongs to the wound type motor, the brush rack and key components such as brushes and lead wires can be first lifted and removed.

5. Disassembly sequence of end cover and outer cover: remove the outer cover of the front bearing, the front end cover, the outer cover of the rear bearing and the rear end cover.

6. Take out the main part of the rotor, keep the inside of the rotor clean and avoid any bump.

7. Check whether the bearing of explosion-proof motor is intact.Then remove the front bearing - front bearing inner cover - back bearing - back bearing inner cover.

Conclusion: the disassembly sequence of explosion-proof motor is very important, and it is better to detect and troubleshoot faults for each disassembly, so as to ensure the normal operation of explosion-proof motor after maintenance and treatment of faults.
