The most complete explosion-proof motor fault diagnosis and treatment plan
Explosion-proof motors are mostly used in places with high safety requirements such as workshops and mines, but it is inevitable that some faults will occur. In the face of some basic faults, we also need to know more solutions, so that when the explosion-proof motor fails, it can be fast. Positioning errors and solving it to ensure the safe operation of the production line, then explain the topic of explosion-proof motor fault repair:
First, the explosion-proof motor can not start
Silent
b. Vibration, abnormal sound
possible reason:
1. The power is not connected
2. Three-phase motor phase loss
3. Stator winding disconnection
4. Stator winding phase-to-phase short circuit
5. The centrifugal switch or capacitor is damaged or the circuit is blocked.
6. The transmission part is blocked or the load is too large
Approach:
1. Check whether the switch, fuse, contactor contact, circuit and explosion-proof motor lead wire are connected.
2. Check if the power supply, switch, fuse, and cable are intact.
3~4. Repair the winding
5. Repair or replace the centrifugal switch, capacitor, or check the repair connection line
6. Check and repair the transmission part, check the overload and eliminate the cause
