What are the common problems and solutions for explosion-proof mine electric locomotives?

1. There is abnormal noise in the gearbox of the mine electric locomotives. It is mainly caused by severe wear or broken teeth of the gear of the reduction box, and loosening of the fixing screws of the gear box. Therefore, we need to replace the gears in time and tighten the fixing screws of the gearbox.

2. The mine electric locomotives can only run in one direction, not in both directions. The main reason is the poor contact between the commutator contact and the electric board or the wire and the terminal. Therefore, the contact connecting wire needs to be replaced.

3. It is caused by damage to the bearing of the shaft or lack of oil. Solution: Replace the bearing and add lubricating oil on time.

4. The braking distance of the mine electric locomotives is too long to meet the requirements. Environmentally, there is water, mud, etc. on the track contact surface, or the track has a steep slope. Therefore, it is necessary to keep the track clean and reduce the slope of the track. In operation, it is caused by the driver operating the electric locomotive at too fast speed, improper braking and improper operation. Therefore, it is necessary to regulate the operation of the driver.

5. The mine electric locomotives is off the track. The main reason is that the track sleepers are broken and the spikes fall off. Solution: add spikes and replace sleepers.

The above are the common faults and solutions of mine electric locomotives.
