How To Perform Maintenance For Underground Mining Trolley Locomotive

With the increase in the use of underground mining trolley locomotive, everyone also has a more comprehensive understanding of each model, and also knows that if you want to adapt to the environment in a coal mine, the performance of the locomotive must be good, but what we need to pay attention to is that as mechanical equipment For a long time, it will cause the efficiency to drop. We must perform maintenance normally, so next, let ’s take a look at how to perform maintenance on underground mining trolley locomotives.

1. Pulverized coal and dust should be cleaned frequently on the exterior and interior of the motor.

2. After removing the grade surface dirt, check the insulation resistance with the corresponding range megohmmeter. In the actual cold state, the insulation resistance must not be lower than 1MΩ.

3. Check the bearing grease for dirt. If there is dirt, the bearing must be cleaned with kerosene and replaced with clean No. 3 industrial lithium-based grease, whose volume occupies about 1/3 of the bearing chamber space.

4. Check whether the armature can rotate freely and there should be no left-right movement or abnormal sound.

5. Check whether the exit sign and connection of the mine overhead line electric locomotive are correct.
