Common Wear Of Underground Mining Electric Locomotive

Battery locomotive is a mining equipment with short wheelbase, small turning radius, fast speed and high traction. It is used to haul transport trucks and to transport minerals, equipment and personnel. It should be noted that this type locomotive is not explosion-proof, so it can only be used in general mines and mines and hazardous locations where there is no danger of explosion.

1. Underground Mining Locomotive Mechanical wear: the wear caused by mutual scraping and grinding due to the micro unevenness of the friction surface, which is called mechanical wear.

2. Electric Locomotive Abrasive wear: the wear caused by scraping of hard particles between friction surfaces is called abrasive wear.

3. Electric Locomotive Adhesion wear: under the working condition of heavy load, due to the poor lubrication between the friction surfaces, the unit pressure is too large, and the high friction speed, a large amount of friction heat is generated in the friction pair, which is too late to be dissipated, and then these heat is transmitted to the deep inside of the parts. The high temperature softens the material and even melts and fuses the particles at individual contact points. Due to molecular gravity, these melted particles adhere from this friction surface to another friction surface. When the welding strength exceeds the internal strength of the material, deep tearing will occur, resulting in severe wear, making the friction surface more rough and uneven.

4. Electric Locomotive Fatigue wear: for the friction pair working under the condition of alternating load, the surface deformation changes repeatedly, resulting in the surface cold work hardening or microcracks, and finally the surface metal peeling off, which is called fatigue wear.

5. Locomotive Corrosion and wear: divided into chemical corrosion and electrochemical corrosion.
