Side dumping mine car is mainly suitable for excavation, construction, simple supporting, and efficient slag transportation equipment in metallurgical, mining, coal mining, railway, highway tunnels, underwater culverts, underground mining alleys, and military culverts. The side dump mining car is driven by a tractor and winch, and can be combined with a rock drill, vertical claw rock loader, and ore slide gate discharge system for loading. The ore block size does not exceed 600mm, and according to the load capacity of the mining car, the loading is led to a dedicated curved rail unloader (with a running speed of no more than 1m/s) by traction power.
What happens when a side dumping mine car experiences excessive temperature during use? The mining car manufacturer analyzed the reasons for the high temperature of the mining car as follows:
1. When the load of the side dumping mine car motor exceeds the rated value for a long time, it is difficult for the motor to start. After startup, it quickly heats up, causing all edges of the motor to descend.
2. The air-cooled motor has poor ventilation, damaged blades, insufficient heat dissipation, blocked ventilation channels, and blocked air intake network, resulting in difficulty in air intake.
3. Insufficient cooling water for the water-cooled motor, blockage of the water circuit, or long-term generation of scale in the water circuit can reduce the cross-sectional area of the motor water circuit, resulting in insufficient cooling water. The hot motor should be cooled in a timely manner.
4. The reasons for the overheating of the bearings of the side dumping mine car include uneven and unclean lubricating oil, insufficient or excessive oil supply, resulting in poor bearing lubrication.
5. After replacing the stator or rotor components, the gap is uneven, causing friction between the iron cores, causing the temperature of the motor to rise and the edges to drop.
