Bearing in Coal Industry
Coal mining machinery equipment in coal mine is a mining, transmission, self-lubricating bearings for large-scale machinery and equipment transport, including mining machines, conveyors, mine Digging oil-bearing equipment, underground auxiliary transport, vehicle equipment, mine copper sleeve winches, ventilation and dust removal equipment, coal washing equipment, cranes, special vehicles. He is also a great demand for bearings, but also has a great quality requirements. So in the process of buying bearings must pay attention to the characteristics of coal mining machinery and equipment.
Mine production of machinery and equipment has the following characteristics:
1, poor working conditions, equipment is always surrounded by dust, moisture and harmful gases being;
2, harsh working conditions, most of the machinery is working at a high speed, heavy load, vibration, shock, friction and corrosion media and other working conditions;
3, long-running, most of the mechanical equipment day and night, over many years of continuous operation;
4, poor lubrication conditions due to the harsh environment, harsh working conditions, plus the downtime is short, which makes mechanical parts are not good lubrication and maintenance.
Thus, the annual economic losses caused by staggering, only by choosing the correct bearing, regular maintenance and timely maintenance, to improve the quality of maintenance to ensure that all equipment running in good condition, is to reduce the mining machinery wear and prolong its use life, high production efficiency and safety of coal production and effective measures.
