Is a coal mining of coal mine machinery, transport, transport the self-lubricating bearings for large mechanical equipment, including mining machine, conveyor, oil bearing equipment, mine excavating underground auxiliary transportation, vehicle equipment, copper mine winch, ventilation and dust removal equipment, coal washing equipment, cranes, special vehicles, etc.His demand is big, of the bearing quality also want to have a lot of requirements.So in the process of buying bearings must pay attention to the characteristics of coal mine machinery and equipment.
In coal mine production machinery and equipment has the following features:
1, poor working conditions, equipment, time is surrounded by dust, moisture and harmful gas.
2, under harsh conditions, most of the mechanical equipment is in high speed, overload, vibration, impact, friction and corrosion medium under the working conditions of the job;
3, long running time, most of the mechanical equipment day and night, long continuous operation;
4, and the bad lubrication condition, because of the bad environment, harsh working conditions, and down time is short, this makes the mechanical parts can not get the good lubrication and maintenance.
As a result, the staggering economic lost every year, only by choosing the correct bearing, regular maintenance, maintenance in time, improve the quality of maintenance, to ensure that all production equipment in a good condition to run, is to reduce coal mine mechanical wear, extend its service life, high-yield, efficient and safe production of coal and effective measures.
