Application of Bearings in Coal Mining Equipment
Coal mine machinery and equipment is a kind of large-scale machinery and equipment specially used in coal mine excavation, transmission and transportation, including mining machines, conveyors, tunnel excavation equipment, underground auxiliary transportation, vehicle equipment, mine winches, ventilation and dust removal equipment, and coal washing. equipment, cranes, special vehicles, etc.
The mechanical equipment in coal mine production has the following characteristics:
1. The working environment is harsh, and the equipment is always surrounded by dust, water vapor and harmful gases;
2. The working conditions are harsh, most of the mechanical equipment works under the working conditions of high speed, heavy load, vibration, shock, friction and medium corrosion;
3. The running time is long, and most of the mechanical equipment works continuously for many years, day and night;
4. Poor lubrication conditions. Due to the harsh environment, harsh working conditions, and short downtime, the mechanical parts cannot be well lubricated and maintained.
Therefore, the annual economic loss is staggering. Only by selecting the correct mining bearings and supply, performing regular maintenance, timely maintenance, improving the maintenance quality, and ensuring that all production equipment is running in good condition, can the wear and tear of coal mine machinery be reduced and its use extended. Longevity, effective measures to achieve high coal yield, high efficiency and safe production, mining operators can ensure high productivity and make equipment reach the expected service life.
There are many types and models of construction machinery and equipment, the main types are: forklifts, shovel transport machinery, compaction machinery, concrete machinery, etc.
Many modern large-scale construction machinery, such as asphalt mixing equipment, stabilized soil mixing equipment, combined crushers, etc., are large in scale, and the mass of each part is tens to hundreds of tons, and most of the construction machinery is used in sediment, gravel, rainwater, etc. When working in harsh environments such as wind and snow, its technical condition will inevitably decline faster than other machines, and the cooperation between parts will appear to be loose, worn, corroded and scaled to varying degrees. Relationships and institutional work coordination will be affected to varying degrees, resulting in a decline in performance indicators such as power, economy, and reliability, and even machine accidents.
Therefore, attention must be paid to the selection and technical maintenance of parts, especially mining equipment bearings. A high-performance bearings for mining machinery can improve the working life of mining machinery and improve work efficiency, thereby improving economic benefits.
Mining machinery and engineering machinery are mostly located in areas with complex terrain and need to carry out difficult mechanical operations, which requires high requirements for mining equipment, such as crusher, drilling rig, excavator, etc. The normal implementation of these devices requires a large number of professional and high-quality mining bearings.
The bearing bears all the load of the machine, so good lubrication has a great relationship with the bearing life. It directly affects the service life and operation rate of the machine. Therefore, the injected lubricating oil must be clean and the seal must be good. Therefore, users want to buy strong, durable and highly reliable bearing products that can withstand harsh conditions.
