Lubrication is the main purpose of establishing liquid friction on the friction surface of mechanical parts, the liquid friction will greatly reduce the mechanical friction, lighten the mechanical wearing, improve the efficiency and extend the service life of machine. In this text, we will introduce the lubrication method and application of mining crusher equipment.
1. Hand lubrication
Hand lubrication is mainly used for exposed gears, chains, slow sliding wheel shaft and other rough machinery with regular lubrication. This lubrication device is simple, typically used for light load or low speed friction parts.
2. Dropping lubrication
It is mainly used for rolling and sliding bearings, chain, guide rail, pump and air compressor machine.
3. Oil pool lubrication
It is mainly used in closed gear box, internal combustion engine, air compressor equipment, etc. The lubrication method can only be used for enclosed machine parts without any maintenance, the lubrication is very reliable, only need to keep the oil level. The sealed lubrication can prevent pollution. Also it is circulation lubrication, so it can not only save oil but also prevent oil leak.
4. Chain and ring lubrication
It is mostly used for spindle bearings of motor, ventilator, hoisting pulley, water pump, etc. This kind of lubrication method can only be used for horizontal spindle.
5. Wick and pad lubrication
The lubrication method uses thin glass tubes and siphon of wick and oil pad to supply oil on the friction surface. After a certain usage period of time, it needs to clean up. Oil supply of this method is uniformly continuous, but supply amount cannot adjust.
6. Force-feed oil lubrication
It is mainly used for air compressor, internal combustion engine, steam engine, metal cutting machine, etc. The lubrication device is complex, but it is clean and reliable. Lubrication oil supply can be adjusted by the plunger stroke, oil supply is uniform, not continuous.
7. Oil mist lubrication
The oil mist lubrication method is mainly used in high-speed rolling bearings and enclosed gears, chains, skateboarding, guide etc. Oil mist lubrication device makes the lubrication oil sprayed from the nozzle by the compressed air, and then atomization into the friction surface, and make it precipitated in the saturated state, then let the thin layer of oil film adhered to the friction surface to ensure the lubrication. The amount of oil can be adjusted.
8. Pressure circulation lubrication
The pressure circulation lubrication device is mainly used for mine hoist, air compressor and some metal cutting machine tools and mechanical equipment of the reducer. Because the oil is used by cycle, and can be uniformly continuous oil supplying. For all kinds of friction surfaces with large load, high speed and more heating, this method is most effective.
9. Centralized lubrication
The centralized lubrication is mainly used for mine multi rope friction hoist and rolling mill equipment with a large number of lubrication points. For this lubrication system, the small one can be used in a single device, larger one can be used for the whole automatic lubrication system in the workshop. The lubrication method can be manual operation, also can be automatically distributed oil in regular time.
