There are some attentions about mining machinery lubrication you should know.
Small volume of mining equipment’s tank result in limited oil, meanwhile, the oil temperature is pretty high, so lubricating oil should take advantages of good thermal stability and antioxidant activity.
Because there is coal dust and rock dust around the mine, it is easy for lubricating oil to be polluted. So lubricating oil should be antirust and take advantages of corrosion resistance, emulsion resistance. When it is polluted, its performance can’t change much more.
There is big temperature difference between day and night in some places, so it will take an effect on the open-pit mine. The viscosity of lubricating oil can’t change over temperature. When the temperature is pretty high, viscosity will be reduced so that the lubricant film can’t be formed. And when the temperature is low, high viscosity will result in difficult operation.
In order to prevent the fire from destroying machines, lubricating oil should take advantages of flame resistance. Combustible mineral oil is forbidden.
Lubricant should be adaptive to seal components, in case they are damaged.
