The vibration machinery and equipment used in the mining machinery industry must not lack one thing in production, that is, lubricants. Mining machinery and equipment have certain technical requirements for the selection of lubricants. It is not to say that any one can be used at will. Today, let's simply popularize the selection of lubricants in mining machinery and equipment, as follows:

1. The size of mining machinery and equipment is not exactly the same

But in general, it is relatively large, but the oil tank capacity of mining machinery and equipment is relatively small, so the amount of lubricating oil installed is relatively small, so when the mining machinery and equipment are working, Higher temperature will also appear, which requires that the lubricating oil has better thermal stability and oxidation resistance.

2. The use environment of mining machinery and equipment is relatively harsh

There are more dust impurities, so the lubricating oil is more susceptible to contamination, so it is required that the lubricating oil filled inside the mining machinery and equipment has relatively good rust and corrosion resistance and basic properties of anti-emulsification; and It is required that the basic properties of the lubricating oil cannot be changed greatly, and the sensitivity to pollution is also small.

3. When the mining machinery and equipment are used in the open air

The temperature change in summer and winter is very large, so the viscosity change of this lubrication is required to be relatively small. It cannot be said that at high temperatures, the viscosity is low, and a lubricant film cannot be formed. , The viscosity is too high, so that starting and running are more difficult.

4. Lubricants should have good flame resistance to avoid fire and explosion

If it is said that mining machinery and equipment are used in some places prone to fire and explosion accidents, then it is required to use a lubricant (flammable liquid) with good flame resistance, and cannot use flammable mineral oil.
