How to choose the lubricating oil of pellet plant

What should be considered when choosing the lubricating oil of pellet plant? Since the lubricating oil used in different working conditions has big difference, the correct use of lubrication oil can prevent the failure of the pellet plant fundamentally.

When the friction pair is working at high temperature, lubricating oil with larger viscosity or grease with smaller penetration should be used to guarantee the normal work state of oil film thickness. On the other hand, lubricating oil of small kinematic viscosity oil or grease of large penetration should be used to ensure the fluidity of lubricating materials under low temperature.
 
When the working temperature of friction pair changes frequently, the selected oil or grease should have good viscosity-temperature properties, namely the consistency of the viscosity of oil or grease used has little change as the working temperature rising or falling. The oil film thickness value is required to be stable within a certain range to ensure the lubrication of kinematic pair.

When the working speed of pellet plant is higher, lubricating oil with small viscosity or grease with larger penetration should be used to ensure the liquidity and permeability of oil. Conversely, lubricating oil with large viscosity or grease with small penetration should be used in order to avoid the loss of grease. The viscosity and consistency of lubricating oil, of course, cannot be too large. Otherwise, it would increase the friction resistance and energy losses of pellet plant.
 
When the load of pellet plant is large, you should choose the lubricating oil with larger viscosity or grease with small penetration so as to guarantee the normal work condition of oil film thickness. Instead, lubricating oil of smaller viscosity or grease with large penetration should be used. When choosing the lubricating oil, pay attention to the physical and chemical performance of lubricating oil, such as the viscosity, corrosion resistance, anti-rust, flash point, water content, the impurity rate and acid value of lubricating oil, etc. Reduce the types and grade of lubricating oil as much as possible based on the actual performance, operation environment and the state of lubricating oil manufacturers on the premise of considering the comprehensive economic benefits, the lubrication requirements and the management in order to reduce the purchasing and storage cost of the lubricating oil of pellet plant.
 
The key parts of the imported equipment must be lubricated with imported lubricating oil in order to improve the lubrication performance and prolong the service life of pellet plant. Non-critical parts can be lubricated with domestic lubricating oil to reduce the costs.
