Lithium based grease, due to its unique chemical and physical properties, exhibits many advantages in lubricating slurry pump bearings, making it an ideal choice. The following are some of the main advantages of lithium based grease in lubricating slurry pump bearings:
1. Good high-temperature stability
Lithium based grease, especially extreme pressure lithium based grease, has excellent high-temperature stability. In high-temperature environments, other types of lubricating grease may undergo dehydration and oxidation, leading to a decrease in lubrication performance or even failure. However, lithium based grease can effectively resist adverse factors in high-temperature environments and maintain excellent lubrication performance by adding special antioxidants and anti dehydration agents.
2. Excellent load-bearing capacity
In high temperature environments, the heat generated by friction is more likely to cause the dilution and detachment of lubricating grease, resulting in insufficient lubrication to reduce friction and wear. Lithium based grease has been specially treated to have a higher viscosity index and better shear resistance, providing more stable and long-lasting lubrication at high temperatures.
3. Excellent rust prevention performance
In high temperature environments, metal surfaces are more prone to rusting due to oxidation, thereby reducing the lifespan and performance of equipment. The rust inhibitor added to lithium based grease can effectively protect metal surfaces from corrosion and oxidation, thereby extending the service life of equipment and improving operational efficiency.
4. Good adhesion
In high-temperature environments, lubricating grease is prone to overflow or loss from lubrication points, making it impossible to provide sustained and effective lubrication. Lithium based grease can better adhere to metal surfaces by adding special adhesives and maintain stability under high temperature conditions, ensuring that the grease always covers the lubrication points and provides long-lasting lubrication effect.
5. Strong water resistance
Lithium based grease has good water resistance and can be used in damp and water contact mechanical parts. This is particularly important for equipment such as slurry pumps that are often exposed to humid environments, as the presence of moisture may cause emulsification and failure of other types of lubricants.
6. Good mechanical stability
Lithium based lubricants, especially those thickened with lithium 12 hydroxystearate, can be seen under electron microscopy to have soap fibers forming twisted bands with double strands and tangled together, thus exhibiting good mechanical stability. This means that lithium based grease is less prone to structural damage during use, ensuring its long-term lubrication effect.
7. Excellent colloidal stability
Lithium 12 hydroxystearate and lithium stearate have high bonding strength to the liquid phase on the surface of soap fibers and to the liquid phase inside the crystal lattice. Therefore, lithium based lubricants have good colloidal stability. This helps prevent oil separation in the grease, maintaining the uniformity and stability of the grease.
In summary, lithium based grease is an ideal choice for lubricating slurry pump bearings due to its high temperature stability, load-bearing capacity, rust prevention performance, adhesion, water resistance, mechanical stability, and colloidal stability. When selecting lubricating grease, the most suitable lithium based grease type should be chosen according to the specific working conditions and environmental requirements of the slurry pump to ensure efficient operation and long service life of the equipment.
