Lubrication method of slurry pump bearings

The lubrication methods for slurry pump bearings mainly include grease lubrication and oil lubrication. Lubricating grease is used for grease lubrication, while lubricating oil is used for oil lubrication. Choosing the appropriate lubrication method is crucial for the performance and lifespan of bearings.

Key facts and trends

Lubricating grease: Suitable for low-speed and light load applications, commonly used lubricating greases include calcium based, sodium based, lithium based, etc.

Oil lubrication: Suitable for high-speed and high-temperature applications, the viscosity of the lubricating oil is a key factor, usually between 12-15 centixtles.

Controversy and Different Perspectives

Some experts believe that grease lubrication is simpler and more cost-effective, suitable for most slurry pump applications.

Other experts advocate that oil lubrication is more effective in dissipating heat and protecting bearings under specific conditions, such as high temperature and high speed.

Maintenance cycle of slurry pump bearings

The maintenance cycle of slurry pump bearings refers to the interval between regular inspections, lubrication, and replacement. A reasonable maintenance cycle can help extend the life of bearings and improve the operating efficiency of pumps.

Key facts and trends

Regular inspection: It is recommended to replace the lubricating oil every 600-800 hours of operation.

Daily monitoring: Regular checks should be conducted on bearing temperature, vibration, and leakage during operation.

Controversy and Different Perspectives

Some studies suggest that dynamic maintenance cycles based on real-time monitoring data such as temperature and vibration may be more effective than fixed cycles.

Some people also believe that fixed cycle maintenance is simpler and more feasible, suitable for most industrial applications.

Selection of lubricating grease for slurry pump bearings

Definition and Explanation: Choosing the appropriate lubricant is crucial for the performance of slurry pump bearings. Different lubricating greases have different physical and chemical properties and are suitable for different working conditions.
