Properly aligned bearings can be critical to the life and health of pumps.
Bearings
Bearings are small parts of pump systems that play a critical role. They bear the load of the pump, allowing rotation. They must be properly lubricated and temperatures monitored to prevent failure. These articles explain the causes of bearing failure and how to prevent them - thus protecting overall system life.
Appropriate bearing selection and best-practice maintenance procedures can make a difference in pump reliability, service life and production.
A Russian oil & gas company produces a compressor station to maximize pipeline capacity.
A northeast Germany refinery increased its MTBF by upgrading eight pumps.
This equipment eliminated a SAG copper mill gearbox’s maintenance issues resulting from contact lip seals that had a short and unreliable service life.
Use a mathematical model that estimates vibration at the top bearing of a motor used on a vertical, wet-pit, column type pump.
Mapping and testing ensure proper fit and function of replacement parts.
To optimize the lubrication of a bearing, proper oil viscosity selection is essential.
A shaft grounding ring and ceramic insulation can improve motor bearing life when VFDs are used.
