To optimize the lubrication of a bearing, proper oil viscosity selection is essential.
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.
A shaft grounding ring and ceramic insulation can improve motor bearing life when VFDs are used.
Three design techniques can lower the operating temperature of hot running,
tilting-pad thrust bearings.
