High power industrial machinery such as steam turbines and large pumps use journal bearings as rotor supports because this type of bearing is a high load carrying capacity. However, abnormal operating conditions in the journal bearings will degrade machine performance, shorten life time and increase the risk of operation. Bearing condition monitoring can detect faults at early stage and hence m...

The profile of sealing land is a sensitive factor affecting the thermo-hydrodynamic lubrication characteristics slipper pair. In this paper, non-uniform wear running surface under was presented and defined as boundary condition. Based on finite volume method successive over-relaxation iteration method, discrete numerical model coupled with temperature, pressure, thickness oil film constructed. ...
