The following content refers to the thermal aspects of Gas Foil Bearing (GFB). GFBs are subgroup journal bearings, for which lubrication is provided by air, instead ‘traditional’ lubricants like oil, graces etc. Bearings offer specific features unachievable traditional bearings. GFB can operate with rotating speed up several dozens krpm in extreme temperature hundreds Celsius degrees. However d...

Abstract The bushing is one of the most important components power transformer, and it very to find internal defects bushings as soon possible, effectively accurately diagnose its insulation state information. In this paper, active loss 500kV transformer have been analyzed, evaluation method based on proposed. To verify feasibility method, abnormal was selected analyze state. result shows that ...

The state of melt viscosity in injection process is significantly influenced by the setting parameters due to that the shear rate of injection process is higher than other processes. How to determine plastic melt viscosity during injection process is important to understand the influence of setting parameters on the melt viscosity. An apparatus named as pressure sensor bushing (PSB) module that...
