Zhefu Nuclear Power independently developed the lubrication property analysis program for gap throttling and capillary throttling hydrodynamic and hydrostatic journal bearings, and built a performance test bench for vertical slide bearings, which can test the capacity, stiffness, and damping factor of hydrodynamic and hydrostatic journal bearings. Based on the above, sodium-lubricated and lead-bismuth-lubricated hydrodynamic and hydrostatic journal bearings have been developed and put into practical use, and their performance has become industry-leading.
