XIE Cheng, ZHOU Yi-zheGuodian Beilun Power Generation Co Ltd no.1. ANALYSIS OF ABNORMAL AXIAL DISPLACEMENT IN STEAM TURBINE OF 600 MW UNIT MADE BY ALSTOM CORPORATION AND HANDLING THEREOF[J]. Thermal power generation, 2007, (12): 59-61. DOI: 10.19666/j.rlfd.2007.12.016.
Through repeatedly disassembling inspection as well as test under condition of varying load and on-off test of the governing value
it is believed from analysis that the abnormal axial displacement of the steam turbine is resulting from impulsion of the lubricating oil onto the vector plate of axial displacement detecting device. The clearance of oil damper in the bearing and the protective shelter of axial displacement detecting device have adjusted and retrofitted
the said defects being eliminated
the display value of axial displacement to be normal.
