| 摘 要： | 通过对推力轴承多次解体检查和机组在变负荷时进行的调节阀开关试验,认为汽轮机轴向位移值异常是由润滑油流冲击轴向位移检测装置矢量板引起。对轴承油挡间隙和轴向位移检测装置防护罩进行了调整和改进,消除了缺陷,轴向位移值显示正常。

| Abstract: | 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. |
