THRUST BEARING MISALIGNMENT MONITOR |
摘要 |
17TU-2770 THRUST BEARING MISALIGNMENT MONITOR An apparatus for continuously monitoring the alignment condition of a thrust bearing based on a pair of temperature differences is adapted to utilize either analog or digital means. The monitor is particularly applicable for use in large turbines, particularly those coupled to generators for the production of electric power. Bearing misalignment and other variables are determined from temperature measurements of the oil feed temperature and from two temperature measurements made on diametrically opposite portions of the bearing surface. The apparatus of the present invention is made possible by observed predetermined relations between certain computed temperature differences which relate bearing thrust and misalignment moment and which also relate minimum oil film thickness and actual misalignment slope. |
