【Abstract】 An on-line measuring installation using laser for measuring vertical bearing alignments in large turbine generators is presented, its measuring principle and characteristics are described in this paper. The instal lation has made on-the-spot tests several times in the 200MW turbogenerators, of course, have been acquiring important data of vertical bearing alignment changes. Ac cording to the measuring data to start-stop machines one can judge that the operation of installation is stable and the data is reliable.更多还原
