Generator Unit Vibration Swing System Design And Implementation Of Measurement And Failure Analysis

Along with modern technical of quick development, the single machine capacity of the water turbo-generator set is more and more big, the structure is also more complicated, and the machine set stability problem for following is also outstanding day by day.Along with the quick development of national economy, a large numbers of big, medium-sized even giant water electrical engineering set continuously devotion circulate, its stability is importance, if don't take into to control, will result in serious trouble.Therefore, to machine set the monitor for vibration status to carry on solid for circulating also develop vibration breakdown analysis to seem to be very important.This thesis made sure a water turbo-generator set the total design that the vibration puts a degree to measure system in studying the foundation of present condition analysis;Designed to used for the stalk signal that makes sure vibration directions takes place machine and used for the sample frequency occurrence machine that produces accurate sample frequency;Studied to spread a feeling machine the mark settle, sample frequency control, the signal number filter a wave, repeatedly the value calculation and rapid frequency chart analyzes of calculation method and software realization;The expert putting forward to analyze according to the rapid frequency chart diagnosis method.This system can be used for water power station to carry on a vibration to put the circuit examination of degree and broken down analysis, the application of this system can raise a machine set stability for circulating and prevent°from vibration putting to spend big but arouse of the breakdown shut down.
