Application and Optimization of On-Line Monitoring Technology of Final Polymerization Reducer
In the polyester plant,the rotating speed of the output shaft of the final polymerization reducer gearbox is less than 3 r/min,using vibration inspection method,it is difficult to detect the bearing fault sig-nal,and can not find the bearing fault of gearbox low-speed shaft through noise and temperature changes.Combined with a case of final polymerization reducer gearbox failure,by optimizing the state detection meth-od,the serious hidden dangers of the gear box are found in time,and the predictive maintenance of the equipment is realized.
