Paper Abstract
In this paper, on the basis of traditional rotor fault diagnosis and vibration measurement technology, and combined with rotor dynamics, a virtual instrument and digital signal processing technology, an online monitoring system for the rotor of a roots blower is set up. The system is made up by a sensor, a signal conditioning circuits, a data acquisition cards and a computer. By the graphical design software LabVIEW, the signals of the rotor system such as speed, amplitude, frequency and axes orbit can be monitored in the real time-domain. Regarding the rotor vibration characteristics in the time- and frequency-domain as the major fault symptoms and using spectrum analysis or time-domain analysis to deal with all data, it provides the characteristics and mapping to inform about the operating state of the rotor system. Finally, by means of the model test, the dynamic characteristics of a rub-impact rotor are analyzed, and the reliability of the system is verified.
