| Abstract: | Based on the software of LabVIEW, a set of guide type of vibration signal acquisition and signal processing system is developed, in view of the vibration of roots vacuum pump signal mechanism and features, combined with the fault diagnosis technology. Using the USB 4431 data acquisition card producted by NI, the vibration signals of the pump body and gear box of roots vacuum pump are acquired，and the fault analyses of them are also carried out. The results show that various functions of the software can satisfy the requirements of condition monitoring and fault diagnosis, and verify that the software system is reliable and useful. |
