In a large chemical plant, the centrifugal pump is one of the key equipment, responsible for the transport of various chemicals. However, due to the influence of long-term operation and harsh environment, centrifugal pumps are prone to failure, resulting in production interruption and safety accidents. In order to solve this problem, the factory decided to use the pump group monitoring scheme provided by our company to monitor the running status of the centrifugal pump.

As can be seen from fig. 1 and fig. 2, there is obvious impact phenomenon on the waveform of the vibration envelope, with the peak-to-peak value as high as 50gE; And in the envelope spectrum, there is a frequency of 139Hz, with a high amplitude (7 m/s 2), accompanied by a multiple frequency doubling of 139Hz. After consulting the equipment information and confirming, it is the fault characteristic frequency of the outer ring of the bearing.
