Vibration source of water ring vacuum pump unit
There are many kinds of vibration sources in the working process of water ring vacuum pump units. They are not only the vibration source of the pump itself rotating movement, but also the vibration excitation of the prime mover (such as motor, diesel engine, etc.). When the chemical pump fails, there is also an impact effect inside its components, and at the same time, the water flow will also have a certain impact effect. Here is a brief introduction.
So many vibration sources mixed together will inevitably affect each other, and the fault signal is often submerged in the background noise and interference, which brings great difficulty to the pump fault diagnosis. The existing signal analysis methods have not made a breakthrough in the separation of vibration signals from multiple excitation sources and the feature extraction of vibration signals with low signal-to-noise ratio, but still need to do more Step by step.
At present, people mainly use data-based machine learning method for pump fault classification. The characteristic of this method is that a large number of sample data is needed, but when the sample data is difficult to obtain, this method shows its limitations. Therefore, it is necessary to study a small sample fault pattern classification method with higher generalization ability, so that it can use limited data samples to get better diagnosis results.
