At present, domestic neural networks and expert systems both use frequency-based signal characteristics. The different frequencies are shifted and stretched, and the frequency band information can be selected selectively, effectively reducing noise interference, and avoiding the amount of information that is redundant and unfocused.
For example, wavelet analysis is to decompose signals through a series of basis functions of different scales. Further development of fault diagnosis technology The operation and cost saving of large plum coupling units are of great significance to my country’s power production and technological development. Current status of vibration signal processing methods and prospects of new methods In recent years, the processing and analysis technology of vibration signal data in our country has gradually matured.
With the development of science and technology and the application of computer technology in the analysis of the cause of vibration failure, the stability of the vibration failure signal of steam turbine generator sets has also led to the development of vibration signal processing methods. Repeat the above method to fill the remaining bearings with grease to complete the grease filling maintenance of the cross-pack bearings in all directions.
The cardan shaft needs to be maintained at a fixed period CV Joint part Suppliers during the use process, so how to perform the maintenance work of the cardan shaft? What should be paid attention to in the maintenance of cardan shaft? Today we make an analysis from the structure of the cross shaft assembly: The bearing shell and the cross shaft are sealed with double-sided frame oil seals.
