The principle of the peak detector technology NSK Bearings Fault impact cycle is short (milliseconds), the energy distribution of the wide range of frequencies, the impact of a longer interval, and thus falls to the bearing component within the normal range of vibration frequency is very small. The conventional vibration signal acquisition and spectrum analysis and diagnosis of bearing failure, especially in the early NSK bearing failure is difficult to achieve.
The peak detecting techniques focus on the NSK bearing impact signal in which the impulse signal and the vibration signal frequency, and thus the effective separation.
Signal required for analysis is collected by the acceleration sensor, and the peak is taken from the selected time interval. Consistent with the band width of the selection of the time interval must do the sampling data for the analysis of a lot of vibration and the fast Fourier transform (F stare). , Then the sampling frequency is 2.56 times. , The peak time interval which must be greater than or equal to the reciprocal of the sampling frequency. So that the peak will be obtained in successive time intervals, until the is obtained next step for data necessary for processing. In order to monitor the impact, the signal collected by the acceleration sensor through a high-pass filtering (greater than 1 kHz), so that the signal is focused on the impact of the frequency band of the signal present at the same time separating the impact signal and the vibration signal.
Software RBMware RBMware online analysis software user interface is divided into two kinds of configuration interface and operation of the interface. Configuration interface using the virtual instrument technology, database set up, hardware setup, and debugging. Visually display the 4500 channel screen, click on the corresponding channel, you can easily set the channel parameters (type, range, unit, etc.). The running interface displays real-time status information, data collection needed to generate trend and frequency spectrum. Any authorized user in the LAN through the interface data browse and hardware configuration. RBMware online system analysis software can display different channel time domain, frequency domain waveforms as well as historical trend curve; dual-channel configuration, but also the Orbit, coherence, transfer function. And further analysis and diagnosis of the icon data and generate reports.
