In actual condition monitoring, we often only need to judge the quality of rolling bearings and how long they can be used. If the power spectrum is not large, observe various frequency components in the spectrum. In order to get an accurate conclusion. When the vibration exceeded the vibration standard (such as the ISO2372 standard), the bearing kurtosis value also began Rapid increase. The larger the equipment capacity, the faster the speed.
In a large number of such accidents, we have also accumulated some practical skills, which is to monitor the vibration state of this type of bearing in the early stage of operation after installation, and perform spectrum analysis. If there is, Wholesale clutch bearings the bearing should be If there is no fault, please be vigilant and strengthen monitoring after troubleshooting other components. According to statistics, in rotating machinery using rolling bearings, about 30% of mechanical failures are caused by bearings.
After long-term practice and exploration, we have accumulated some practical skills in the actual fault diagnosis of rolling bearings. When diagnosing these counterfeit and inferior bearing faults, pay attention to accumulate the frequency spectrum and vibration time domain conditions of normal high-quality bearings on the equipment, so that bearing faults can be judged in time when such abnormal frequency spectrums occur, and equipment accidents can be avoided.
Later, various vibration measuring instruments and meters were gradually used and the root-mean-square value or peak-to-peak value of displacement, velocity or acceleration was used to determine whether the bearing was faulty. Many failures of rotating machinery are related to the state of rolling bearings. For example, the bearing cage suddenly breaks, the inner and outer rings of the bearing suddenly burn and break, etc. Good monitoring effect. In recent years, we have often encountered such situations in practice.
