Technical characteristics and application field of bearing failure

The technical characteristics and application of high temperature bearings' faults in the process of using the device of high temperature bearing, often there are some problems is unavoidable. Importantly, if present know what problem in high temperature bearing type, the ability to take corresponding measures, to prevent actively repair, China's experience, the basis of high temperature bearing network, related to the high temperature bearing has six main technical problems, and analysis of six stop corresponding characteristics and application technology of the high temperature bearing problem. 1, the vibration diagnosis technology simply by high temperature bearing components is fatigue spalling, indentation, or part of the main corrosion, high temperature bearing in the process of enterprise operation will continue to present a periodic pulse control signal. This has a periodic signal can be device in high temperature sensors on the bearing ( Type speed or acceleration) To accept, through the analysis of vibration data to diagnose and high temperature bearing fault. General characteristics: vibration diagnosis technology; To on-line monitoring is complete; Rapid diagnosis, diagnosis theory has matured. Application research scope: special choose suitable for high temperature bearing fault monitoring of rotating machinery. 2, ferrographic diagnosis technology of high temperature bearing wear particles close contact with working conditions. With smooth oil of wear particles by magnetic field. Under the effect of magnetic field, the particle precipitation on the iron instrument according to certain rules. Iron spectrometer can undertake qualitative check on ferrographic microscope, also can be tested on the quantitative instruments. Judge working condition of high temperature bearing. Features: the machine does not need to collapse; Less investment, good effect; To find the early high temperature bearing fatigue failure; A study on the wear mechanism of can. Application range: applicable to smooth the high temperature of bearing fault diagnosis with smooth oil, high temperature bearing on grease for smooth more difficult. 3, the oil film diagnosis technology is smooth with good high temperature resistance influence bearing, due to the effect of different oil film, there is a lot of resistance between inner and outer ring data. So after continuous measurement of the resistance of the high temperature bearing inner and outer ring, can be recognized for high temperature bearing abnormal situation. Features: the environmental conditions can be used for the same working conditions of different social standards specification. Abnormal flake on appearance, indentation and crack of the diagnosis and treatment effect is poor. Application research scope: applicable to an axis of the leakage. 4 is a kind of monitoring and diagnosis technology, optical fiber monitoring surface to extract the signal directly from the high temperature bearing ring diagnostic technique. Made of fiber beam displacement sensor includes transmitting fiber beam and receiving optical fiber beam. By emitting light fiber beam surface and high temperature bearing clearance of the surface outside reflection, accepted by the receiving fiber beam, converted into electric signal by photoelectric component, and through the electrical signal analysis and processing. Bearing state of high temperature can be stopped. Features: high flexibility of fiber optic displacement sensor, signal extraction from the high temperature bearing surface directly, improve signal-to-noise ratio, high temperature can directly reflect the rolling bearing manufacturing quality, degree of wear and tear, load, smooth surface and clearance status. Usage: apply to install the sensor in high temperature bearing seat on the machine. 5, if high temperature bearing temperature diagnosis technology has some abnormal behavior, the temperature of the high temperature bearing will attack the time change. The previous: bearing fault handling and necessary maintenance measures, please collect the next: none
