Fault diagnosis technology of rolling bearing vibration diagnostic technique, iron spectrum of diagnostic techniques, temperature diagnostic techniques, acoustic diagnostic techniques, the film resistance of diagnostic techniques and fiber-optic monitoring, diagnostic techniques, vibration, Tiepu temperature diagnostic technology, the most common.
A vibration diagnostic techniques
Bearing components of the work surface fatigue spalling, indentation or localized corrosion, the bearings run periodic pulse signal. Periodic signal can be installed in the bearing housing of the sensor (speed or acceleration-type) to receive, bearing fault diagnosis through the analysis of vibration signals.
Features: wide range of vibration diagnosis technology; online monitoring and fast; diagnosis, diagnostic theory has matured.
Applications: especially suitable for bearing fault monitoring of rotating machinery.
Iron spectrum diagnostic techniques
Bearing wear particles and their working conditions are closely linked. With the wear particles from lubricating oil through a strong magnetic field, the effect of a strong magnetic field, abrasive precipitated according to the laws of the chip in the iron spectrum, the iron spectrum piece in the iron spectrum microscope for qualitative observation or quantitative instruments to test , judge of the working conditions of the bearing.
Characteristics: the machine without disintegration; low investment, the effect is good; can be found early fatigue failure of bearings; do wear mechanism.
Applications: Suitable for lubricating the bearing fault diagnosis, the more difficult for the bearings with grease lubrication.
Film resistors diagnostic techniques
The well-oiled bearings, due to the role of the film, between the outer ring has a great resistance. Therefore, by measuring the bearing resistance of the outer ring of the bearing abnormal judgment.
Features: different working conditions using the same criteria. Surface spalling, indentation, cracks and other abnormalities in the diagnosis.
Application: Suitable for the occasion was exposed in the axis of rotation.
