1. Vibration diagnosis technology

    When the working surface of FAG imported bearing components has fatigue peeling, indentation or local corrosion, periodic pulse signals will appear during the operation of FAG imported bearing components. This periodic signal can be received by a sensor (velocity type or acceleration type) installed on the bearing seat, and the fault of FAG imported bearings can be diagnosed through the analysis of the vibration signal.

Features: Vibration diagnosis technology is widely used; online monitoring can be realized; diagnosis is fast, and the diagnosis theory is mature.

Application range: It is especially suitable for fault monitoring of FAG imported bearings in rotating machinery.

2. Ferrograph diagnostic technology

    FAG imported bearing wear particles are closely related to their working conditions. Pass the lubricating oil with abrasive particles through a strong magnetic field. Under the action of the strong magnetic field, the abrasive particles are deposited on the ferrograph according to a certain rule. The ferrograph can be qualitatively observed on a ferrograph microscope or tested on a quantitative instrument. According to this, judge the working condition of FAG imported bearings.

Features: The machine does not need to be disassembled; the investment is low and the effect is good; the early fatigue failure of FAG imported bearings can be found; the wear mechanism can be studied.

Application range: It is suitable for fault diagnosis of FAG imported bearings lubricated with lubricating oil, and it is difficult for FAG imported bearings lubricated with grease.
