Iron spectrum analysis: online monitoring technology of rolling bearings - bearing knowledge

Online monitoring technology of rolling bearings: iron spectrum analysis ( Bearing monitoring) : analysis type iron spectrometer, direct-reading spectrometer and on-line iron iron spectrometer. Iron spectrometer is usually divided into three broad categories. The use of high gradient magnetic field so that flow through the field sample contains solid foreign body, according to the size of the scale deposit on the glass, to observe the foreign particle shape, size, iron spectrum analysis technique is particularly suited to a method of identification and prediction rolling fatigue. Will be part of rolling bearing lubricating oil extraction as a sample. Colour and lustre and material, which can clearly determine the wear types, forecasting machine running status, found hidden danger in time. But for non-ferrous metals such as copper, sand, organic matter and seal clastic foreign body also has a fairly good identification ability. Iron spectrum technique in principle to identify the strong magnets, such as steel as the main target. Certainly bearing micro cracks started to appear fatigue. When the sample in length and thickness ratio of 10 1 fatigue spalling particles, when the sample in 1 5 microns diameter steel kind of spherical particles. And length is more than 10 microns, bearing the china-africa normal fatigue wear has started, when the length is more than 100 microns, bearing have failed. The length between 20 50 microns, the third fatigue clastic of length and thickness ratio of 30 1 fatigue flake. Wafer often with hollow. Fatigue began to appear, the chip can significantly increase the number of it as a sign of fatigue rendering with spherical particles.
