Description

technical field [0001] The invention belongs to the technical field of non-destructive detection of defects in pressure bearing rolling bearings, and in particular relates to a pressure bearing detection device based on oil spectrum analysis and magnetic flux leakage detection. Background technique [0002] Rolling bearings are an important part of contemporary pressure-bearing equipment. The main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. However, it will inevitably be worn or even broken during its use, seriously affecting property and safety. Therefore, it is very important to develop a rolling bearing defect detection device. [0003] In pressure-bearing equipment, in order to reduce friction energy consumption and wear material consumption, lubricating oil is usually added to rolling bearings, and these lubricating oils will carry wear particles and corrosion products of be...
