一、油液含铁量检测技术现状 传统的油液含铁量检测采用光谱技术,现已比较成熟,能方便地检测出油液中各种金属元素的含量,而且有较高的测试精度,如国内引进的FAS-2C油液光谱仪。由于光谱仪只能测定油液中小于5微米的铁磨粒含量,因而对机器在异常工作期产生的大磨粒(一般大于10微米)缺乏检测能力。近十年来油液含铁量检测技术有了较大的发展,70年代美国研制的铁谱仪为分析油液中磨屑提供了一种新手段,但铁谱技术在完成油液含铁量的定量检测方面却不很理想,其定量误差一般在10％以上。为克服这些弱点,国外又发明了直读铁谱仪、旋转铁谱仪等,并将光强定量技术改进为磁矩测量技术,提高了测试精度,但仍不够理想。
First, the status quo of oil iron content detection technology Traditional oil content detection using spectroscopy, is now more mature, can easily detect the oil content of various metal elements, but also a higher test accuracy, Such as the introduction of FAS-2C oil spectrometer. Because spectrometers can only measure the content of iron particles less than 5 microns in the oil, they lack the ability to detect large abrasive particles (typically> 10 microns) that the machine generates during abnormal operating periods. In recent ten years, there has been a great development in the detection of iron content in oil. The iron spectrometer developed in the United States in the 1970s provided a new measure for the analysis of wear debris in oil. However, Quantitative detection is not very satisfactory, the quantitative error is generally above 10%. To overcome these weaknesses, foreign countries also invented the direct reading iron spectrometer, rotating iron spectrometer, etc., and light intensity quantitative technology to improve the magnetic moment measurement technology to improve the test accuracy, but still not ideal.
