Title: Method for judging deterioration of lubricating oil
Inventor: ISE JUNICHI
IPC: G01N21/27
Filed: 1986-09-05
Abstract: PURPOSE:To prevent the seizure or operational inferiority of a bearing part or a slide part, by providing a photometric part to a lubricating oil recirculation passage and judging the deterioration of lubricating oil from the relation between the color difference of the lubricating oil measured by the photometric part and oxidation stability test data. CONSTITUTION:An oil monitoring window 4 is formed to a branch flow passage 3 and the photometric part 5 of a color-difference meter is provided to said oil monitoring window 4. In this photometric part 5, the color difference of lubricating oil is measured by a color-difference meter 6. When the measured value exceeds a control reference value, an alarm device 8 is operated. Said color difference is measured, for example, by using a xenon lamp in the CR-100 type hue color-difference meter manufactured by Minolta Co., for example, and oxidation stability is measured according to JISK2514. From such an aspect that definite correlation is present between the oxidation stability test data and color difference of the lubricating oil being deteriorated, the graph showing said correlation can be used in the judgement of the deterioration of the lubricating oil. In this case, since the judgement of oxidative deterioration due to the continuous measurement of the lubricating oil becomes easy, the seizure or operational inferiority of a bearing or slide part are prevented.
