METHOD AND DEVICE FOR THE ANALYSIS OF OILS AND TECHNICAL SERVICE FLUIDS AND FOR THE QUALIFIED EVALUATION OF THE OPERATING STATES OF UNITS

摘要

A method and device for analyzing oils, technical service fluids and for the evaluation of the operating states of units, wherein a drop of test fluid to be examined is applied to a test medium which is allowed to penetrate the medium, and is evaluated after a preselected time by optically comparing a resulting image with the data of a plurality of reference images with respect to a plurality of test criteria. The test fluids to be examined can give information about the state of the test fluids. Fast and reliable detection, evaluation, and assessment are possible and reduce the influence of subjective assessment influences. A computer-assisted comparison of the data of the images with the data of the reference images is performed. Data of the images from the front, back-light, and possibly the UV back-light recording are associated with images for a test criterion that has the greatest correspondence.

1. A method for the analysis of oils and technical service fluids and for the qualified evaluation of the operating states of units, wherein a drop of the test fluid to be examined is applied to a suitable test medium, is allowed to penetrate into the test medium and is assessed after a preselected time by a resulting test image being optically compared with the data of a plurality of reference images according to a plurality of test criteria, comprising the following method steps:
recording and storage of the data of a plurality of series of reference images for different test criteria and assignment of the reference images to specific properties of the fluids to be examined and operating states of units, recording and storage of the test image of the drop that forms on the test medium by means of an image recording apparatus at least in a front recording and a back light recording, computer-aided comparison of the data of the test images with the data of the reference images and assignment of the data of one or a plurality of images from the front and the back light recording to the reference images for a respective test criterion which has the greatest correspondence, and display and/or logging of the properties of the test fluid and/or of the operating state of the unit which correspond to the assigned data of the reference images.
