INSTALLATION AND PROCESS OF FOLLOW-UP OF THE EVOLUTION OF THE QUALITY OF A LUBRICANT, METHOD OF FOLLOW-UP AND USE OF SUCH A METHOD FOR DETERMINING THE IRON CONTENT OF A LUBRICANT

摘要

An installation for following up the evolution of the quality of a lubricant circulating in equipment includes a conduit connected, upstream, to the piece of equipment and downstream to a recovery pan. A first controlled interruption valve circulates the lubricant in the conduit, a buffer reservoir accumulates lubricant, and a first bypass line is connected to the conduit, upstream from the first valve and to the buffer reservoir. A second controlled interruption valve circulates the lubricant in the first bypass line, a second discharge line discharges the lubricant, from the buffer reservoir to the recovery pan and a third controlled interruption valve circulates the lubricant in the second discharge line. A sensor determines content in a predetermined chemical element of a lubricant sample at the outlet of the buffer reservoir. This sensor includes an X-ray source and detector and a sample cell with a poly X-ray window.
