Embodiment Construction
[0048] By device M will Figure 1 to Figure 9 The device 2 shown in the figure is loaded into the figure 1 on the boat shown in the picture. In particular, the device M is an engine comprising a plurality of cylinders (for example, two to fourteen cylinders), preferably a two-stroke or four-stroke boat engine. A pipe 4 connects the device M to a pan 6 where the user recovers the lubricant. In practice, the engine oil flows in the conduit 4 with a pressure P4 comprised between 1.1 and 6 bar absolute. The oil flow rate in the pipe 4 can be low so that the oil trickles on the inner wall of the pipe.
[0049] The duct 4 runs vertically from the top of the device M to its bottom towards the disc 6 . In this embodiment, the oil flowing in the pipe 4 comes from at least one cylinder of the device M.
[0050] A tap connection 8 is provided on the pipe 4 and is equipped with a manually controlled valve 10 which offers the possibility of sampling a certain amount of oil leaving the...

Abstract
The device (2) for tracking changes in the quality of the lubricant circulating in the plant (M) comprises at least one conduit (4) and a sensor (50). The device also includes: a first controlled shutoff valve (20); a buffer reservoir (26); a first bypass line (28); a second controlled shutoff valve (32); a second drain line (42); A third controlled interrupt valve (44). The sensor (50) makes it possible to determine the bulk content of predetermined chemical elements of the lubricant sample at the outlet of the buffer reservoir using X-fluorescence techniques. The sensor comprises an X-ray source, an X-ray detector and a unit intended to contain a lubricant sample to be analyzed. The unit is equipped with a wall forming a window for the rays from the source to pass through or to go towards the detector, the wall being made of polyethylene terephthalate.
Description
【Technical field】 [0001] The present invention relates to a device for tracking changes in the mass of lubricant circulating in equipment, such as a ship engine. The invention also relates to a method for tracking changes in the content of a lubricant of a predetermined chemical element, in particular dissolved iron and / or particulate iron of the lubricant. Further, the invention relates to a method for tracking the operation of equipment on board a ship. [0002] The field of the invention is that of devices for analyzing lubricants, especially lubricants for engines, especially marine engines. 【Background technique】 [0003] In the field of internal combustion engines used on commercial ships it is known that the condition of the engine should be tracked by analyzing the lubricant circulating in the engine. This analysis makes it possible to detect wear and / or corrosion phenomena which are prone to occur in the engine. In the past, the operation of the engine was relati...
